These ABC Cables are knows as XLPE insulated Aerial Bunched Cables. These Cables Consists of 1 to 3 Nos. XLPE Cross Linked Polyethylene insulated phase Aluminum Conductor Cable Twisted around one no. Messenger conductor made from Aluminum Alloy and may be bare or insulated. These cables are now being used in LT Distribution Lines to avoid theft of electricity.
Aerial Bunched Cables For Overhead Distribution:
Aerial bunched Cable (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.
ABC is also considered to be the best choice for power distribution in congested urban areas with narrow lanes and by-lanes. In developing urban complex, ABC is the better choice because of flexibility for rerouting as demanded by changes in urban development plan.
Applications: ABC can be conveniently used:

Applications: ABC can be conveniently used:
- As replacement of bare lines in rural areas, in woods and in other localities & narrow Streets where the space is 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 faults by high winds or falling trees or birds especially in hilly areas & forests as encountered in rural distribution net-works.
- 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 over-head bare conductor system without any interference.
- High capacitance and low inductance leading to low impedance of lines.
- Lower voltage drop, higher current capacities, VlS-A-VlS Better Voltage Regulation.
- Longer spans and longer distance lines are possible with better system stability.
