Which one of the following statement with respect to Aerial Bunched Cables (ABC) system is TRUE?

• A. The overall cost of the ABC system is very high as compared to the bare conductor system.
• B. ABC system is not suitable for rural electrification which are situated in difficult terrain, hills, forests and coastal areas.
• C. ABC system requires more clearance, insulators and high maintenance.
• D. ABC system totally eliminates the fault on lines and thereby improving the quality of supply.

Answer: (D)

Aerial bundled cables/conductors are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor.
This contrasts with the traditional practice of using uninsulated conductors separated by air gaps.
This variation of bundled conductors utilizes the same principles as overhead power lines, except that they are closer together to the point of touching but each conductor is surrounded by an insulating layer
