Advantages of Low Voltage Aerial Bundled Cables for Overhead Power Distribution

AB Cable

Table of Contents

Aerial Bundled Cable is an innovative concept for Over Head (OH) power distribution. The Low Voltage Cable plays a crucial role here. When compared to the conventional bare conductor OH distribution system, ABC provides higher safety and reliability, lower power losses, stability in voltage regulation and ultimate system economy by reducing installation, maintenance and operation cost.

Easy & Safe Installation in Difficult Terrain:

This system is ideal for rural distribution and especially attractive for installation in difficult terrain such as hilly areas, dense forests, coastal regions etc. These lines can be laid without cutting or trimming any trees. ABC is also considered to be the best choice for power Distribution in congested urban areas with narrow lanes and by-lanes. It is convenient to lay even in densely populated areas with narrow gaps between buildings, where it is usually not possible to run bare conductors. Additionally, accidental electrocutions are avoided by the insulation of the cable. The insulated system also allows live line working which means less downtime and a safe working environment which leads to quick installation.

Cost-Effectiveness of Low Voltage Aerial Bundled Cable:

Underground cable installations have a capital cost ratio as high as 20:1 when compared to OH lines, thus giving the ABC system a distinct advantage in cost-effectiveness. Also, since the cables are clearly visible, the faults can be detected and rectified quickly and with ease. Damage due to waterlogging is also avoided as compared to underground cables.

Low Voltage Aerial Bundled Cable is reliable:

ABC’s are highly reliable and the insulation has been developed to withstand heat, cold and intense sunlight. Disturbance and faults occur five to ten times more on open-wire lines than on ABC lines. There is no risk in working on a live cable and the insulation reduces the number of short circuits, over-voltages and transformer burnouts caused by thunderstorms. Fewer hardware accessories are needed as each one can be used with many different sizes of cable. Since the cable will be supplied with conductors for street lighting, it is more cost-effective.

Reduced Distribution Losses:

According to World Bank analysis, India loses 20% of its generated electricity due to T&D losses of which power theft is a major component. Compared to the bare line system, the insulation of the ABC system makes it far more secure and thus saves it from Power Theft.
