1. Introduction  ACCC Conductor consists of composite core and annealed aluminumformed wires outer layer. The annealed aluminum formed wires outer layer anditsadjacent layer are trapezoidal crosssection. CFCC is a kind of carbonfiber product with high performance. Compared with the traditional aluminumconductors steel reinforced, it has series ofadvantages including high heat resistance, high current carrying capacity, hightensile strength, light weight, low-sag, saving costs of towers and poles anddecreasing the covering area etc.

4.Increased Power Transfer

When compared to an ACSR that can be strung on the same towers, ACCC conductors will carry about 28% more annealed aluminum in a trapezoidal configuration giving greatly increased conductivity; the carbon core provides increased strength and virtually eliminates high temperature sag allowing more efficient operation at up to 180°C. This can double current capacity (ampacity) over the ACSR.

5.Reduced High Temperature Sag

The coefficient of thermal expansion of ACCC conductor at its final condition is eight times less than typical ACSR, and the ACCC core is approximately two and a half times lighter than steel. ACCC conductors sag very little due to thermal expansion which eliminates this as a significant design consideration.

6.Energy Efficiency

Using more aluminum with better conductivity reduces losses at every temperature of operation. When operating as a High Temperature Low Sag (HTLS) conductor, the higher operating efficiency can reduce line losses and their associated emissions by more than 35%. This results in more power delivered to be sold and can result in lower power generation costs.

Lower initial sag at normal tensioning allows for lowering initial tensions on weaker towers and during line upratings or allows designing for smaller power towers on new lines.
