AERIAL Cables

Orientcab Aerial Baunched Cable : 1100 volt grade Stranded & compacted Aluminium Phase Conductor, and Stranded Messenger Conductor with all aluminium Alloy, Phase Conductor is insulated with XLPE Compound, Messenger is either insulated or or bare. Referred specification IS : 14255- 1995 up to the latest amendment.

Ariel Bunched Cables, 1100 volt Grade, are used for distributing power to individual consumers by utility service providers like electricity Boards, electricity distributing authorities. The cable is kept supported on poles. The line is tapped intermittently from any required position which enables to be used in urban as well as rural areas alike.
Configuration : Multi-core/Multi-pair. 

Conductor
Phase or 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 (part 4).

Insulation
XLPE applied by extrusion process.

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

Color of Insulation
Because the cable remains exposed to environment & sunlight (ultraviolet radiation) the insulation is mixed with a small amount of carbon black to stop deterioration of polythene due to U V radiation.

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

Construction
The phase conductor can be of single phase and also of three phases. A 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 (made of Sioplas Technology) compound. The messenger conductor, as per customer's choice is kept either bare or insulated. The phase conductor along with lighting conductor (where applicable) are twisted around the messenger conductor (insulated or bare) and left as such. Sometimes as a special case a neutral conductor is also provided separately, if desired, by the user. Generally, messenger acts as earth as well as neutral.
