I. From the Perspective of the Product Itself
(1) Specification Parameters
The specification parameters of the 35mm² green-yellow stranded copper
Ground Cable (PVC insulated, 600V) are important reflections of its performance and application range. Each parameter has undergone precise design and strict testing to ensure that the cable can play a stable and reliable role in the grounding circuits of various electrical systems.
In terms of conductor specifications, the conductor of the cable is a multi-strand copper
Stranded Wire with a cross-sectional area accurately controlled at 35mm². The
Copper Stranded wire is composed of multiple fine
Copper Wires with a diameter of about 0.2-0.3mm, and the number of strands is usually more than 100. This structural design not only enhances the
Flexibility of the conductor but also improves its overall mechanical strength. The DC resistance of the conductor at 20℃ is not more than 0.524Ω/km, and its excellent conductivity ensures that fault currents can be quickly and smoothly conducted into the ground.
The parameters of the insulation layer are also crucial. The insulation layer made of polyvinyl chloride (PVC) material has a uniform thickness of not less than 1.0mm. The dielectric strength of the insulation layer is not less than 18kV/mm, which can effectively block the current and prevent short circuits between the ground cable and other conductors. In addition, the volume resistivity of the insulation layer at 20℃ is not less than 1×10¹⁴Ω·cm, which further ensures the reliability of its insulation performance.
The rated voltage of the cable is 600V, which makes it suitable for the grounding circuits of low-voltage electrical systems and can meet the voltage requirements of grounding systems in most industrial, commercial and civil buildings. In the case of a short circuit, the cable can withstand a large short-time withstand current, and the specific value can reach a certain range according to relevant standard tests, ensuring that it will not be damaged due to overcurrent in case of a sudden short circuit.
The overall outer diameter of the cable is about 10-12mm, and the specific size will fluctuate slightly due to minor differences in production processes and insulation layer thickness. This outer diameter size makes the cable have good flexibility during laying and can adapt to different installation environments, such as pipe threading and underground burial.
In terms of temperature performance, the normal operating temperature range of the cable is -15℃ to 70℃, and within this temperature range, all performance indicators of the cable can remain stable. When the ambient temperature exceeds 70℃, its current-carrying capacity needs to be reduced; in low-temperature environments below -15℃, the flexibility of the cable will decrease slightly, but it can still meet the basic laying requirements.
In addition, the bending radius of the cable is also clearly specified. The static bending radius is not less than 4 times the outer diameter of the cable, and the dynamic bending radius is not less than 6 times the outer diameter of the cable. This parameter ensures that the cable will not be damaged due to excessive bending during installation and use.
(2) Characteristic Uses
The 35mm² green-yellow stranded copper ground cable (PVC insulated, 600V) has irreplaceable characteristic uses in many fields relying on its unique performance and design, providing an important guarantee for the safe operation of electrical systems.
In the field of industrial production, this cable is widely used. In the production workshops of large factories, the metal shells of various large mechanical equipment such as CNC machine tools, punch presses, injection molding machines, etc., must be reliably grounded to prevent electric shock accidents caused by equipment leakage. The cable can effectively connect the equipment shell with the grounding electrode. When the equipment leaks, the fault current can be quickly conducted into the ground through the cable, thus ensuring the life safety of operators. At the same time, in some dangerous places with flammable and explosive gases, such as the production workshops of chemical plants, the ground cable can effectively eliminate static electricity, prevent static sparks from causing explosions or fires, and provide a strong guarantee for safe production.
In commercial buildings, this cable also plays an important role. In crowded places such as large shopping malls and office buildings, there are many electrical equipment, such as central air conditioning systems, elevators, lighting equipment, etc., and the grounding of these equipment is crucial. The cable can connect the metal parts of these equipment with the grounding grid of the building to form a complete protective grounding system. Once the equipment leaks, it can quickly conduct the current into the ground, avoiding harm to personnel due to the charged equipment shell. In addition, in the lightning protection grounding system of commercial buildings, the cable can be used as a key line connecting lightning rods, lightning strips and grounding electrodes, safely conducting the strong current generated by lightning into the ground, and protecting the building and internal equipment from lightning damage.
