AAC conductors
AAC
All Aluminum Conductor
Aluminum conductors reinforced with Class A galvanized steel core
Structure
All-aluminum conductors include wires of pure aluminum 1350 that are woven in one or more layers around a central wire with a round cross-section.
Each layer has 6 more strands than the previous layer.
Alumtek
The high flexibility of these conductors has caused the number of layers to increase in a certain cross section.
Alumtek
These conductors are generally designed with the number of strands 7, 19, 37, 61 and 91.
The direction of the outer layer in these conductors is clockwise and usually each layer is the opposite of the other layer.
Alumtek
These conductors are produced from pure aluminum wires with 1350 grade and H19 temper.

Application
AAC all-aluminum conductors, since they have low mechanical strength, very good electrical resistance, and high current carrying capacity, are mostly used in distribution lines and power transmission stations and in short spans.
These conductors are used in overhead power lines in situations where high strength or higher thermal tolerance compared to ACSS and ACSR conductors or other types of conductors are not part of the design parameters. take.
Features
AAC conductors are usually considered as conductors with:
light weight
easier movement in installation
reduction of complex fittings
high corrosion resistance
electrical resistance Low
high flow relative to the cross section
are known.
Reference standards
All aluminum conductors are produced and presented in accordance with the requirements of international standards ASTM B230, BS EN 50182, IEC61089.
