Low Voltage XLPE Cables are manufactured according to IS:7098 (Part -I), up to and including the latest amendments. All cables have the ISI Certification.

XLPE, as insulation has the following superior features:

• Low dielectric loss.

• Higher power rating and higher emergency overload rating.

• Superior short circuit rating.

• Much better insulation resistance

• Higher resistance to moisture

• Capacity to withstand localized hot spot temperature, very vital to steel plants,

power stations, etc.

• Resistant to chemicals and corrosive gases, etc.

• Exhibits better properties, such as resistance to vibration, impact, aging, and hot deformation.

• Termination and jointing methods are very easy, simple, and non-expensive as compared to

other cables.

DESIGN AND CONSTRUCTION

CONDUCTORS

The conductors of power cables are made from electrical purity aluminum, and those of control cables are of annealed high conductivity copper. However, copper conductor power cables can also be supplied against orders. All conductors conform to IS:8130-1984.

INSULATION

A High-quality Cross-Linked Polyethylene (XLPE) unfilled insulating compound is used for XLPE Cables.

INNER SHEATH

For all cables having two or more cores, a common covering (inner sheath) is applied over the laid-up cores either by an extruded sheath of PVC Compound or wrapping of thermoplastic or proofed tapes.

ARMOURING

For multi-core cables, armor is applied over the inner sheath. In the case of cables where the fictitious diameter over the inner sheath does not exceed 13mm., the armor consists of galvanized round steel wires; above this size, normally the armor is of galvanized formed steel wires. Any metallic, non-metallic wire/strip can be available on request.

OUTER SHEATH

The outer sheath is extruded over the armoring. Outer sheath PVC is Antirodent, Antitermite, and Ultra Violet resistant. In the case of multi-core unarmoured cables, over the inner sheath, whereas, in the case of unarmoured single-core cables, it is extruded over the insulation. This is always black in color for best resistance to outdoor exposure. Any other color can be available on request.
