I. Information Related to the Product Itself
(I) Specification Parameters
E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120, 4×150, 4×185, 4×240 Sm cables have clear and detailed settings in terms of specification parameters, providing a solid foundation for their stable application in low - voltage power distribution scenarios.
The rated voltage of this series of cables is 0.6/1kV, among which 0.6kV is the phase voltage and 1kV is the line voltage. It fully meets the standard requirements of low - voltage power distribution systems and can be well adapted to common low - voltage power distribution equipment, ensuring voltage stability during power transmission and avoiding faults caused by voltage mismatch.
In terms of conductor specifications, there are various specifications such as 4×120, 4×150, 4×185, and 4×240mm². The continuous current - carrying capacity of the 4×120mm² cable is about 200A under standard working conditions; the continuous current - carrying capacity of the 4×150mm² specification can reach about 230A; the 4×185mm² specification can carry a current of about 260A; the continuous current - carrying capacity of the 4×240mm² specification is around 300A. The difference in current - carrying capacity of different specifications enables them to accurately match the power demand of different powers.
In addition, the insulation thickness of this series of cables varies according to specifications. The insulation thickness of the 4×120mm² specification is about 1.2mm. As the specification increases, the insulation thickness also increases accordingly. The insulation thickness of the 4×240mm² specification is about 1.4mm to ensure good insulation performance. The sheath thickness is also adapted to the specifications, generally between 1.8 - 2.2mm, providing reliable mechanical protection for the cable. Its minimum bending radius is 10 times the outer diameter of the cable, which can meet the bending needs of most laying environments. The operating temperature range is between - 15℃ and 60℃, which can adapt to conventional climate and environmental conditions.
(II) Characteristic Uses
E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120 and other specification cables play an important role in various low - voltage power distribution scenarios relying on their own performance characteristics and have a wide range of applications.
In the field of industrial plant power distribution, cables of 4×150mm² and 4×185mm² specifications perform well. There are many medium - sized production equipment in the production workshop of the factory, such as injection molding machines and milling machines. These equipment need stable power supply, and the 4×150mm² cable can meet their power demand. For the main power distribution lines in the workshop, which connect the main distribution boxes in multiple equipment areas, the 4×185mm² cable is more suitable. Its large current - carrying capacity can ensure stable power transmission when multiple equipment are running at the same time. At the same time, the
PVC Sheath has certain wear - resistant and oil - resistant properties and can adapt to the workshop environment.
This series of cables can also be used in the power distribution system of commercial buildings. For the power supply lines of high - power equipment such as central air - conditioning systems and elevators in large shopping malls, cables of 4×240mm² specification can be selected, and their sufficient current - carrying capacity can ensure the normal operation of these equipment. For the floor branch power distribution lines of the shopping mall, the 4×120mm² cable is more suitable. It can connect the floor distribution box with the electrical facilities of each store to meet the power demand of lighting, air conditioning, cash register equipment, etc. in the store.
In terms of public facilities, the power distribution lines of gymnasiums, exhibition halls and other places can also use this series of cables. The 4×120mm² cable can provide stable support for the power supply of lighting systems and scoring equipment in gymnasiums; while the exhibition hall holds large - scale exhibitions, the 4×150mm² cable can meet the demand for the power supply lines of temporarily built high - power equipment.
In addition, in some outdoor low - voltage power distribution scenarios, such as outdoor power distribution trunk lines in residential quarters, 4×185mm² cables can be used to connect the community substation with the distribution boxes of each building. The weather resistance of the PVC sheath enables it to be used stably in outdoor environments, and the characteristics of
Aluminum Conductors can also adapt to outdoor installation conditions.
(III) Material and Style
The material selection and style design of E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120 and other specification cables are fully combined with their performance requirements and application scenarios, providing a guarantee for the safe operation and installation of the cables.
The conductor is made of aluminum, and high - purity aluminum is selected with a purity of more than 99.5%.
