XLPE insulated power cables
XLPE insulated cables using chemical or physical methods, the molecular structure of the cable insulation polyethylene material change by the linear three-dimensional network structure, thermoplastic polyethylene into a thermosetting polyethylene, thereby substantially higherits mechanical properties, heat aging resistance, environmental stress cracking resistance and excellent electrical properties.
XLPE insulated cable conductors rated operating temperature is 90 ℃, than the oil impregnated paper insulated cables high and simple structure, small diameter, light weight, easy installation laying, but also has features not drop restrictions.
Our company is equipped with the advanced level in the warm water of the silane cross-linking and three-squeezed method of chemical cross-linking production line, the formation of a strong cross-linked polyethylene insulated power cable production capacity.
A, Application:
This product is suitable for AC rated voltage (U / U) 0.6/1KV system transmission and distribution lines.
B, Operation standard:
International GB/T12706-2008
C, Characteristics :
1, Cable conductor, the maximum allowable working temperature is 90 ℃; emergency overload temperature of 130 ° C; short circuit (5s) conductor maximum temperature of 250 ℃.
2, Ambient temperature when the cable laying should not be less than 0 ° C; below 0 ℃, the laying of the cable should warm-up.
3, The bending radius of cable: single-core cable of not less than 16 times the cable diameter; multi-core cable of not less than 12 times the cable diameter.
4, Carrying capacity, laying not drop restrictions
