Cable structure
- Conductor material: In AAC cables the strands of hard drawn aluminium conductors are twisted together with controlled lay length to form a good construction and to withstand tensile forces when installed in the line
- In ACSR cables the strands of hard drawn aluminium conductors are twisted around a central galvanized high carbon steel wire(s) to withstand more tensile forces
Application
AAC: These types of cables are used for distribution of electrical power in low and medium voltage lines where the masts are close to each other.
AAAC and ACSR: These types of cables are used for distribution of electrical power in medium and high voltage lines where the masts are far away from each other.
