Fire resistant cable


Standard: GB12666.6
Applications: For fire rated power distribution systems with rated voltages of 0.6/1KV and below

Fire resistant cable

  • The long-term operating temperature of the cable conductor is 70 ° C, and the XLPE insulation is 90 ° C.
  • When short circuit (maximum duration does not exceed 5S), the maximum temperature of cable conductor does not exceed 160 °C; XLPE insulation does not exceed 250 °C
  • When the cable is laid, the ambient temperature is not lower than 0 °C, and the minimum bending radius is:
    Single core 20 (D + d) mm; multi-core 15 (D + d) mm
    *D—the actual outer diameter of the cable mm; d—the actual outer diameter of the conductor mm
  • In case of fire, the cable can still be energized in the flame within 1.5h.
