Aerial Bunched Cables (ABC) 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 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.

Types Of A B Cables:

• LOW VOLTAGE ABC (LV) :
•  
• Application:
• In electricity theft prone areas
• As replacement of bare lines where reliabilities of support is of prime importance
• As reinforcement of existing system with increase in voltage/current carrying capacity
• For temporary supplies
• As replacement of bare lines in rural are & narrow street with limited space
• In hilly terrain here cost of erection of overhead lines or under ground cable becomes very high
• As replacement of bare lines where reliabilities of support is of prime importance

•  
• MEDIUM VOLTAGE ABC (MV):
•  
• Application: 
• In electricity theft prone areas
• As placement of bare lines where reliabilities of power supply is of prime importance
• As reinforcement of existing system with increase in voltage/current carrying capacity
• As placement of bare lines in rural areas & narrow streets with limited space

In hilly terrains where cost of erection of overhead lines or underground cable becomes very high
