Product Specifications
--Product Description
1.executive standard
GB/T 12706.1-2020
2.use
The product is suitable for power supply, transmission and distribution lines with rated AC voltage U0/U 26/35kV and below.
3.character
A) during normal operation of cable, the maximum conductor temperature shall be 70℃ for PVC insulation and 90℃ for XLPE insulation.
B) Maximum temperature of conductor during short circuit (maximum duration not exceeding 5 seconds) :
PVC insulation -- 160℃ for conductor cross section ≤300mm2, 140℃ for conductor cross section > 300mm2; Crosslinked PVC insulation at 250℃.
C) When laying cables, the ambient temperature shall not be less than 0℃, and the minimum allowable bending radius is as follows:
Single core cable: unarmored 20D, armored 15D
Multi-core cable: 15D for unarmored, 12D for armored
Where: D- actual outer diameter of cable.
D) Cable breaking force:
Aluminum core cable: 40×S (N)
Copper core cable: 70×S (N)
Note: S is the total cross-sectional area of the conductor
