All Aluminium Conductor (AAC)
Concentric lay stranded Aluminum Conductor ( AAC) is comprised of at least one strands of hard drawn 1350 aluminum alloy. These conductors are utilized in low, medium and high voltage overhead lines. AAC has seen broad use in urban regions where ranges are generally short however high conductivity is vital. The superb consumption opposition of aluminum has settled on AAC a conductor of decision in waterfront territories. On account of its generally poor solidarity to weight proportion, AAC had restricted use in transmission lines and rural distribution as a result of long traverses used
An aluminum wire have a 1.5 times larger cross section to pass indistinguishable current from a copper wire, however multiple times lighter. Weight is a standout amongst the most vital parameters for high-voltage electrical cables that transmit power over extended distances. Along these lines, just aluminum wires are utilized in primary overhead electrical cables.
Bare all aluminum conductors (AAC) are concentric-lay-stranded comprising of not leass than one layer of aluminum composite 1350 wires wrapped helically around a focal wire. Each progressive layer has six wires more than the basic one. Expanding the number of wires for some random cross-sectional region gives more prominent adaptability. The most generally utilized strandings comprise of 7, 19, 37, 61 and 91 wires.
AAC conductors are the most efficient since their lighter weight implies lower unit length costs, less demanding to take care of amid establishment and the utilization of more straightforward fittings. They are intrinsically corrosion safe because of their homogeneous development.
- high Current Carrying Capacity
- excellent resistance to corrosion
- Ideal for use in coastal area
- suitable for low & medium voltage lines in urban area
