OPGW Extra-Strength Double Helical Tension Set

Helical Tension Set is mainly used in optical cable installation on strain tower, angle tower and dead-end tower. The material of Helical Tension Set is aluminum-clad steel or galvanized steel wire which has excellent mechanical and electrical performance, to insure strong electrochemical corrosion and fatigue resistance. Grip strength of the Helical Tension Set is no less than 95% Rated Tensile Strength of the cable.

The installation of Helical Tension Set is simple, convenient and quickly, it is unnecessary to use any specialized tools, only one person can complete the operation, saving the time of construction greatly and increasing construction efficiency to reduce installation cost. The quality of installation can be examined by the naked eye, without any specialized training and special tools for installation inspection.

A complete set of Helical Tension Set is including Aluminum Alloy or Aluminum-Clad steel Dead-end, Structural Reinforcing Rods, Supporting fittings and Grounding wire Clamps etc.
