republic of liberia XLPE insulated overhead cable
Product Description
Product introduction: This product is composed of pressed copper, aluminum (aluminum alloy) conductor, inner shielding layer and weather-resistant insulating material. Its structure is simple, safe and reliable. It has both the excellent electrical conductivity of power cables and the strong physical properties of overhead cables. Mechanical behavior. Due to the use of weather-resistant insulating materials, the product has excellent weather resistance and aging resistance. Compared with bare wires, this product has the characteristics of small laying gap and high reliability, especially suitable for high-rise buildings, jungle areas and climates. Use in harsh areas.
Use features:
1. The rated voltage of the cable is divided into three types: 1kV, 10kV
2. The long-term allowable working temperature of the cable: polyethylene insulation is 70 °C; polyethylene insulation is 70 °C; cross-linked polyethylene insulation is 90 °C
3. The maximum temperature of the cable during short circuit (the longest time is not more than 5 seconds): polyethylene insulation is 130 ℃; polyvinyl chloride insulation is 160 ℃; cross-linked polyethylene insulation is 250 ℃
4. The ambient temperature of cable laying is not lower than -20℃
5. The ambient temperature used by the cable is -40℃~40℃; the relative humidity is not more than 90% in the rainy season
6. The allowable bending radius of the cable: the cable with the rated voltage below 1kV: the outer diameter of the cable D≤25mm, the bending radius is not less than 4D; the outer diameter of the cable D>25mm The bending radius is not less than 6D.
Rated voltage 10kV cable:
Single-core cable: 20×(D+d)±5%; multi-core cable 15×(D+d)±5% In the formula: D- actual outer diameter of cable mm, d- actual outer diameter of cable conductor mm
