Product Core Advantages
– Stretchable PVC characteristics: The PVC sheath is made with a special stretch formula, which is flexible and elastic. Combined with the multi-strand bare copper wire core twisted design, it can withstand slight stretching (the stretching amplitude should not exceed 5% of its own length). It is suitable for laying in corners and narrow spaces in engineering buildings, significantly improving the convenience of construction and preventing cable damage during laying.
Advantages of bare copper wire core: The national standard specifies a high purity of bare copper, which has high conductivity, low transmission loss, and is convenient for wiring and laying at the construction site, thereby improving construction efficiency. At the same time, it is resistant to oxidation and corrosion, has a long service life (up to 30 years under normal operation), and reduces maintenance costs in the long run.
High insulation guarantee: The thickness of the cross-linked polyethylene insulation layer meets the standard. It is resistant to aging, moisture, and ultraviolet rays, with excellent insulation performance. It can effectively protect against the erosion of complex environments such as outdoor construction sites and damp conditions, avoiding the risks of leakage and short circuits, and ensuring the safety of construction power supply.
Special for engineering construction: 4×10mm² specification, suitable for low-voltage power transmission and temporary power supply requirements in engineering construction. Three-phase four-wire design, with low voltage drop and sufficient safety margin. No additional adjustment is required. Suitable for various construction scenarios in buildings.
Durable protection: The stretchable PVC sheath not only has stretchability but also possesses the properties of being wear-resistant, waterproof, oil-resistant, and corrosion-resistant. It can effectively protect the inner bare copper wire core and insulation layer, and is suitable for complex construction environments on construction sites, thereby extending the service life of the cable.
Flexible wholesale, convenient operation: Minimum order quantity is 10 meters. The procurement threshold is low, suitable for replenishment and emergency procurement needs at different stages of power engineering construction. Regular specifications are directly dispatched in stock, and can be delivered within 72 hours, without delaying the construction progress. Bulk purchases can be negotiated.
