Aluminum Conductor Steel Reinforced (ACSR) and other traditional energy cables utilize a steel wire core around which the aluminum conductor wires are wrapped – a design originally introduced in 1898. In contrast, CTC’s Aluminum Conductor Composite Core – ACCC – cables incorporate a light-weight advanced composite core around which aluminum conductor wires are wrapped in a manner identical to traditional energy cable. The composite cores lighter-weight, smaller size, and enhanced strength and other performance advantages over traditional steel core allows ACCC to double the current carrying capacity over existing transmission and distribution cable and virtually eliminate high-temperature sag.
