Overview
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.

When the suspension clamp is used for aluminum stranded wire and steel core aluminum stranded wire, it can be wrapped with aluminum sheathing or protective wire to protect the wire. The applicable outer diameter of the wire includes wrappings.
