English
- OPGW Helical Tension Set is mainly used for installation of cable with less than 160kN RTS onto tension tower/pole, corner tower/pole, and terminal tower/pole. A complete set of OPGW Helical Tension Set includes Aluminum Alloy or Aluminum-Clad steel Dead-end, Structural Reinforcing Rods, Supporting fittings and Grounding wire Clamps etc.
- OPGW Extra-Strength Double Helical Tension Set is special designed for cable installation on large span, high fall and big corner over head line, where the cable RTS is larger than 160kN.
Helical Tension Set for OPGW
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.

Characteristics
- 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.
- It is composed of three layers construction, including inner reinforcing rods, structural reinforcing rods and outer layer Dead-ends. This structure improves the tensile strength of Helical Tension set, without restriction such as line turn-angle. A complete set of OPGW Extra-Strength Double Helical Tension Set includes helical rods, link fittings and Grounding Clamps etc.
