APPLICATION

BURY CABLE supplies this lead sheathed, tape armoured XLPE cable for fixed medium voltage distribution in industrial plants, substations and infrastructure. It combines a lead cover with metallic tape armour for projects specifying layered protection along the cable route.

Standards

IEC 60228

IEC 60502-2

Construction

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 : XLPE

Insulation screen : This will be a layer of semi-conducting crosslinkable compound which will be applied by triple extrusion process over the insulation.

Core identification

1 Core : Natural

3 cores : Black, Green, Brown

Inner sheath : PVC

KEY FEATURES

• Class 2 stranded copper, XLPE insulation and triple-extruded semiconducting conductor and insulation screens.

• PVC inner sheath and lead cover, followed by galvanized steel tapes for three-core cable or aluminium tapes for single core cable.

• Red special PVC outer sheath with optional UV resistance; the stated construction includes hydrocarbon resistance.

SELECTION NOTES

• Specify system voltage U0/U(Um), core count, conductor size, route, load and fault duty. Coordinate the metallic layers, bonding and terminations with the electrical design.

• Choose glands and handling arrangements for the lead sheathed, tape armoured construction. Specify the chemical environment, moisture exposure and UV option for the intended route.

• The maximum conductor operating temperature is 90°C; the separately stated operating range is -20 to 60°C.

FAQ

How is this cable constructed?

Copper conductors with XLPE insulation and semiconducting screens are combined with PVC inner sheath, a lead cover, tape armour and a special PVC outer sheath.

Which tape armour is used?

Galvanized steel tapes for three-core construction and aluminium tapes for single core construction.

What distinguishes it from the wire armoured version?

This product uses metallic tapes. The related SWA/AWA lead sheathed cable uses wires, with its own dimensions and accessory requirements.

What outer sheath options are available?

The stated sheath is red special PVC, with UV resistance available on request.

What should a project enquiry include?

Rated voltage, core count, conductor size, installation environment, bonding requirements, cable lengths and delivery details.
