The working principle of suspension clamp for OPGW cable​ is to achieve reliable fixation and flexible protection of optical cables in a dynamic force environment. In fact, the workflow of a set of high-quality suspension clamp for OPGW cable in actual working conditions needs to be supported by a variety of technical designs.

The main role of downlead clamp​ is to achieve a precise and stable connection between the overhead wires and the terminal equipment. In the terminal link of the transmission line, the wire needs to be transferred from the overhead state to the ground equipment connection. In this conversion process, the downlead clamp needs to continuously withstand the gravity and wind loads of the wire, as well as the stress changes caused by the thermal expansion and contraction of the wire due to changes in ambient temperature.

The biggest advantage of using preformed armour rods for ACSR conductor is that it builds a comprehensive and long-lasting safety protection for transmission wires, eliminating the risk of outages caused by wire damage from the source.

Cable joint box is a sealed box device used to connect two or more optical cables in a optical cable line, protect the optical fiber fusion joints, and provide mechanical strength support.

​If you want to effectively maintain the suspension clamp for OPGW cable, you must first understand the working environment and failure risks of the fixture. Suspension clamp for OPGW cable is exposed to the outdoors for a long time, not only withstanding the dynamic stresses of OPGW cable's own weight, wind, ice and snow loads, but also facing the erosion of complex environments such as ultraviolet rays, acid rain, and salt spray. Under the superposition of these factors, the metal parts of the fixture may rust, fatigue and fracture, and the rubber liner is easy to age and lose elasticity, resulting in loosening or even falling off of the OPGW optical cable. Therefore, regular inspections are the basic part of maintenance work.

The preformed downlead clamp​ is a connecting component that allows current to be conducted efficiently and safely. It is mainly used to fix and support the ground conductors in the lightning protection lead-off line or power system, so that the conductors can maintain a stable position during long-term operation and avoid loosening or breaking of the connection due to external forces, environmental corrosion and other factors, so as to ensure the safe operation of the entire power system or lightning protection system.
