Product introduction

The product consists of compacted copper, aluminum conductor, inner shield layer and weather resistant insulating material and outer shield layer. The structure is simple, safe and reliable. It has excellent electrical conductivity of power cable and strong physical and mechanical properties of overhead cable. Due to the weather-resistant insulation material, the product has excellent weathering resistance. Compared with bare wires, this product has the characteristics of small laying clearance and high reliability, especially suitable for high-rise buildings, from jungle areas and bad weather. Regional use.

The use of features

1. Cable rated voltage is divided into two types: 1kV, 10kV

2. The cable has a long-term allowable working temperature; polyethylene insulation is 70 ° C; PVC insulation is 70 ° C; XLPE insulation is 90 ° C

3. When short circuit (maximum time is less than 5 seconds), the maximum temperature of the cable; polyethylene insulation is 130 ° C; PVC edge is 160 ° C; cross-linked polyethylene insulation is 250 ° C

4. The ambient temperature of cable laying is not lower than -20 °C

5. The ambient temperature of the cable is -40 ° C ~ 40 ° C; the relative temperature is not more than 90% in the rainy season

6. Allowable bending radius of cable; rated voltage below 1KV cable: cable outer diameter D≤25mm, bending radius not less than 4D; cable outer
diameter D>25mm, bending radius not less than 6D. Rated voltage 10KV: single core cable: 20 × (D + d) ± 5%; multi-core cable: 15 × (D + d) ± 5%
where: D- cable actual outer diameter mm, d- cable conductor Actual outer diameter mm
