OPGW Optical Cable Tension Fitting StringFeatures:a. Even stress distribution, no stress concentration point, can well protect the optical cable.b. Under the premise of not exceeding the lateral compression strength of the optical cable, it has a greater grip on the optical cable and can withstand greater tension.c. The grip strength of the optical cable is not less than: 95% of the ultimate tensile strength (UTS) of the optical cable, which is completely suitable for the needs of optical cable erection.

Preformed inner protection line rods:The material is aluminum-clad steel wire, which is the same material as all the aluminum-clad steel wires of OPPC cable. The inner wall of the protector rods is glued with a layer of gold steel sand through a high-strength polymer water-soluble environmentally friendly adhesive to increase the friction with the optical cable. The rods is preformed into four sub-bundles during production, which is convenient for quick installation.

The grounding clamp is mainly used for the grounding of the OPGW optical cable to provide a path for short-circuit current. The grounding clamp consists of a grounding wire, a set of aluminum alloy parallel groove clamps (connecting OPGW optical cable and grounding wire) and a terminal (connecting to the iron tower). Usually, one terminal tower and linear tower are equipped, and two connecting towers are equipped.

Suspension string fittings include U-shaped screws, suspension clamps, pre-twisted wire protection lines, grounding drain wires and necessary connection fittings. The mechanical strength of the hanging string connection fittings is 70kN. The suspension clamp is a pre-twisted wire type, and the clamp body is made of aluminum alloy. The clamp body should be equipped with an EPDM rubber cushioning elastic pad. The allowable value of the drape angle at the outlet of the OPGW single drape clamp is not less than 15 degrees.

The wire clamp is composed of a rubber clamp block, a pre-twisted wire and a cast aluminum casing. 1. Enhance the rigidity of the cable hanging point and increase the radius of curvature. The single-line clamp can meet the 30° steering angle, and the double-line clamp can meet the 60° steering angle. 2. It can be ensured that the cable is not subject to large bending stress near the outlet of the wire clamp, so as to avoid local mechanical damage causing strand break or wire breakage.

Power equipment optical cable communication 4D type protective hardware anti-vibration hammer with armor rod. Features: Due to the use of hammers with different sizes and masses, the response frequency range of traditional shock-proof hammers is expanded. Because the shapes of large and small hammers and hooks have no edges and corners, corona is reduced. In addition, the use of aluminum alloy for the hook can also reduce the energy loss of the wire.