The electrical safety of residential communities is also inseparable from this cable. In the power distribution system of residential buildings, the distribution boxes of each household and the metal shells of household appliances need to be connected to the grounding grid through ground cables. When household appliances leak, the ground cable can quickly conduct the current away, and cooperate with the residual current device to cut off the power in time to prevent residents from getting an electric shock. In the public facilities of the community, such as equipment in pump rooms and power distribution rooms, this cable also needs to be used for grounding to ensure the safe operation of public facilities.
The municipal engineering field is also an important application scenario for this cable. In the lighting system of urban roads, the metal lamp posts of street lamps need to be reliably grounded to prevent electric shock to pedestrians caused by street lamp leakage, and this cable can meet this demand. In urban rail transit systems such as subways and light rails, the grounding of rails and related electrical equipment is an important link to ensure driving safety, and this cable can be used for the grounding connection of these equipment to ensure the stable operation of the rail transit system. In addition, in urban municipal facilities such as sewage treatment plants and waterworks, the grounding of various electrical equipment also depends on this cable to ensure the normal operation of the facilities and the safety of operators.
In the agricultural field, with the development of modern agriculture, a large number of agricultural electrical equipment such as irrigation water pumps and temperature control equipment in greenhouses have been widely used, and the grounding of these equipment also requires this cable. It can connect the equipment with the grounding electrode to prevent personal injury and equipment damage caused by equipment leakage, ensuring the smooth progress of agricultural production.
(3) Material and Style
Material
The material selection of the 35mm² green-yellow stranded copper ground cable (PVC insulated, 600V) is the core guarantee of its performance. Each material is strictly screened to ensure the quality and reliability of the cable.
The conductor is made of high-purity electrolytic copper with a purity of more than 99.95%. High-purity copper has excellent conductivity and can conduct current quickly and efficiently, which is crucial for the ground cable, as it needs to quickly conduct fault current into the ground when equipment leaks or short circuits occur. At the same time, copper has good ductility and plasticity, which is easy to be processed into fine copper wires for stranding, and is not easy to break during stranding, ensuring the integrity and stability of the conductor. In addition, copper has good corrosion resistance and is not easy to be oxidized in normal environments, so it can maintain good conductivity for a long time.
The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which has excellent insulation performance and can effectively block current, preventing short circuits between the ground cable and other conductors. PVC material also has good mechanical properties, such as high tensile strength and elongation, which can withstand certain stretching and bending and is not easy to be damaged during cable laying and use. At the same time, it has good wear resistance and chemical corrosion resistance, which can resist the erosion of dust, moisture, acid, alkali and other substances in the external environment, protect the internal
Copper Conductor from damage, and prolong the service life of the cable. In addition, PVC material has good processing performance and is easy to be extruded, which can ensure the uniform thickness and smooth surface of the insulation layer.
The outer skin of the cable is green-yellow, and the pigment used has good light resistance and heat resistance, which is not easy to fade during long-term use, and can always maintain a striking color, ensuring that installers can quickly identify the grounding function of the cable and avoid misconnection.
Style
The cable is a single-
Core Cable style, that is, there is only one 35mm² copper
Stranded Conductor inside, wrapped with a layer of
PVC Insulation layer. This simple structure makes the cable have high flexibility during laying and can adapt to various complex installation environments.
The
Single-Core Cable is more convenient for pipe laying. Due to its compact structure, it can easily pass through narrow pipes, reducing the installation difficulty. At the same time, the single-core cable has good heat dissipation performance. The heat generated during current conduction can be quickly dissipated through the insulation layer, avoiding the impact on the cable performance due to heat accumulation.
The appearance of the cable is round with a smooth surface, and the green-yellow color is evenly distributed, which is bright. It not only has good recognition but also gives people a neat and standardized visual feeling. This style design conforms to international general cable standards, facilitating unified use and management in various electrical systems.
(4) Production Process
The production process of the 35mm² green-yellow stranded copper ground cable (PVC insulated, 600V) is complex and rigorous. From raw material processing to finished product inspection, each link has strict quality control to ensure that the performance of the cable meets relevant standards and requirements.
The production process of the conductor first involves the drawing of copper rods. The copper rod made of high-purity electrolytic copper is drawn for many times through a wire drawing machine to make fine copper wires with a diameter of about 0.2-0.3mm. During the drawing process, it is necessary to strictly control the drawing speed and tension to ensure the dimensional accuracy and surface quality of the copper wire. The drawn copper wire also needs to be annealed. The copper wire is heated to a certain temperature (usually 300-500℃) and kept for a period of time, then slowly cooled to eliminate the internal stress generated during the drawing process, improve the flexibility and ductility of the copper wire, and facilitate the subsequent stranding process.
