There are many types of preformed tension clamps, which can be divided into preformed conductor tension clamps, preformed ground wire strain clamps, preformado guy end grip, etc.

In modern power transmission and transformation systems, preformed conductor tension clamp has become the preferred solution for connecting conductors. Compared with traditional bolt-type and compression-type tension clamps, preformed conductor tension clamps have obvious advantages in mechanical performance and reliability. From the perspective of material selection, preformed conductor tension clamps are mostly made of high-strength materials such as galvanized steel wire or aluminum-clad steel. The special preformed structure design not only provides reliable grip, but also effectively protects the conductor from damage. So, what points should be paid attention to during the actual installation process? This article will explain in detail the correct installation method of preformed tension clamps.

Helical-formed suspension clamp is used to connect various conductors such as ADSS optical cable and OPGW optical cable on straight pole towers, and is used for the suspension conductors and ground wires of pole towers. Helical-formed suspension clamp can effectively protect the conductors, assist in vibration reduction, and can well extend the service life of the wire line. So do you know what other characteristics and advantages it has?

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?
