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 specially 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.
APPLICATION:
Aerial Bunched Cables can be conveniently used:
As replacement of bare lines in Rural Areas, in woods and in other localities & narrows
streets where the space limited.
As replacement of bare lines where reliability of supply is of prime importance.
As replacement of bare lines where high degree of stability of supply voltage is of
importance.
In hilly terrains where cost of erection of overhead lines or under ground cable becomes
very high.
As reinforcement of existing system without increasing voltage.
For temporary supplies.
ADVANTAGES:
In comparison to bare overhead power distribution lines, ABC has very high reliability in
maintaining services because power and neutral conductors are insulated with the best
dielectric medium, resulting in the following advantages:
Less fault rate on account of good protection against line and ground fault by high winds or
falling trees or birds especially in hilly areas & forests as encountered in rural
distribution networks.
High insulation resistance to earth in all seasons and polluted atmospheres. Negligible
leakage currents and low losses.
Multiple circuits of Power and Telephone cables could be strung in the same set of poles or
any other supports like walls etc.
Better adaptability to run concurrently with existing overhead bare conductor system without
any interference.
High capacitance and low inductance leading to low impedance of lines.
Lower voltage drop, higher current capacities. VIS-à-VIS Better Voltage Regulation.
Longer spans and longer distance lines are possible with better system stability.
ABC cables are much safer than bare Conductors.
It can be over hung in dense vegetation and forests.
Additional connections can be easily and quickly made with hot – line connectors.
Total lines costs are reduced.
Maintenance is very easy.
