Tension Clamp are designed to connect OPGW cables and tensile poles (or towers). Armor rods can protect and provide cushioning to the OPGW cables. The special design of Armor rods makes ensure that Tension Clamps can not cause undue stress to the OPGW cables, so that the normal lifetime of cable system is ensured.
Structure and Material:
Shackle ---------Hot dip galvanized steel. Shackle is connected with fastening clamp on tensile pole (or tower).
Parallel Plate------ Hot dip galvanized steel. Parallel Plate is connected Thimble and U-shackle.
Thimble------------ Hot galvanized cast steel. Thimble is plugged in bend of Preformed Dead End for protection and connected.
Armor Rods-------Armor Rods are made of aluminum clad steel wires. With a layer of particle emery inside, Armor Rods can increase friction to cable. Rods are made into four subsets which can reduce misalignment errors and speeds installation. The ends are bent outward to avoid stress to OPGW cables.
Preformed Dead End---Aluminum clad steel wire. Preformed Dead End are made into one subset with a layer of firm emery inside, in order to increase gripping strength of Tension Clamp while decreasing side pressure.
1. It is designed to connect Terminal pole (tower), tensile pole (tower) and Continue pole (or tower). The special specification: one unit per Terminal pole (tower), two units per tensile pole (tower) and two units per Continue pole (tower).
2. Select the Specification Model for Tension Clamp corresponding to the cable diameter range and Rated Tensile Strength.
3. Ground Clamps are sold together with Tension Clamps, and prohibited directly installing on the Preformed Dead End and Armor Rods.
