The tension assemblies in Huaneng are available both for OPGW and ADSS cables. They are mainly consisted of inner preformed wires, outer preformed wires, ferrule, PD clevis and U-clevis. Since our preformed tension clamps perform well in gripping the cables and bearing large tensile within the allowable strength of the fiber optic cables, a high safety degree can be guaranteed. Special treatment has been given upon the end of tension assemblies used on ADSS cables to prevent them from scraping the cable casing.

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.
