Description:
Suspension clamps are mainly used for overhead power lines. Wires are suspended from insulators or lightning conductors are suspended from pole towers through connection fittings.
Traditional malleable cast iron clamps have the disadvantages of large hysteresis loss, large hole current loss, and bulky products. The aluminum alloy clamp has the advantages of extremely small hysteresis loss and eddy current loss, light weight, and convenient construction. It meets the requirements of energy saving and consumption reduction in the national power grid transformation and construction.
CGF corona-proof type suspension clamp adopts anti-halo design, especially suitable for 110KV and above lines. The clamp body and pressure plate are made of high-strength aluminum alloy, and have undergone heat treatment process, no hysteresis effect, and energy saving.
