1.1 KV Volt Grade, are used for distributing power to individual consumers by utility service

providers such as electricity boards and electricity distributing authorities. The cables are

suspended overhead using electrical poles. The cables can be tapped intermittently from any

required position, enabling them to be used in urban as well as rural areas.

Configuration

Single Phase or Three Phase systems with or without Street Light line.

Conductor

Phase or lighting conductor: Electrical grade Aluminium of H2 or H4 grade as per IS: 8130

Messenger conductor: Aluminium Silica and Magnesium Alloy.

Insulation

XLPE with Sioplas Technique.

Identification of Phase

Ridges provided on the insulation of Phase Conductors: 1 ridge for the 1st phase, 2 ridges for

the 2nd phase and 3 ridges for the 3rd phase. The Neutral phase may have 4 ridges if required.

Colour of Insulation

As the cable remains exposed to environmental elements such as UV rays from sunlight, the

insulation is mixed with a small amount of carbon black to prevent the deterioration of

polythene.

Construction of Cable

The phase conductor can be of single phase or three phases. A lighting conductor can be also

incorporated for street lighting. A messenger conductor supports the weight of the cable and

keeps the assembly strung under tension. Phase conductors are made of concentrically

stranded Aluminium Wires having 7 or 19 wires. Messenger conductors are made of a specially

treated Silica, Magnesium and Aluminium Alloy having 7 or 19 wires. Phase and lighting

conductors may be insulated with XLPE compound of Sioplas Technology. Messenger

conductors are kept either bare or insulated. Phase and lighting conductors are sometimes

twisted around the messenger conductor. In special cases a neutral conductor may also be

provided separately. Generally, the messenger acts as earth and neutral.

This construction has additional advantages

Cables are lighter in weight

Easy to install

Can be installed on poles, on walls etc.

Easy to make terminations and branch off joints on live wire as well

Protection against power theft
