APPLICATION:
Extra high voltage cable is used widely in power transmission utilities and many other industries involved in water, renewable energy, nuclear and thermal power stations, airports, railways, steel, and other manufacturing industries. Lead Alloy Sheath/Corrugated Aluminum Sheath/ Poly-Al tape are used for radial water barrier.
PROPERTIES:
- Highly sophisticated Dry Cure Dry Cool (DCDC) Triple Extrusion process
- Unique CCV Line equipped EHT system for perfect concentricity
- Computerized vulcanizing & cooling systems as well as extruder heating control system
- In – line metal detectors for Semicon & XLPE materials which ensure removal of ferrous & non – ferrous metallic Impurities from compound before extrusion
- In – line fine dust separator for XLPE insulation to have homogenous & extra clean insulation
- Capacity to manufacture cables upto 220KV.
- Moisture barriers as per the customer requirement Poly-AL/Lead/Aluminium Corrugation.
Standard:
- IS 7098(3)
- IEC 60840
- IEC 62067
CONSTRUCTION:
Conductor
Aluminum/Plain tinned Cooper. Conductor above 1000 sq.mm cross section shall be segmental (Milliken) conductors.
Conductor Screening
Conductor screening of an extruded semiconducting XLPE compound shall be applied over the conductor.
Insulation
The insulation shall be of dry – cured super clean XLPE compound
Insulation Screening
The insulation screening consist of a layer of extruded semiconducting compound.
Mettalic Screening
Copper wire screen over Insulation screening.
Radial Water Barrier.
Moisture barriers as per the customer requirement Poly-AL/Lead/Aluminium Corrugation.
Longitudinal Water Barriers
Water Swellable Tapes to prevent water penetration between the core and mettalic sheath.
Sheathing
PVC/PE Sheath
