The pre-twisted tension clamp is intended to install the bare conductor or the overhead insulated conductor in transmission/transformation power line, which is more reliable and economic than the bolt/hydraulic tension clamp that now widely used.

The pre-twisted tension clamp is simple structurally. The tubular structure formed from the two pre-twisted wire legs, after installation, may wind around conductor naturally, generating great holding strength on conductor. New structure and fine design have conductor tension clamp owned reliable property. Clamp often is made up of aluminum clad steel, galvanized steel wire, etc.
