C-type clips are wire-connection type power connection fittings, which are mainly used for T-connection or jumper wire at the non-load-bearing position of overhead insulated wire, steel-cored aluminum stranded wire, aluminum stranded wire, steel stranded wire and copper wire. The wire clip is made of high-strength special aluminum alloy with good electrical conductivity, and the structure is composed of reasonable C-shaped and hinged wedges. between. When the wire is thermally expanded and contracted, the C-type structure should have the flexibility to always ensure a lasting and constant contact pressure between the wire clip and the wire. It changes with the external environment and load conditions, and the contact pressure remains unchanged, which meets the best requirements for continuous connection.
