Standards of products
They are manufactured according to GB/T14049, Aerial Cable with rated voltage 10KV and 35KV.
Features
1. The rated voltages are 10(12) kilovolts and 35(42) kilovolts. These cables can be used in the system where the single phase earthed fault normally less than 1 minute each time of the system of maximum duration less than 8 hours each time, but the total duration not more than 125 hours.
2. Ambient temperature should be not lower than
3. Maximum temperature is
4. Minimum bending radius is as follows when cables are installed:
for single: core cable-20(D+d),mm
for multi: cores cable-15(D+d),mm
Note:D denotes the overall diameter of cable, while d means the diameter of conductor, unit: millimeter.
