AAAC – 6201 All aluminum alloy conductor

 

AAC, AAAC, ACSR

These aerial cables consist of separate conductors which use spacing between conductors to obtain a voltage rating. There are three major types of aerial conductors used for electrical transmission and distribution.

 

The choice of conductor is determined by current rating and stringing conditions (span length, sag, everyday stress, ambient temperature and wind velocity, and worst case conditions of wind and ice). Conductor characteristics such as strength to weight ratio, ultimate tensile strength, modulus of elasticity, area, coefficient of linear expansion, AC resistance will determinethe most suitable conductor.

 

AAC – All Aluminium Conductor is made up of one or more strands of hard drawn 1350 Aluminium Alloy. Because of its relatively poor strength-to-weightratio, AAC has had limited use in transmission lines and rural distribution because of the long spans utilized. However, AAC has seen extensive use in urban areas where spans are usually short but high conductivity is required. The excellent corrosion resistance of aluminium has made AAC a conductor of choice in coastal areas.

 

ACSR – Aluminium Conductor Steel Reinforced consists of a solid or stranded steel core surrounded by one or more layers of strands of 1350 aluminium. The high-strength ACSR 8/1, 12/7 and 16/19 strandings, are used mostly for overhead ground wires, extra long spans, river crossings, etc. The inner core wires of ACSR may be of zinc coated (galvanized) steel.

 

AAAC(1120) – A high strength Aluminium-Magnesium-Silicon Alloy cable was developed to replace the high strength 6/1 ACSR conductors. This alloy conductor offers excellent electrical characteristics, excellent sag-tension characteristics and superior corrosion resistance to that of ACSR.

 

Equivalent aluminum alloy conductors have approximately the same ampacity and strength as their ACSR counterparts with a much improved strength-to-weight ratio,and also exhibit substantially better electrical loss characteristics than their equivalent single layer ACSR constructions. The thermal coefficient of expansion is greater than that of ACSR.

 

As compared to ACSR, AAAC's ligher weight, comparable strength and current carrying capacity, lower electrical losses and superior corrosion resistance have given this conductor wide acceptance as a distribution conductor. It hasfound limited use, however, as at ransmission conductor.

 

AERIAL AAAC/1120

Application: 7 and 19 strand construction is suitable for bare overhead reticulation of medium spans, normally at low and medium voltages.

                     37 and 61 strand construction is suitable for transmission and subtransmission lines where homogeneous construction can reduce line losses and improve corrosion resistance in conductors with similar strength to.

 

AERIAL AAAC/1350

Application: 7 and 19 strand construction is suitable for bare overhead reticulation of medium spans, normally at low and medium voltages.

                     37 and 61 strand construction is suitable for transmission and subtransmission lines for short span projects.  Also used as flexible bus bar.
