Power cable's characteristic:
1) long time operating temperature for cable conductor is 90 degrees.
2) the highest temperature of the conductor in short circuit (no longer than 5 seconds) in not more than 250 degree
if a joint is in the cable, the temperature of the tinning welding joint is not more than 120 degrees, compressing joint not more than 150 degrees and electro-welding joint not more than 250 degrees.
3) no drop in limited provided there is full mechanical tention when cable is laid. It si forbidden to lay cable in iron-pipe or to fix cable by circling around the cable with iron materials.
4) being laid, the minimum temperature of the cable shall not be lower than zero degree. In the caselowtemperature, heating measures shall be taken.
