Aerial Bunch Cables, 1. 1KV 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 it to be used in urban as well as rural areas alike.
|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 with Sioplas Technique 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.|
