Product Description

40/69kV XLPE Insulated PE Sheathed High Voltage Power Cables

 

Application

These single core cables are designed for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations. If the cable gets water inside due to the mechanical demages, swellable tapes prevent the movement of the water inside the cable.

Standard

IEC 60840

Construction

 

onductor	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.
Insulaton 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
