Steel core aluminum stranded overhead insulated cable with Rated voltage 1kV and below
Product performance
1, the long-term allowable cable conductor Operating temperature:
Weathering PVC insulation, polyethylene insulation should not exceed 70 ℃;
The cross-linked polyethylene insulation should not exceed 90 ° C.
2, short circuit (the longest duration of not more than 5s) cable conductor should not exceed the maximum temperature:
Weathering PVC insulated overhead cable: 160 ℃
Weatherproof polyethylene insulated overhead cable: 180 ° C
XLPE insulated overhead cable: 250 ° C
3, the cable laying ambient temperature should not be lower than -20 ℃.
4, the cable to allow bending radius: cable diameter (D) less than 25mm cable, bending radius of not less than 4D. Cable diameter (D) greater than or equal to 25mm cable, bending radius should not be less than 6D.
This product according to GB / T 12527-2008 rated voltage 1kV and below the overhead insulated cable,
Rated voltage 1kV steel core aluminum wire core overhead insulated cable standard production
Overhead fixed laying, lead line.
The product is pressed in the copper, aluminum conductor, aluminum alloy extruded weatherability cross-linked polyethylene,
Weatherability Polyethylene or weatherability PVC insulation, cable is excellent and reliable,
But also has excellent physical and mechanical properties and electrical properties, resistance to electric marks, resistant to surface discharge,
Resistant to the atmosphere and so on. Cable laying gap is small, saving line corridor to reduce the occurrence of power supply accidents,
To ensure personal safety. Applicable to mountainous areas, forest areas, mining areas, cities and other occasions, is all-weather cable products.
