>Not drop restriction on laying

>Stable & process performance

>Strong ability to adapt to the environment

>Short circuit (the longest duration of not more than 5s)

>The highest temperature of cable does not exceed 250 °C

>The maximum normal operating temperature of conductor 70°C

>Good flexibility, easy maintenance, installation, simple structure

>AC rated voltage 0.6/1kv,50 HZ for the fixed installation , transmission and distribution lines.

In cable laying, to ensure sufficient mechanical tension in the case of not drop restrictions, but the single core cable can’t be laid in the iron pipe, it’s also not permissible for using steel instrument around and fix the cable .During the cable laying ,its temperature is not less than zero,