Copper wire stranding is a key link in conductor production. A number of annealed fine copper wires are stranded through a stranding machine to form a 35mm² copper stranded wire. During the stranding process, it is necessary to control the stranding pitch according to the design requirements to ensure the roundness and mechanical strength of the conductor. Too small a stranding pitch will increase the hardness of the conductor and affect flexibility; too large a pitch will reduce the mechanical strength of the conductor, so precise control is required. At the same time, during the stranding process, the copper wires must be tightly combined to avoid looseness or gaps to ensure the conductivity of the conductor.
The extrusion molding process of the insulation layer is also important. PVC granular raw materials are added into the hopper of the extruder, heated and melted, and then evenly extruded and wrapped around the copper stranded wire through an extrusion die to form an insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, extrusion speed and die size. Excessively high extrusion temperature will cause the decomposition of PVC materials and affect the insulation performance; excessively low temperature will make the PVC materials insufficiently melted, leading to defects such as bubbles and cracks in the insulation layer. The extrusion speed needs to match the traction speed of the copper stranded wire to ensure the uniform thickness of the insulation layer. The selection of die size should be based on the specification requirements of the cable to ensure that the outer diameter of the insulation layer meets the design standards.
The extruded cable needs to be cooled, usually by water cooling. The cable passes through a cooling water tank to quickly cool and solidify the insulation layer. The 定型 insulation layer has good mechanical properties and insulation performance. During the cooling process, the water temperature and cooling time must be controlled to ensure that the insulation layer can be fully solidified.
The cooled cable needs to be printed and color-marked. The model, specification, rated voltage, manufacturer and other information are printed on the surface of the cable through a printing machine. At the same time, special extrusion equipment is used to extrude and wrap the green-yellow outer skin material on the outside of the insulation layer (or directly form green-yellow during the extrusion of the insulation layer) to ensure that the color is uniform and bright, meeting the requirements of relevant standards.
Finally, the finished cable is strictly inspected. The inspection items include the DC resistance of the conductor, the thickness of the insulation layer, dielectric strength, temperature resistance, appearance quality, etc. Only cables that meet the standard requirements in all indicators can leave the factory for sale. At the same time, sampling tests will be carried out on the cables, such as bending tests, wear resistance tests, chemical corrosion resistance tests, etc., to verify the performance stability of the cables in various environments.
II. From the Perspective of General Product Information
(1) Packaging
The packaging design of the 35mm² green-yellow stranded copper ground cable (PVC insulated, 600V) fully considers the needs of protecting the cable, facilitating transportation and storage, and adopts a scientific and reasonable packaging method to ensure that the cable is not damaged during the entire circulation process.
For long-length cables, cable reels are usually used for packaging. There are two types of cable reels: wooden and steel. Wooden cable reels have low cost and relatively light weight, suitable for short-distance transportation and small-batch delivery; steel cable reels have high strength, large load-bearing capacity and good impact resistance, suitable for long-distance transportation and large-batch delivery. The size of the cable reel is determined according to the length and weight of the cable, generally with a diameter between 800-1200mm and a width between 300-500mm. During packaging, the cable is neatly wound on the cable reel, and appropriate tension is maintained during winding to avoid loosening or twisting of the cable. To prevent the cable from sliding off the cable reel during transportation, baffles are installed on both sides of the cable reel, and the height of the baffles is not less than 1.5 times the diameter of the cable.
After the cable is wound, a layer of plastic film is wrapped around its outside. The plastic film has good moisture-proof and dust-proof performance, which can effectively prevent the cable from being polluted by moisture, dust and other impurities during storage and transportation, and protect the insulation layer of the cable from damage. For cables transported or stored in some special environments, a layer of linen or woven bag is wrapped outside the plastic film to further enhance the protection of the cable and prevent the cable from being collided and worn.
Clear labels are fixed on the cable reel, which detail the cable's model, specification, length, rated voltage, production date, production batch number, manufacturer, implementation standard and other information, facilitating customers to quickly identify and check during receipt and acceptance. At the same time, some warning information such as "Do not invert", "Handle with care", "Moisture-proof and sun-proof" is marked on the label to remind transportation and handling personnel to operate correctly.
