Huaneng vibration dampers are mainly incorporated with hot-dip galvanized cast iron heads, hot-dip galvanized steel armor rods, aluminum alloy clamp, and stainless steel bolt. Typical damper design whose principle is absorbing energy dynamically and keeping the frequency at 6Hz-150Hz is employed for this vibration damper. There will be 4 resonant frequencies available within this frequency range thus the vibration caused from any factors during cable running will be validly avoided.

Since 2002, Huaneng has been at the forefront of the electric power fittings industry. Our specialized expertise lies in the production of a complete selection of preformed line products, covering conducting wires, earth wires, overhead power ground wires (OPGW) and all dielectric self-supporting (ADSS) cables.
