Lead Sheath HV Power Cable 132 kV 1 × 800 mm2 , High Voltage XLPE Power Cable

TANO CABLE 132 kV 1 × 800 mm2 lead sheath High Voltage XLPE Power Cable

Construction of XLPE Power Cable

Conductor:Copper/Aluminium wire, stranded to BS 6360 class 2.
Conductor Screen: The conductor screen consists of an extruded layer of non metallic, semi-conducting compound applied on top of a semi-conducting tape. The conductor screen is applied under triple extrusion process over the conductor along with the insulation and the insulation screen. The extruded semi-conducting compound is firmly bonded to the insulation to exclude all air voids and can be easily hand stripped on site.

Insulation: Extruded cross-linked polyethylene (XLPE-GP8) compound insulation
Insulation Screen: The insulation screen consists of an extruded layer of non metallic, semi-conducting compound extruded over the insulation of each core. The extruded semi-conducting layer shall consist of bonded or cold strippable semi-conducting compound capable of removal for jointing or terminating.

Semi-conductive Water Blocking Swellable Tape: A semi-conducting tape shall be applied over the core assembly as a bedding for the metallic layer. The minimum thickness is 0.3 mm and the maximum resistivity is 500 Ohm-m at 90°C. The screen is tightly fitted to the insulation to exclude all air voids and can be easily hand stripped on site. The screen may be covered by semi-conductive water blocking swellable tape to ensure longitudinal watertightness.

Metallic Layer: The metallic layer may be applied over the core assembly collectively. The metallic screen shall consist of either copper tapes or a concentric layer of copper wires or a combination of tapes and wires.

Swellable Tape:Swellable material
Separation Sheath:Aluminum Tape sheath
Outer Sheath:Thermoplastic HDPE-ST3 compound
