Aerial Bundled Cable (ABC) is designed for residential and rural areas for reducing the bushfire hazards. Aerial Bunched Cables is a very novel concept for Over Head Power distribution when compared to the conventional bare conductor over-head distribution system. ABC provides higher safety and reliability, lower power losses and ultimate system economy by reducing installation, maintenance and operative cost. This system is ideal for rural distribution and especially attractive for installation in difficult terrains such as hilly areas, forest areas, coastal areas etc.
Aerial Bunched Cables is also considered to be the best choice for power distribution congested urban areas with narrow lanes and by – lanes. In developing urban complex, Aerial Bunched Cables is the better choice because of flexibility for rerouting as demanded by changes in urban development plan.
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 Aluminium Alloy having 7 or 19 wires.
Phase and lighting conductors may be insulated with XLPE compound using Sioplas Technology. Messenger conductors are kept either bare or insulated. Phase and lighting conductors are twisted around the messenger conductor. In special cases a neutral conductor and a street light cable may also be provided separately. Generally, the messenger acts as earth and neutral.
HT Cables designed to be used underground directly, buried in ducts, trenches or in tunnels for electric power transmission at high voltage, finds its applications in :-
• Transmission of Power from 3.3kv to 33 KV
• For power distribution by utilities to residential, commercial complexes & Industries consuming bulk power.
• For Large & Medium industries where equipment’s require power at high voltage
• Solar & Thermal Power Plants
Single Phase or Three Phase systems with or without Neutral Conductor and Street Light line.
XLPE with Sioplas Technique.
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.
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.
