LT XLPE Aerial Bunched Cables

LT Cables
Available other colour as per customers’ requirement.




Phase or street lighting Conductor: hard drawn Aluminium H2 or H4 grade as per IS: 8130, Messenger conductor: Aluminium Silica and Magnesium Alloy used after treatment as per IS: 398 (Part4)


XLPE / PE applied by extrusion process.

Identification of Phases

By providing ridges on the insulation of phase conductors. One ridge for 1st phase, 2 and 3 ridges for 2nd and 3rd phases
respectively. Neutral can have 4 ridges, if desired.

Colour of Insulaiton

Because the cable remains exposed to environment & sunlight the insulation is mixed with a small amount of carbon black to stop deterioration of polyethylene due to UV radiation.


The phase conductor along with the lighting conductor (where applicable) is twisted around messenger conductor.


The phase conductor can be of single phase and also of three phases. Lighting conductor can be also incorporated to give supply to the street lighting. Messenger conductor supports the weight of the cable and keeps the assembly strung under tension. The phase conductor is made of concentrically stranded Aluminium wires having 7 or 19 wires. The messenger conductor is made of specially treated silica, Magnesium Aluminium alloy having 7 wires. The phase conductor and lighting conductor where applicable are insulated with XLPE / PE compound. The messenger conductor, as per customer’s choice is kept either bare or insulated. The phase conductor along with lighting conductor, where applicable is twisted around the messenger conductor. Sometimes as a special case a neutral conductor is also provided separately. Generally, messenger acts as neutral path.

This type of construction has the following additional advantages:

  • Cables are lighter in weight.
  • Easy to install.
  • Can be installed on poles, on walls etc.
  • Easy to make termination and branch off joints on live wire as well.
  • Protection against power theft.