Aluminum Conductors have good conductivity. Although their conductivity is slightly lower than that of copper, they can meet the needs in low - voltage power distribution scenarios. Moreover, the density of aluminum is small, which makes the overall weight of the cable light, reducing the handling difficulty and installation cost during laying. The aluminum conductor is processed by multi - strand stranding technology, which enhances its
Flexibility, enabling it to better adapt to bending paths during laying and reducing the risk of fracture. At the same time, the surface of the aluminum conductor is treated with anti - corrosion to form a protective film, which delays oxidation and corrosion and prolongs the service life.
The insulation layer is made of PVC (polyvinyl chloride) material. The
PVC Insulation layer has good insulation performance, which can effectively isolate the current and prevent electric leakage. Its voltage resistance performance meets relevant standards and can stably play an insulating role at the voltage level of 0.6/1kV. In addition, the PVC insulation layer also has certain temperature resistance and will not soften, deform or other situations that affect the insulation effect within the normal working temperature range.
The sheath is also made of PVC material. The PVC sheath is tough and has good mechanical strength, which can resist external slight extrusion, collision and other mechanical forces and protect the internal insulation layer and conductor. At the same time, it has certain weather resistance and can adapt to different temperature and humidity environments. It can also resist certain ultraviolet erosion when used outdoors. Moreover, the surface of the PVC sheath is smooth, which is convenient for the laying and installation of the cable and has good compatibility with laying facilities such as pipes and cable trays.
In terms of style, this series of cables has a 4 - core structure and is round as a whole. The 4 - core structure meets the needs of the three - phase four - wire power distribution system and can transmit three - phase electricity and neutral wire at the same time. The round structure enables the cable to bear uniform force during laying, which is convenient for winding and storage, and can better fit with the laying pipe to save installation space. The outer surface of the cable is printed with clear marks, including model, specification, rated voltage, manufacturer and other information, which is convenient for identification and traceability.
(IV) Production Process
The production process of E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120 and other specification cables is rigorous and standardized. Each link from raw material processing to finished product inspection has strict quality control to ensure that the product quality meets the standards.
The preparation of aluminum conductors is the first step of production. High - purity aluminum ingots are smelted and cast into aluminum rods, and then the aluminum rods are drawn into
Aluminum Wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the
Aluminum Wire is uniform and the surface is smooth. Then, according to the requirements of different specifications, multiple aluminum wires are stranded. During stranding, stable tension and appropriate pitch are maintained to make the conductor structure compact and round and enhance flexibility. The
Stranded Aluminum Conductor needs to be surface treated, and a corrosion - resistant protective film is formed through anodizing and other processes.
The insulation extrusion link is crucial. First, the PVC insulation particles are dried to remove moisture from the particles to avoid bubbles in the insulation layer. The dried PVC particles are sent to the extruder, melted at a set temperature (usually 160 - 180℃), and evenly coated on the outside of the aluminum conductor through a special extrusion die to form an insulation layer. During the extrusion process, the temperature, pressure and extrusion speed are monitored in real - time to ensure that the insulation layer has a uniform thickness, high concentricity with the conductor and a smooth surface without defects.
The cabling process is to strand 4
Insulated Aluminum Conductors together according to a certain stranding pitch. Filling materials are placed during stranding to make the cabled cable round. The filling materials are non - hygroscopic to prevent water from entering the cable. At the same time, stable tension is maintained during the stranding process to avoid loose conductors and ensure a
Compact Cable structure.
Sheath extrusion is the last key process. The PVC sheath particles are dried and sent to the extruder. After melting, they are evenly coated on the outside of the cabled conductor through an extrusion die to form a sheath. The extrusion process parameters are controlled to ensure that the sheath has a uniform thickness, is closely combined with the internal structure and has a smooth surface. The sheath can not only protect the internal structure but also make the cable have a unified appearance.
In the finished product inspection link, a comprehensive test is carried out on the conductivity, insulation performance and sheath mechanical performance of the cable. The conductivity of the aluminum conductor is checked through a DC resistance test, the insulation effect of the insulation layer is verified through insulation resistance and voltage withstand tests, and the mechanical strength of the sheath is inspected through tensile tests and impact tests. Only cables with all indicators qualified can leave the factory.
