Introduction of ACCC Conductors
In particular, ACCC conductors have been used to increase the efficiency of the re-conductor portion of the transmission grid by 30% or more.
ACCC cables use lightweight, small size carbon fiber composite cores. It not only increases the load-bearing capacity of the overall material but also reduces the core volume of the new ACCC cable. ACCC cables can provide double the power of ordinary traditional cables, and can effectively solve the problem of cable sag caused by high temperature.
While aluminum strands are fully annealed to provide the highest degree of electrical conductivity of any aluminum material available today, the composite core material has a coefficient of thermal expansion that is approximately ten times that of steel.
Application of ACCC Conductors
ACCC aluminum conductor composite core is the latest type of stranded conductor, which is mostly used in overhead transmission lines. Under the same conditions, it has twice the capacity of ACSR.
ACCC conductors feature a hybrid carbon fiber and glass fiber core embedded in a high-performance epoxy matrix. The central carbon-fiber core consists of tens of thousands of high-strength, high-modulus unidirectional carbon fibers surrounded by a protective glass fiber layer. The outer layer of fiberglass increases toughness and flexibility while also providing a barrier to electrical current.
ACCC conductor hybrid core is not only twice as strong as steel but 70% lighter. The lighter weight allows ACCC conductors to use approximately 28% more aluminum without adding weight or diameter.
Advantages of ACCC Conductors
Compared with the same diameter ACSR cable, it can provide double the current carrying capacity. Effectively solve the problem of cable snagging. They can work at higher temperatures up to 200 degrees Celsius. And the core is corrosion resistant and there are no bi-metallic corrosion problems. Because it can provide higher current-carrying capacity, it also effectively reduces engineering costs.
Holds 28% more conductors than conventional cables of the same diameter. High-strength wire cores can effectively reduce the number of cable racks, or reduce the height of cable racks. And effectively reduce cable sagging, making ground creatures safer.
ACCC cable technology allows transmission companies, power companies, and power plants to simply replace the corresponding transmission lines, without the need for special installation skills and equipment, and without the need to modify cable racks. Aluminum conductor steel core (ACSR) and other traditional transmission cables use a steel wire core, largely based on a traditional 1898 design.
