Helical Dead-end for OPGW provides reliable tension support for optical ground wire routes. It anchors OPGW cable at strain towers, corner towers, and terminal towers. Therefore, it plays an important role in aerial fiber and power transmission networks.
This product belongs to ADSS & OPGW Hardware systems. It also supports projects that use both ADSS cable fittings and OPGW line hardware. For this reason, contractors can manage overhead fiber hardware through one coordinated product group.
The dead-end set uses preformed helical rods. These rods wrap around the OPGW cable and create a stable gripping area. As a result, the clamp helps spread axial load along the cable surface. This design reduces concentrated stress near the cable core and optical fibers.
A complete set can include outer-layer dead-end rods, inner-layer reinforcing rods, a thimble, a shackle, a link plate, and grounding fittings. The final configuration depends on cable diameter, rated tensile strength, tower type, and project drawings.
The rod material can use aluminum-clad steel wire or galvanized steel wire. Both options provide mechanical strength and outdoor corrosion resistance. In addition, the formed-wire structure supports quick field installation. Crews can install the rods by hand and check the finished position visually.
This OPGW dead-end clamp suits transmission lines, utility fiber routes, and power communication networks. It helps maintain cable tension, improves connection stability, and supports long-term line reliability.
For a complete overhead fiber installation, this product can work with suspension clamps, vibration dampers, downlead clamps, splice closures, and cable storage brackets. Together, these products form a full ADSS Hardware and OPGW hardware solution for pole and tower applications.

Double Helical Dead-end for OPGW
Usage and Characteristics
When OPGW optical cables are applied to specially designed power lines with long spans, high elevation differences, and large line angles, double strain clamps can be used. The helical double strain clamp features a three-layer design consisting of inner, intermediate, and outer helical armor rods. This structure greatly improves tensile strength and imposes no limitations due to line angles. The complete clamp assembly includes: helical armor rods, grounding wires, and matching connectors, among others.
