SMAREPC—Technical advantages

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 and mechanical performance than traditional solutions which can significantly reduce the cost of construction of the line and the cost of operation & maintenance throughout the life cycle, making the line safer.

What solutions
can we provide you?


Our solution can eliminate operational reliability problems as flashover of external insulation, brittle failure, explosion, and others. Save construction costs, and enable for safer, more economical, and more environmentally friendly transmission and distribution of electric energy. Further, make the external insulation maintenance-free during the entire life cycle.
