AAC (All Aluminium standard Conductors)
Standard conductors are the conductors made of thin wires of small cross-section and bunched together. They are made by twisting the wires, called the strands, together to form layers. The wires of each layer are laid in helical fashion round the preceding layer. The process is called "stranding".
1. AAC are flexible, not rigid and can be coiled easily.
2. AAC weights only half as the equivalent copper conductor and cost per unit length is considerably less.
3. They eliminate to a large extent the risk of breaking through insulation.
Uses: All aluminium stranded conductors are mainly used for low voltage distribution overhead lines having short spans of up to 65m.
