The power cable as one of our main products, the specification and applianceof the power cable are listing as follows:

1.The standards

The power cable is mainly comEngineering & Construction Machinery plying withIEC 60502 standard, also can be produced according to OEM requirements and other standards, such asBS,DIN,ASTM, VDE, NFC standards, and so on.

2.the construction of the power cable for different voltage grade

Laying conditions: for lyaing under ground with large different altitude, be able to bear external machanical force and moderate pulling force.

3. the power cable's characteristic:

3.1 long time operating temperature for cable conductor is 90 degrees.

3.2 the highest temperature of the conductor in short circuit (no longer than 5 seconds) in not more than 250 degrees,

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.

3.3 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.

3.4 being laid, the minimum temperature of the cable shall not be lower thEtching Machine an zero degree. In the case of lower temperature, heating measures shall be taken.

We can also supply the OEM and customized products according to your request
