The specification parameters of the XV U1000 R2V 3-Phase 16mm² 5-Core 5g35 copper conductor insulated Electrical Power Cable are the specific quantitative embodiment of its performance. Each parameter is precisely designed to meet the stringent requirements of low-voltage three-phase power distribution systems.

The conductor uses high-purity electrolytic copper of 5g35 specification with a purity of ≥99.95%. This purity level can minimize resistance loss during current transmission. The single wire diameter of the 16mm² main core is 0.25mm, and multiple single wires are stranded together through a bunch stranding process. The stranding pitch is controlled within 15-20 times the diameter of the single wire, which not only ensures the Flexibility of the conductor but also avoids looseness caused by overly loose stranding. At 20°C, the DC resistance of the main core is ≤1.15Ω/km, and the DC resistance of the auxiliary core (taking 4mm² as an example) is ≤4.61Ω/km, both far lower than the limits specified in the GB/T 5023 standard, ensuring efficient power transmission. The elongation at break of the conductor is ≥30%, which can withstand the tensile force during laying without breaking easily.

The rated voltage of this cable is U1000V, that is, the phase voltage is 1000V and the line voltage is 1732V, suitable for low-voltage power distribution systems. The thickness of the insulation layer is 0.8mm, and it can withstand a voltage of 3000V without breakdown in a 1-minute power frequency withstand voltage test. The insulation resistance is ≥100MΩ·km at 20°C, and the volume resistivity is ≥1×10¹³Ω·cm. The excellent insulation performance effectively prevents leakage and short-circuit accidents. In addition, the partial discharge amount of the cable is ≤10pC under 1.73U0 voltage, further ensuring the stability of the insulation.

The overall structural dimensions of the cable are precisely calculated to balance performance and installation convenience. The conductor diameter of the 16mm² main core is 5.1mm, and with the 0.8mm insulation layer, the Single Core diameter reaches 6.7mm. The cabling diameter after stranding 5 Cores is approximately 18mm, and after wrapping with a 0.6mm thick sheath, the final outer diameter of the cable is 19.2mm. The minimum bending radius is 6 times the outer diameter of the cable, which is 115.2mm. This parameter enables the cable to be flexibly laid in narrow spaces such as inside distribution boxes and wall trunking.

The long-term allowable operating temperature of the cable is 70°C. In case of a short circuit (duration ≤5s), the maximum temperature can reach 160°C, which can withstand instantaneous high-temperature impact without damaging the insulation layer. Its minimum laying temperature is -15°C, and when laid at this temperature, the cable sheath has no cracking, meeting the installation requirements in cold regions. At the same time, the cable performance remains stable in the temperature cycle test from -30°C to 70°C, with no obvious aging or cracking of the insulation layer and sheath.

The sheath of the cable has good mechanical strength, with a tensile strength of ≥12MPa and an elongation at break of ≥150%, which can withstand mechanical collisions and friction during laying and use. In the impact test, a 1kg weight is dropped freely from a height of 1m to impact the cable, and after the impact, the insulation performance and conductivity of the cable have no obvious changes. In the flexing test, after 20,000 bending cycles, the cable has no open circuit or short circuit, and the insulation resistance remains within the qualified range.

The conductor uses high-purity electrolytic copper, which is refined by electrolysis to remove impurities and has excellent conductivity. Compared with ordinary Copper Conductors, high-purity electrolytic copper has higher conductivity, which can reduce energy loss during current transmission. At the same time, its good ductility allows the Copper Wire to be drawn into fine single wires, facilitating the bunch stranding process and improving the flexibility of the conductor.

The insulation layer is made of polyvinyl chloride (PVC) material, which has good dielectric properties, chemical corrosion resistance and processing performance. The PVC Insulation layer is designed with a special formula, with a temperature resistance level of 70°C, and can maintain stable insulation performance within a certain temperature range. Compared with other Insulation Materials such as rubber, the PVC insulation layer has higher mechanical strength, is not easy to be damaged, and has a relatively low cost.

The sheath is also made of PVC material, but its formula is different from that of the insulation layer. The PVC of the sheath is added with flame retardants, anti-ultraviolet additives, plasticizers, etc. The addition of flame retardants makes the sheath have good flame retardant performance, which can inhibit combustion in case of fire; anti-ultraviolet additives improve the weather resistance of the sheath, extending the service life of the cable when used outdoors; plasticizers make the sheath have certain flexibility, facilitating the bending and laying of the cable.

The cable adopts a circular stranded style, with 5 cores stranded together according to a certain stranding pitch, and the outer part is wrapped with a sheath to form a circular cable structure.

In addition, according to the special needs of customers, sheath styles of different colors such as black and gray can also be provided to adapt to different installation environments and identification needs. For example, in the renovation project of ancient buildings, cables with sheath colors that coordinate with the architectural style can be provided to reduce the impact on the appearance of the building.

The production process of the XV U1000 R2V 3-Phase 16mm² 5-Core 5g35 copper conductor insulated electrical power cable strictly follows national standards and industry norms, and adopts advanced production processes to ensure the stability of product quality.

First, the high-purity electrolytic copper rod is drawn into a single wire with a diameter of 0.25mm through a wire drawing machine. During the drawing process, a special lubricant is used to reduce wear on the surface of the copper wire. Then, multiple single wires are stranded through a bunch strander. During stranding, the number of single wires is determined according to the cross-sectional requirements of the main core and auxiliary core. During the stranding process, by precisely controlling the stranding speed and tension, it is ensured that the Stranded Conductor has a tight and round structure, avoiding defects such as looseness and broken wires. After stranding, the conductor is annealed by heating it to 300-400°C and then slowly cooling it to eliminate internal stress in the conductor and improve its flexibility and conductivity.

