Aerial Bundled Cable (ABC cable) has characters of power-transmitting and strong mechanical. In comparison with bare wire, aerial bundled cable (ABC cable) boasts many advantages, such as: small span in laying, higher safe reliability, better atmosphere aging resistence property. Aerial bundled cable has the priority to be used in urban and rural power-transmitting construction project.

Advantages

In comparison to bare overhead distribution lines, ABC Cables have very high reliability during the services. As the power and neutral conductors are insulated with the best dielectric material, 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 polluted atmosphere. Negligible 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 over-head 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-a-vis better Voltage Regulation

Longer spans and longer distance lines are possible with better systems stability

ABC Cables are much safer then 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 costs are reduced

Very difficult to tap the AB cables, thus reducing theft which leads to lower distribution loses
