The LT/LV AB cables (aerial bunched) cable is a very novel concept in overhead power distribution, as compared with conventional bare conductor in overhead distribution system, AB cables provides higher safety, reliability, lower power losses and ultimate economy by reducing installation, maintenance and operative cost. This superior system is ideal for rural distribution and especially attractive for installation in difficult terrains such as highly areas, forest areas, coastal areas etc. These cables are designed, manufactured & tested conforming to IS: 14255 & other international specifications. AB cables is also considered as choice for power distribution in congested urban areas in developing urban complex AB cables is a better choice because of its flexibility for re-routing as demanded by changes in urban development plan.
Less fault rate on account of good protection against line and ground faults by high winding falling trees or birds especially in hilly areas and forests.
High insulation resistance to earth in all seasons. Negligible leakage currents and low losses.
Multiplexer circuits of power and telephone cables could be in the same set of poles.
Better adaptability to lay besides 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 carrying capacities vis-à-vis better voltage regulations.
Longer spans and longer distance lines are possible with better system stability.
AB cables are much safer than bare conductors.
It can be laid in dense vegetation and forest areas.
Additional connections can be easily and quickly made with hot line connectors.
Overall lines cost is reduced.
Maintenance is very convenient.
Very difficult to tap the AB cables, thus reducing theft which leads to lower distribution losses.
