Low Voltage 3 Core Electric Underground Cable with Aluminium

                          Low voltage 3 core electric underground cable with aluminium 

1. Application:

The low voltage 3 core underground electric cable is usually used to be buried directly, because it could bear large mechanical stress.  Aluminium and copper conductor are both OK for us.
 

2. Performance Characteristics:

The long time-term permissible operation temperation of conductor shall not be higher than 70 degree;

Conductor maximum short circuit( not more than 5s) temperature shall not be higher than 160 degree;
 

3. Construction:

Conductor: the conductor is the style 1 or 2 of IEC 60228;

Insulation material:
(1) thermoplasticity material:PVC ( polyvinyl chloride)   max condutor temperature 70;
(2) thermoset material: XLPE ( crosslinked polyethylene)  max condutor temperature 90C

inner covering and filler: the extruding and wrapping can both be used for inner covering layer.

                                      if it’s multi-core cable, it need to be filled full before wrapping;

                                      The binder tape can be used before extruded inner covering layer.

Metallic layer: the metallic layer can be optional for the 0.6/1kv elctric power cable

Metallic armour: The round or steel/aluminium wire or tape can all be used for armouring layer according to different application.
