The pre-twisted spacer rod uses pre-twisted wire as the connection structure between the spacer rod clamp and the protected conductor. It has easy and fast installation, good grip on the conductor (avoid loosening of the clamp caused by thermal expansion and contraction), uniform grip without hurting the conductor, No hidden danger of loose bolts (maintenance-free), good anti-halo, energy saving (pre-stranded wire and clamp are made of aluminum alloy), superior fatigue resistance and other advantages.

It has been proved to be excellent and widely used in decades of operation on power lines in developed countries. CHINET has overcome technical difficulties, successfully and mass-produced products, and has superior performance tested by authoritative institutions.
