XLPE insulated power cable
Product description:1 Implementation standards
GB/T12706.1-2008 rated voltage 1KV (Um=1.2KV) and 3KV (Um=3.6KV) cables
2 purposes
Power cables are less affected by climate and surrounding environment, have stable transmission performance and high reliability. Therefore, power cables are often used in urban underground power grids, lead lines of power stations, and internal power supply of enterprises.
3 Usage Features
3.1 The maximum rated temperature of the cable conductor is 90°C.
3.2 During a short circuit (the longest duration does not exceed 5S), the maximum temperature of the cable conductor shall not exceed 250°C, and the overload temperature shall not exceed 130°C.
3.3 The ambient temperature when laying cables should not be lower than 0℃, and the minimum bending radius should not be less than the following regulations:
Single-core cable 20D (mm), armored cable 15D
Multi-core cable 15D (mm), armored cable 12D
Where D——represents the actual outer diameter of the cable
