Classification:

  • Product Description
  • 1. product use

    This product is suitable for fixed installation of rated voltage 0.6/1kV in distribution networks or industrial installations.

    Executive standard of 2. products

    Fire-resistant power cables are manufactured according to enterprise standards, and the fire-resistant characteristics meet the requirements of GB/T19666-2019.

    3. product characteristics

    Long-term allowable working temperature of cable conductor: PVC insulation 70 ℃, XLPE insulation 90 ℃.

    The temperature of the cable during short circuit (duration not exceeding 5s) is 160 ℃ for PVC insulation (140 ℃ for cross-section greater than 300mm2) and 250 ℃ for cross-linked polyethylene insulation.

    When laying cables, the ambient temperature should not be lower than 0 ℃, and preheating should be carried out when the temperature is lower than 0 ℃.
