In the ABC system, the insulated aluminum conductors (3 or 4 numbers as required) are twisted around a high strength aluminum alloy bearer wire which covers the main weight and also serves as the earth cum neutral wire. The phase conductor is not under tension. Due to theft prevention, heights of pole elimination of insulator and associated hardware and the possibility of using small sizes of phase conductors like 16 sq. mm in certain location the overall cost of the ABC lines is practically the same as in conventional overhead lines. Our AB cables are manufactured as per national and international specifications and as per customer requirements. Due to various customers’ requirements the composition and designation of cables are different. Some designations are given on left side of the table mentioned below. The first part of the designation refers to the numbers and size of the phase conductor, the middle to the street light conductor (where provided) and last to the bare messenger wire. The sizes shown are the nominal cross sectional areas.
