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.

Spiral vibration damper is a professional device used on overhead transmission lines to suppress the breeze vibration of wires. Under the action of a stable breeze, the wires of overhead transmission lines will produce periodic vibration perpendicular to the direction of the line, which is what we call breeze vibration. This seemingly slight vibration, if it persists for a long time, will cause metal fatigue of the wire, which will cause serious problems such as broken strands and disconnections, and pose a great threat to the safety and stability of power transmission. Through its unique structural design and physical principles, spiral vibration damper can effectively consume vibration energy and control the vibration amplitude of the wire within a safe range, thereby extending the service life of the wire and ensuring the reliable operation of the power system.

The two main reasons for grounding are to protect the safety of personnel and equipment and to ensure the stable operation of the electrical system. According to statistics from the International Electrical Safety Association, in industrial environments where there is no perfect grounding system, the incidence of electric shock accidents is more than 5 times that of standardized grounding scenarios. The grounding system can quickly introduce leakage current into the ground, reducing the potential of the equipment housing to a safe range.
