ACCC® conductor consists of fully-annealed, trapezoidal-shaped aluminum strands that are helically wrapped around a carbon and glass fiber composite core. The composite core is manufactured through the use of a proprietary pultrusion process, where the glass fibers and carbon fibers are impregnated with a thermo-set epoxy resin and pulled through a multi-stage curing die to create the finished core. The core is produced to ISO 9001:2000 standards in lengths of up to 24,000 feet. The finished core is then fully tested to stringent ISO certified quality assurance standards, placed on reels, palletized, and shipped to licensed stranding companies world-wide. Currently, over ten core sizes are produced by CTC Cable. ACCC® conductor’s composite core is manufactured exclusively by CTC Cable at its manufacturing plant in Southern California.
The licensed stranding companies feed ACCC® composite core into stranding machines that apply various layers of aluminum wire strands around the core to create the finished conductor. ACCC® conductor’s aluminum strands are made into trapezoidal wire, and then annealed before the aluminum wires are stranded onto the core to produce ACCC® conductor. The number of strands, strand size, and number of strand layers depends upon the finished conductor’s design and size. Twenty-five sizes of finished conductor are currently being produced in North America, Europe, the Middle East, China, and Indonesia.
