About the Cable

These cables consist of carbon and hydrogen compounds, which essentially contain low-density polyethylene molecules in the form of long flexible chains. On cross-linking, slippage between flexible chains can be prevented. Cross-linked polyethylene (XLPE) is a thermosetting compound. It softens at the crytahne melting point of polyethylene (85°C to 115°C) and assumes an elastic rubber like consistency, a property that it retains during further rise of temperature until it becomes carbonized without melting at 250°C to 300°C. All this strengthens LT-XLPE cables against stress cracking and gives them a greater resistance to fight ageing in hot air.

The advantages of LT XLPE cable are :

  • LT-XLPE Cables have longer life as compared to conventional PVC Cables.

  • LT-XLPE Cables have higher conductor temperature rating i.e, 90°C as against 70°C of PVC and hence higher current rating.

  • LT-XLPE Cables have higher emergency overload capacity than PVC Cables (upto 60%).

  • Max. temperature limit under short circuit conditions for LT-XLPE Cables is 250°C as against 160°C for PVC Cables. Hence XLPE cables have higher short circuit rating.

  • The moisture resistance of LT-XLPE Cables is nearly 100 times that of PVC.

  • Insulation resistance of LT-XLPE Cables is very high as compared to PVC Cables.

  • LT-XLPE Cables have high corrosion resistance in polluted atmosphere as compared to PVC Cables.

  • LT-XLPE Cables have better properties of resistance to chemical and corrosive gases.

  • LT-XLPE Cables have low installation cost because of light weight, dimensions and are far more flexible.

  • LT-XLPE Cables have better properties to withstand vibrations, hot impacts.

  • Jointing of LT-XLPE Cables is easier and quicker.

  • LT-XLPE Cables are ideal for transmission and distribution of power.

Application

Transmission lines with all the advantages of XLPE

General Construction
Conductor

Conductors are made from electrolytic grade aluminium/copper conforming to IS:8130, and are compact circular or compact shaped.

Insulation

Our XLPE cables are specially made high grade cross-linked polyethylene for insulation by extrusion process.

Laying up

In multi-core cables, cores are laid up as per the colour scheme, interstices are filled wherever necessary to make the laid up cores circular.

Inner Sheath

Laid up cores are bedded over with thermoplastic material for protection against mechanical and electrical damage.

Armouring

Armouring is provided over the inner sheath to guard against mechanical damage. Armouring is generally of galvanized steel wires or strips (In single core cables used in AC system armouring is by non-magnetic hard aluminum wires/strips). Round steel wires are used where the diameter over the inner sheath does not exceed 13mm. Above 13mm, flat steel strip armour is used. Round wire of different sizes can be provided against specific request.

Outer Sheath

Specially formulated heat resistant black PVC compound confirming to the requirement of Type ST-2 of IS:5831-1984, extruded to form the outer sheath.

Tests

In addition to all tests as required by IS:7098 Part-1, XLPE Cables are subjected to a number of in-house tests at every stage of production. Incoming raw material is also tested thoroughly to ensure consistency of quality.
