Application

These power cables are used for electricity supply in medium voltage installation system. They are well adapted to underground use in industrial application where chemical and mechanical protections are needed.  This group is complying with IEC , BS and DEWA specs.
 

Design

1. Conductor

Stranded bare copper class 2 acc. to IEC 60228 or equivalent

2. Insulation

Triple extruded Inner semi conductive layer  - Cross Linked Polyethylene 'XLPE' - Outer semi conductive layer

3. Metalic Screen

Copper wire screen + Swelling layer in between the screen layer + Aluminum polymer laminated tape

4. First Sheathing 

Extruded Polyethylene armound the core

5. Inner Sheath or Bedding

Extruded PVC

5. Armour

Galvanized Steel Wire Armour "SWA"

6. Outer Sheath

Extruded Polyethylene with outer semi conductive layer