For short-length cables, such as samples or retail short-section cables, they are usually packaged in coils. The cable is wound into a coil with a diameter of 300-500mm and fixed with plastic straps to prevent the coil from loosening. Then the coil is put into a plastic packaging bag, which is printed with the same product information as the cable reel label, convenient for customers to carry and use.
(2) Transportation
The transportation process of the 35mm² green-yellow stranded copper ground cable (PVC insulated, 600V) needs to strictly abide by relevant regulations and operating procedures to ensure the quality and safety of the cable.
Before transportation, a comprehensive inspection of the cable packaging is required to confirm whether the cable reel is firm, the cable is neatly wound, and the packaging is intact. For wooden cable reels, check whether there are damages, deformations, etc.; for steel cable reels, check whether the welding joints are firm and whether there is rust. At the same time, appropriate transport vehicles and transportation methods should be selected according to the specification, weight and transportation distance of the cable. Ordinary trucks can be used for short-distance transportation, and container trucks or special cable transport vehicles are more suitable for long-distance transportation to reduce bumpy and collisions during transportation.
When loading and unloading cables, special lifting equipment such as cranes and forklifts must be used. It is strictly forbidden to manually drag or roll the cable reel at will. When using a crane for loading and unloading, the sling should be firmly tied to the shaft holes on both sides of the cable reel to ensure balanced lifting and avoid tilting or falling of the cable reel. The lifting and lowering processes should be operated slowly to avoid damage to the cable reel and cable due to excessive impact. When loading and unloading with a forklift, the forks of the forklift should be inserted into the bottom of the cable reel to keep the cable reel stable, and single-fork lifting is strictly prohibited.
During transportation, the cable should avoid direct sunlight, rain and exposure. Direct sunlight and exposure will cause the temperature of the cable insulation layer to rise, accelerating the aging of the insulation layer; rain may cause the cable to get damp, affecting its insulation performance. Therefore, the transport vehicle should be covered with a tarpaulin to provide effective protection for the cable. At the same time, the cable should be kept away from heat sources and corrosive substances such as engine oil and acid-alkali solutions to prevent the cable from being damaged by high temperature and chemical corrosion.
The transport vehicle should drive smoothly during driving, avoiding sudden braking, sharp turns and violent bumps to prevent the cable from sliding and colliding in the vehicle. There should be a certain gap between the cable reels, which should be fixed with wooden wedges or other items to prevent the cable reels from colliding with each other. For long-distance transportation, the condition of the cable should be checked regularly. If packaging damage or cable abnormalities are found, the vehicle should be stopped for treatment in time.
After arriving at the destination, the cable should be unloaded to a flat, dry and ventilated site, away from fire
ult currents into the ground when equipment leaks or short circuits occur. At the same time, copper has good ductility and plasticity, which is easy to be processed into fine copper wires for stranding, and is not easy to break during the stranding process, ensuring the integrity and stability of the conductor. In addition, copper has good corrosion resistance and is not easy to be oxidized in normal environments, which can maintain good conductivity for a long time.
The insulation layer is made of high-quality polyvinyl chloride (PVC) material, which has excellent insulation performance and can effectively block the current to prevent short circuits between the ground cable and other conductors. PVC material also has good mechanical properties, such as high tensile strength and elongation, which can withstand certain stretching and bending, and is not easy to be damaged during the laying and use of the cable. At the same time, it has good wear resistance and chemical corrosion resistance, which can resist the erosion of dust, moisture, acid and alkali and other substances in the external environment, protect the internal copper conductor from damage, and extend the service life of the cable. In addition, PVC material has good processing performance and is easy to be extruded, which can ensure the uniform thickness and smooth surface of the insulation layer.
The outer sheath of the cable is green-yellow, and the pigment used has good light resistance and heat resistance. It is not easy to fade during long-term use, and can always maintain a striking color, ensuring that installers can quickly identify the grounding function of the cable and avoid misconnection.

The handling result will be fed back to the customer within 3-5 working days, ensuring that customers' reasonable demands are met.
In addition, the company will regularly conduct return visits to customers who have purchased the cable to understand the use of the cable and collect customers' opinions and suggestions on the product and service.
