XLPE insulated power cable price high voltage power cable

 

 

 

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

 

 

 

1.The standards

 

The power cable is mainly complying with IEC 60502 standard, also can be produced according to OEM requirements and other standards, such as BS, DIN, ASTM, VDE, NFC standards, and so on.

 

 

 

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

 

2.1 low voltage cable power cable

 

Low voltage (0.6/1 kv)

 

single core or multi-core

 

copper or aluminium conductor

 

pvc inusulation

 

steel tape armored or galvanized steel wire armored or unarmored

 

pvc outer sheath

 

power cable.

 

2.2 medium voltage cabel power cable

 

Voltage grade is up to 35kv,

 

cross-section area can be up to 1000 sqmm (copper or aluminiun conductor).

 

Conductor long-time operating temperature is 90 degrees.

 

In short circuit, conductor highest temperature should be not more than 250 degrees.

 

1kv-35 kv

 

multi-cores

 

copper or aluminium conductor

 

xlpe insulation

2.3 high voltage cable power cable

 

High voltage (35kv~220kv)

 

copper or aluminium conductor

 

xlpe insulation

 

metal sheath (lead or corrugated aluminium)

 

hdpe or pvc outer sheath power cable.

 

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 than 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
