The wires in old residential areas and alleys are messy, like "spider webs" entangled in corridors or exterior walls, which not only affects the appearance, but also poses safety hazards. Recently, a "beautification surgery" for the "spider webs in the air" in old residential areas was launched in Yuhai Town. Through departmental linkage and residents' co-governance, the messy flying wire charging and hanging cables in the past were sorted out one by one, achieving a double improvement in "appearance" and "safety value".

In transmission lines, preformed tie wire is becoming the choice of more and more power grid companies. According to industry data, the domestic purchase volume of preformed tie wire in 2023 increased by 35% year-on-year, and some wind power projects even listed preformed tie wire as the standard for cable protection.

Although the production cost of Preformed fittings is slightly higher than that of traditional power fittings, in the long run, the use of Preformed fittings can greatly reduce the operating cost of the line. Do you know what Preformed fittings are? What are their functions?

Protective fittings are a type of fittings used for line protection in power fittings. They are key components used for protection in power lines, such as preformed vibration damper,Preformed tie wire and cable fitting pole clamp, which ensure the electrical and mechanical safety of lines in different scenarios. Do you know their specific applications?

In a 500kV high-voltage transmission line project in the southwest region, ADSS optical cables need to cross a deep canyon of nearly 800 meters. The wind here is strong all year round and it is easy to freeze in winter, which poses a challenge to the suspension of optical cables. In response to this phenomenon, the transmission project adopted ADSS suspension clamps to solve it.

Preformed Helical Suspension Clamp is a common hardware for hanging optical cables on transmission line towers, and it plays an important role all the time. Preformed Helical Suspension Clamp is mainly used for connecting optical cables with straight towers or towers with an angle of less than 25°, one set for each tower. The wire clamp can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, and overcome the dynamic stress of wind vibration; it can also ensure that the bending of the optical cable does not exceed the allowed value, so as not to generate bending stress, thus ensuring that the optical fiber will not be lost.
