19/33KV Medium Voltage Power Cables Monopolar Cable 1x95sqmm Unarmored BS 6622

19/33KV MV Power Cables Monopolar Aluminum Cable 1x95sqmm Unarmored BS 6622

Applications:

The single core cables are designed for distribution of electrical power with nominal voltage Uo/U ranging from 3.8/6.6KV to 19/33KV and frequency 50Hz. They are suitable 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.

Standard:

BS 6622

BS 7835 (LSZH Version)

Noted:Single Core Cables to BS 6622/BS 7835/IEC 60502/VDE 0276

Construction:

Conductors

Either aluminium or copper conductors are used. Conductors up to 630mm² will be circular, compacted & stranded and shall comply with IEC 60228 class 2. 630mm² conductor will be circular stranded type on which a layer of semi-conducting tape will be applied.

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. The triple extrusion is a single high precision operation that eliminates the possibility of any contamination between the layers which could create irregularities in the electrical field. By careful material selection and special attention to process parameters, we produce the insulation screen layers with the required degree of stripping force as stipulated by the applicable national or international standard.

Insulation

This will be an extruded layer of XLPE applied over conductor screen under triple extrusion process along with conductor screen and insulation screen.

Insulation Screen

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

Metallic Screen

It will consist of a layer of copper tape applied helically with overlap over insulation screen. Other combinations of metallic screens as per customer ’s requirement can also be provided on request.

Inner Sheath (Bedding) for Armoured Cables

Extruded layer of PVC or PE is applied over the laid up cores for armoured cables. PVC is normally of grade ST2 and PE of grade ST7 as per IEC 60502 Part 2.

Armouring

In case of armoured cables, the armour is applied helically over inner sheath. For single core cables, it is of aluminium wires and for multicore cables, the armour can be of one among the following options:

a) Galvanized steel wire.

b) Galvanized steel tape.

Over Sheath

An extruded layer is applied over the armour in case of armoured cables and over laid up cores in case of unarmoured cables. Outer sheath material can be either PVC, PE, HDPE or MDPE. our

medium voltage cables are normally supplied with red PVC over sheaths complying with BS 6622 or IEC 60502. Other colors may be provided to suit a range of installation considerations such as the effect of UV radiations and differing soil compositions. Anti-termite formulations can also be supplied in addition to graphite-coated over sheaths where on-site testing of the sheath is required