The insulation layer is formed by extrusion. The PVC Insulation Material is added to the hopper of the extruder, heated and melted, and then uniformly extruded and coated on the surface of the conductor through a mold. During the extrusion process, the extrusion temperature, speed and pressure are strictly controlled to ensure that the insulation layer has uniform thickness, smooth surface, and no defects such as bubbles and impurities. The thickness deviation of the insulation layer is controlled within ±0.1mm to ensure the stability of insulation performance. After extrusion, the Insulated Core is cooled to quickly solidify and shape the insulation layer.

3 main cores and 2 auxiliary cores are stranded into a cable through a cabling machine. During stranding, a untwisting device is used to avoid excessive twisting of the insulated core during stranding, which may cause damage. During the cabling process, non-hygroscopic filling materials are filled between the cores to make the cabled structure more round and stable, and also play a buffering and protective role. The filling material is polypropylene rope, which has good Chemical Resistance and mechanical strength.

After cabling, enter the sheath extrusion process. The PVC sheath material is added to the extruder, heated and melted, and then extruded and coated on the outside of the cabled core through a mold to form the sheath layer. The process parameter control of sheath extrusion is similar to that of insulation extrusion, ensuring that the sheath layer has uniform thickness, smooth surface, and is closely combined with the cable core. The thickness of the sheath layer is 0.6mm, and the deviation is controlled within ±0.1mm. After extrusion, the cable is cooled, pulled and taken up to form the finished cable.

The finished cable needs to undergo a series of strict inspections before leaving the factory. Inspection items include appearance inspection, dimension measurement, insulation resistance test, power frequency withstand voltage test, partial discharge test, mechanical performance test, etc. The appearance inspection mainly checks whether the sheath surface of the cable is smooth and free of damage; dimension measurement ensures that the outer diameter of the cable, the thickness of the insulation layer and the sheath meet the requirements; electrical performance test verifies the insulation performance and conductivity of the cable; mechanical performance test checks the tensile strength, elongation at break and other indicators of the cable. Only cables that pass all inspection items can be labeled with a certificate of conformity and leave the factory.

The packaging design of the XV U1000 R2V 3-Phase 16mm² 5-Core 5g35 copper conductor insulated electrical power cable aims to protect the product, facilitate transportation and storage, and at the same time focus on environmental protection and clear identification.

Cables are usually packaged in reels, which are divided into wooden reels and steel reels. For cables with lengths of 100 meters and 200 meters, wooden reels are generally used. The wooden reels are made of high-quality pine wood, which has certain strength and toughness and can bear the weight of the cable. The diameter of the reel is 600mm, the width is 200mm, the thickness of the side plate is 20mm, and the hub diameter is 200mm, ensuring that the reel is not easy to deform during transportation and storage. For long-length cables with lengths of 500 meters and 1000 meters, steel reels are used. The steel reels are welded from steel plates, and the surface is galvanized, which has good rust resistance and can be reused. The diameter of the steel reel is 800-1200mm, and the width is determined according to the length of the cable, which can meet the packaging needs of long-length cables.

Before packaging, the cable needs to be neatly wound on the reel. During the winding process, the tension is controlled to avoid loosening or excessive stretching of the cable. After winding, the outer layer of the cable is wrapped with a layer of plastic film to prevent the cable from being contaminated with dust and moisture during transportation. Then, the cable is fixed on the reel with steel strips. The tightening force of the steel strips is moderate, which should ensure that the cable does not loosen and not excessively squeeze the cable to cause deformation. Iron rings for easy handling are installed on both sides of the reel, and the strength of the iron rings can bear the total weight of the reel and the cable.

Clear marks are printed on the side plates of the reel, including product model, specification (3-phase 16mm² 5-core), length, rated voltage, production batch number, production date, implementation standard, manufacturer's name, address and contact information, etc. These marks are convenient for users to identify the basic information of the product and for the manufacturer to carry out quality traceability. At the same time, a product certificate is attached to the reel, which indicates the inspection results of the product and the inspector's number.

In response to environmental protection requirements, packaging materials are strive to use recyclable and biodegradable materials.

During transportation, the reels are placed horizontally in the compartment, and wooden blocks are placed between the reels to prevent mutual collision. For steel reels, steel wire ropes can be used to fix them on the compartment to ensure that the reels do not shake during transportation. Railway transportation is suitable for medium and long-distance transportation. The reels are placed on the flat car of the railway freight car, and the same fixing method is adopted to ensure transportation safety. Waterway transportation is suitable for long-distance and export transportation. The reels are loaded into containers. The containers should be kept dry and ventilated, and buffer materials are filled between the reels to prevent damage to the cable caused by bumps during transportation.

During transportation, the reel should be prevented from being inverted or tilted at an excessive angle (not exceeding 15°) to prevent the cable from slipping off the reel. When transporting in rainy days, the cable needs to be covered against rain, and the reel is wrapped tightly with waterproof canvas to prevent rainwater from entering the cable and affecting the insulation performance. The driving speed of the transport vehicle should be moderate, avoiding sudden braking and sharp turns to reduce the vibration and impact of the reel. When loading and unloading cable reels, special lifting equipment such as forklifts and cranes should be used. It is strictly forbidden to manually drag the reels to avoid damaging the reels and cables. When lifting, the lifting tool should be hung on the special lifting ring of the reel, and not on the cable to avoid

ctor.
