Medium voltage abc cable
Applications
Aerial Bundled cable ABC cable is used for overhead power transmission and distribution lines with the voltage from 1KV-35KV.Also can be installed in the street with dense trees close to the building site of urban construction.
Construction
Copper or aluminum conductor
Inner shielding layer
Xlpe insulation
Outer shielding layer

Working conditions of aerial insulation power cable

1)Rated voltage:1kv 10kv 35KV
2)The tallest work temperatuie of the cable conductor
XLPE insulation cable temperature +90°C
HDPE insulation cable temperature +75
3)During having a short a short (lasting less than 5 seconds)
The maximum temperature
XLPE insullsted cables is temperature + 250
HdPE insulsted cables is temperature +150
4)During the cable lying the ambient temperature must be above temperature +20
5)Bending radius allowance of the cable
