Overview
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.
The clamp body and pressure plate of the CGH aluminum alloy envolope-type overhanging clamp are made of high-strength aluminum alloy and have undergone heat treatment process. There is no hysteresis effect and it has energy saving effects. It is recommended to replace the high energy consumption XGU series malleable cast iron suspension clamps.
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.
XTS & CTS type suspension clamps for twin jumper conductor are adopted melleable iron casting & aluminum alloy, respectively. They are especially suitable for more than 110KV overhead transimission line; after thermal treatment, they are of hysteresis-free & energy-saving efficiency.
The energy-saving products developed by our company have passed the inspection of the Quality Inspection and Testing Center of the Ministry of Electric Power Industry, meet the requirements of GB2314 and relevant standards, and have passed the national energy-saving certification.
