CICATM
About CICATM
Composite insulated cross arm (CICA) is composed of cable insulators, post insulators, metal coupling connection, voltage equalization shielding devices, and suspend fitting strings for conductors.
CICA (Composite insulated cross arm) replaces the combination of "traditional iron cross arm + hanging insulated string" in overhead transmission lines, and acts as an insulating support for high-voltage wires. It has more excellent electric insulation performance and mechanical performance than traditional solutions.
Solution advantage
The overall solution of CICA transmission line can specifically solve the pain points of existing power grids and new power grids.
The application of the CICA overall solution to newly-built transmission lines can significantly solve the problems with corridor width, large tower size, land acquisition, and high demolition costs. During the subsequent operation and maintenance, not only the problem of wind swing power skipping and insulator string breaking can be prevented, the probability of various flashover accidents can also be reduced. The operation and maintenance of external insulation in the whole life cycle can be guaranteed (≥30 years) as to ensure the lowest whole life cycle cost of the transmission line.
Applying the overall solution of CICA transmission line to upgrade existing transmission lines can not only solve the problem of wind swing tripping, but also significantly reduce the probability of other types of flashover accidents during the whole life cycle of the line. At the same time, the overall solution of CICA transmission line can realize the horizontal transformation of the corridor (reducing the corridor width), the vertical transformation of the corridor (raising the hanging point), the voltage boosting, the current increasing transformation, etc. It is the best choice for the upgrading of overhead transmission lines.
