BURY CABLE supplies this overall screened, wire armoured XLPE cable for fixed medium voltage circuits in substations, industrial plants and utility projects. The layered sheath system and wire armour provide a construction for routes requiring both electrical screening and mechanical protection.
IEC 60228
IEC 60502-2
Conductor : Stranded bare copper (class 2)
Conductor screen : This will be an extruded layer of semi-conducting crosslinkable compound applied under simultaneous triple extrusion process over the conductor along with the insulation and the insulation screen.
Insulation : Cross-linked polyethylene (XLPE)
Insulation screen : This will be a layer of semi-conducting crosslinkable compound which will be applied by triple extrusion process over the insulation.

Class 2 stranded copper and XLPE insulation, with semiconducting conductor and insulation screens applied by triple extrusion.
Overall aluminium/polyethylene tape screen, PVC inner sheath, HDPE sheath and polyamide intermediate layer.
Galvanized steel wire armour for multicore cable and aluminium wire armour for single core cable; red special PVC outer sheath.
Specify the network voltage U0/U(Um), core count, conductor size, fault duty, load and route conditions. Coordinate screen and armour bonding with the installation design.
Select glands and terminations for the armour material and agreed cable dimensions. Include UV resistance, chemical exposure and drum-length requirements in the order.
The stated operating range is -20 to 60°C; the maximum conductor operating temperature is 90°C.
Galvanized steel wires are specified for multicore construction, with aluminium wires for single core cable.
Aluminium/polyethylene tape, incorporated with PVC, HDPE and polyamide sheath layers.
XLPE surrounds the copper conductor, between the semiconducting conductor and insulation screens.
Red special PVC. UV resistance can be included as a specified option.
Core count, rated voltage, conductor size, overall diameter, screen arrangement and armour material establish the basis for gland and termination selection.
