The performance parameters

4.1 the conductor

Composed of aluminium or copper conductors, 800 was using die press circle under the ground, in order to achieve good roundness, large compression coefficient, etc. 800 was a conductor using die press round ground or integral structure. More than 800 was cross section conductor adopts split structure to reduce the conductor skin effect. Improve the cable transmission capacity.

The press can be processed according to customer's requirements, but also a conductor (round).

4.2 inside and outside the shielding

Conductor and insulation shield the semiconductive materials adopt crosslinking, ultra smooth type and can be adapted to three layers co-extrusion materials. Stripping insulation shield.

4.3 insulation

Insulation material is made of super purification 110 kv level of crosslinking polyethylene material. The purification of the production process feed system for the level of 100.

4.4 the waterproof layer and buffer layer

Cable such as waterproof demand, could be selected according to the use of different metal sleeve plus buffer layer or composite waterproof layer and buffer layer of waterproof structure. With half a conductive elastic buffer layer material, and has water absorption expansion performance.
