The ACCC conductor is a carbon fiber core conductor. It's a new kind of driver for airlines of transmission. This type of cable is light, stretch resistant, thermally stable and corrosion resistant. It is especially suitable for use in coastal areas, mining areas and other corrosive environments where the driver is prone to dancing.
Conductive ACCCs can meet the requirements for construction of power grids that are resource-saving and environmentally friendly. ACCC cables are a new product that replaces the traditional ACSR and AAC conductors in electrical systems around the world..
Advantages of ACCC Drivers
High Strength and Light Weight
The tensile strength of ordinary steel wire is 1240-1410 Mpa. While, ACCC's carbon fiber core has twice the tensile strength of steel wire and weighs only a quarter. And ACCC conductors of the same size weigh between a 10% and a 20% less per unit length than conventional ACSR conductors. This makes it possible to reduce the number of towers by about one 16%, while reducing its footprint on the land..
High Electrical Conductivity and Low Transmission Losses
The cross-sectional area of the ACCC aluminum stranded conductors is 1,29 times greater than that of conventional cable conductors. Conductive ACCCs do not suffer the magnetic losses caused by the steel material or the thermal effects of electricity. As a result, has a lower operating temperature for the same load and reduces transmission losses around the 6%.
ACCC also has a smoother appearance than ACSR round aluminum cable due to the trapezoidal shape.. Besides, this improves the roughness of the cable surface and thus reduces corona losses.
Low Bow Collapse
ACCC conductors have significantly less arc sag compared to conventional cable conductors. This reduces the insulation space of the overhead line and increases the safety and reliability of the conductor's operation..
Corrosion Resistant
ACSR's aluminum wire and steel core are exposed to air for long periods of time. As a result, the surrounding environment can corrode the metal material.
ACCC's composite carbon fiber core is non-rusting and corrosion resistant. ACCC overcomes the corrosion problems of stranded wires galvanized steel. It also prevents galvanic corrosion problems between aluminum wires and galvanized steel wires.. How best to solve the problem of aging overhead conductors in long-term operation, its service life is twice that of ordinary cables.
