15KV POWER CABLE CONSTRUCTION
Conductor:
Plain annealed stranded circular compacted copper conductor or
aluminum (Class 2).
Conductor Screen:
Extruded layer of a cross-linkable semi-conducting compound as a
stress control layer.
Insulation:
Extruded layer of cross-linked polyethylene (XLPE).
Insulation Screen:
Extruded layer of a cross-linkable semi-conducting compound firmly
bonded to the insulation.
Metallic Screen:
Flat plain copper tape helically applied over the insulation screen
with suitable overlap.
Filler:
Non-hygroscopic polypropylene filler suitable for the cable’s
operating temperature.
Bedding:
Extruded layer of Polyvinyl chloride (PVC).
Armouring:
Double layer of galvanized steel tapes.
Outer Jacket:
Extruded layer of Polyvinyl chloride (PVC).
15KV POWER CABLE APPLICATION
15kv power cable is used for power distribution networks; also for
connection to generation units and plant and process connection.
The mv cable could be laid directly in ground, outdoors, indoors
and in cable ducts.