II. General Product Information
(I) Packaging
The packaging design of E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120 and other specification cables focuses on protecting the integrity of the cables during storage, transportation and handling, and at the same time takes into account the practicality of packaging and the clarity of identification.
For coiled cables, wooden cable reels are used for packaging. The diameter of the cable reel varies according to the cable specification and length, generally between 1.2 - 2 meters. Cables with larger specifications such as 4×240mm², due to their larger weight per meter, use cable reels with larger diameters to ensure stable bearing. The cable is neatly wound on the cable reel, and appropriate tension is maintained during winding to avoid loose,
Twisted Cables or surface damage caused by mutual friction. Both sides of the cable reel are equipped with baffles, and the height of the baffles is higher than the winding height of the cable to prevent the cable from slipping during transportation and storage.
The outside of the cable reel is wrapped with a layer of plastic film to play a role in moisture - proof and dust - proof, preventing the cable from being contaminated with dust and damp during storage and transportation. For cables that need long - distance transportation or storage in a humid environment, a layer of waterproof canvas is covered outside the plastic film to further enhance moisture - proof and sun - proof capabilities and avoid the impact of direct sunlight and rain on the cable.
A detailed label is pasted on the baffle of the cable reel. The label is marked with product name, model, specification, length, production batch number, production date, rated voltage, implementation standard, manufacturer name and contact information, etc. The label is made of wear - resistant and waterproof material to ensure that the information is clearly identifiable during transportation and storage. At the same time, warning signs such as "Handle with Care", "Moisture - proof", "Sun - proof" and "Do Not Press Heavily" are also marked on the label to remind relevant personnel to operate in a standardized way.
For small batches or short sections of cable samples, solid cartons are used for packaging. Foam liners are placed inside the cartons to fix the cables in the foam liners to prevent damage caused by shaking and collision during transportation. The outside of the carton is also marked with product - related information and warning signs.
(II) Transportation
The transportation of E - Ayy, Eayy, Eayy - J, Nayy - J 0.6/1kV 4×120 and other specification cables must follow strict specifications to ensure that the cables are not damaged during transportation and their performance is stable.
The transportation method is selected according to the transportation distance and quantity. For long - distance transportation with a large quantity, railway transportation or road freight is preferred. Railway transportation has good stability and can reduce jolting during transportation. The cable reels are fixed in the freight carriage, and steel wire ropes or special fastening belts are used to firmly connect the cable reels to the carriage to prevent sliding. For road freight, trucks in good condition with sufficient carrying capacity are selected. The carriage must be flat, clean and free of sharp debris. An appropriate gap is left between the cable reels, and they are separated by buffer materials to avoid mutual collision.
Short - distance transportation can use small trucks or logistics vehicles. Special hoisting equipment is required when loading and unloading cables. The hoisting point is selected at the central axis of the cable reel. Hoisting from the side of the cable reel or the cable itself is strictly prohibited to prevent deformation of the cable reel or damage to the cable. Handle with care during loading and unloading to avoid violent collision.
During transportation, attention should be paid to: Cables should avoid open - air transportation. If it is unavoidable, they should be covered with waterproof canvas to prevent exposure to the sun and rain; keep away from fire sources, heat sources and corrosive substances. Transport vehicles are not allowed to approach open fire areas and are not mixed with corrosive goods such as acids and alkalis; drivers drive steadily during transportation, avoid violent operations such as sudden braking and sharp turns, and reduce the shaking of cable reels; regularly check the fixing of cable reels and reinforce them in time if they are loose.
After arriving at the destination, the receiver shall check the packaging and appearance of the cable together with the transporter, and sign for it only after confirming that there is no damage. If there is packaging damage, cable appearance damage and other situations, photos should be taken and recorded in time, and communicate with the shipper and transporter for handling.
