Description

The so-called overhead line is a relative cable, which is a line that transmits electric energy by the tower to erect the conductor at a certain height. For the high-voltage transmission and distribution network overhead line insulation is generally air, the previous distribution line (10kV below 380V) generally also uses bare wire, but due to the complex urban distribution environment.

Standard

This product is produced according to the standard of GB/T12527-2008 "Overhead Insulated Cable with Rated Voltage of 1kV and Below".

Scope of application

It is applicable to overhead power lines with rated voltage of 10KV and below.

Features

• The rated voltage is 0.6/1KV, 10KV.

•  The cable laying temperature should not be lower than 0°C.

•  The maximum temperature of the cable in the event of a short circuit (the longest duration is not more than 5s): 160 °C for polyethylene insulation, 250 °C for cross-linked polyethylene insulation .

•  The long-term allowable working temperature of the cable conductor: polyvinyl chloride insulation should not exceed 70 °C, and cross-linked polyethylene insulation should not exceed 90 °C.

•  Allowable bending radius of the cable: The allowable bending radius of the cable should not be less than the diameter of the cylinder used in the cable bending test.
