35 kv and below crosslinked polyethylene insulated power cable
this product is suitable for fixed laying in ac fifty hz, rated voltage up to and including 35 kv power transmission and distribution line on transport electricity. compared with pvc insulated power cable, cross-linking power cable products not only has excellent electrical properties, mechanical properties, heat aging resistance, resistance to environmental stress and resistance to chemical corrosion resistance ability, and simple structure, light weight, not affected by laying head limit, long-term high operating temperature (90 ℃), and other characteristics.
use characteristics
1, cable conductor allow long the highest working temperature of 90 ℃.
2, short circuit (the longest duration is no more than 5 seconds) cable conductor of the most high temperature
degree of no more than 250 ℃.
3, cable laying environment temperature shall not be lower than 0 ℃.
4, cable minimum bending radius: three core cable not less than 15 cable diameter
times; single core cable not less than twenty times of cable diameter.
5, cable rated power-frequency voltage u0 / u for 0.6/1 kv ~ 26/35 kv.
