Product Description

AL/XLPE/CTS/PVC/STS/PVC, Power Cable, 12/20 (24) KV, 3/C (IEC 60502-2)
The cable design conforms to IEC 60502 part 2. However if requested, we can separately offer guaranteed technical particulars for cables as per different international specifications or specific customer needs.

CONSTRUCTIONAL FEATURES

Conductor
Aluminum Conductors upto 1000 sq mm will be circular compacted & stranded and shall comply with IEC-60228 Class 2.

Conductor screen
This will be an extruded layer of semiconducting XLPE applied under simultaneous triple extrusion process over the conductor along with the insulation and the insulation screen.

Insulation
This will be an extruded layer of insulating grade XLPE applied over conductor screen under triple extrusion process along with conductor screen and insulation screen.

Insulation screen
This will be a layer of semiconducting XLPE which will be applied by tripe extrusion process over the insulation.

Metallic screen
It will consist of a layer of copper wires applied helically with overlap over insulation screen. Other combinations of metallic screens as per customer’s requirement can also be provided on request.

Inner Sheath (Bedding)
Extruded layer of PVC or PE is applied over the laid-up cores. PVC is normally of grade ST2 or PE of grade ST7 as per IEC 60502 Part 2.

Armour

The armour is applied over inner sheath. For Single core cables this is of aluminium wires and for multicore cables the armour can be of one among the following options: –
A) Galvanized steel wire.
B) Galvanized steel tape.
C) Galvanised steel strip.
The armour is applied helically over the bedding.

Outer sheath
An extruded layer is applied over the armour in case of armoured cables and over the laid up cores in case of unarmoured cables. Outer sheath material can be either PVC of grade ST2 or PE of grade ST7 as per IEC-60502 Part 2.
