Helical Tension Set is mainly used in optical cable installation on strain tower, angle tower and dead-end tower.

• Product process

• 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.

   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.

  Product advantage

• 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.

• PGW Helical Tension Set

• 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

• 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. 

  
  

  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. 

   

  

• Short Span ADSS Tension Set

• The material for Short Span ADSS Tension Set is aluminum-clad steel and galvanized steel wire; it is mainly used for ADSS installation between strain tower/pole, corner tower/pole, mid-joint tower/pole and terminal tower/pole which span length is less than 100m.

   

  

• Medium/Long Span ADSS Tension Set

• Medium/Long Span ADSS Tension Set is composed of Dead-end component and structural reinforcing rods, the materials are aluminum-clad steel and galvanized steel wire, it is mainly used for ADSS installation between strain tower/pole, corner tower/pole and terminal tower/pole which span length is larger than 200m with RTS of the cable is larger than 15kN. Medium Span ADSS Tension set is used for installation span length between 200m-400m, Long Span ADSS Tension set is used for installation span length longer than 400m.

   

  

• OPPC Helical Tension Set

• OPPC Helical Tension Set is composed of Dead-end components, Structural Reinforcing Rods, Thimble Clevis etc. OPPC Helical Tension Set is installed onto the tower/pole through insulators.
