Description:

Preformed spacer uses pre-stranded wire as the connection structure between spacer bar clamp and protected wire, so it has the advantages of convenient and fast installation of pre-stranded metal fittings, good grip on wire (avoiding the loosening of wire clamp caused by thermal expansion and cold contraction), even grip without damaging wire, no hidden danger of bolt loosening (maintenance-free), good corona prevention and energy saving. Pre-twisted wire and clamp are made of aluminum alloy, and have excellent fatigue resistance.

It has proven to be excellent and widely used in decades of power lines in developed countries.CHINA-GRID POWER TECHNOLOGY CO.,LTD. overcomes technical difficulties and succeeds in production and refers to production. It has been tested and superior by authoritative organizations and has been put on the market and recognized by users.
