Aerial Bunched Cable

The phase conductor and neutralstreet lighting conductors is of H2 or H4 grade aluminium complying with the requirements of IS 8130:1984 and conforms to flexibility class 2 of IS 8130:1984. The size of the street lighting conductor is16 mm2.
Safest system because phase conductors are insulated, no risk of danger of accidental touching live conductor.
Less fault rage on account of good protection against line and ground fault by high winds or falling trees or bird 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.
