Aluminum Conductor Fiber Reinforced (ACFR)
The Aluminum Conductor Fiber Reinforced (ACFR) is manufactured by Kevin Vietnam Power Cable Co., Ltd.
The conductor is constructed using annealed trapezoidal aluminum strands (1350-O) with electrical conductivity exceeding 63% IACS.
The core consists of a composite structure made from carbon fibers and glass fibers, manufactured by Tokyo Rope Mfg. Co., Ltd..
The conductor has a continuous operating temperature of 180°C, and an emergency operating temperature of up to 200°C.
High-temperature conductor with carbon composite core is a type of electrical conductor designed to double the current-carrying capacity compared to conventional conductors. The trapezoidal-shaped aluminum strands significantly reduce electrical resistance, thereby enabling a 30–40% reduction in line losses compared to conventional conductors of the same diameter.
The conductive aluminum is fully annealed aluminum, combined with a carbon composite core featuring low thermal expansion, high tensile strength, and significantly lower weight than traditional steel cores. As a result, the conductor exhibits reduced sag, allowing for longer span lengths and lower tower heights, which in turn reduces both the number of towers required and their structural weight.
High-temperature, carbon composite core conductors provide an effective solution for uprating existing transmission lines by increasing current capacity, as well as for new line construction, enabling higher power transmission, longer span distances, and lower tower costs.
