Preformed Tie Wire is a cable assembly prefabricated in a specific spiral shape by multiple strands of metal wire or composite materials. It is used for overhead power conductors and power overhead optical cable terminals, suspensions, joints, etc. It does not need to be twisted on site and can be directly installed. At present, Preformed Tie Wire is often used in power transmission and distribution, optical fiber communications, electrified railways, cable TV, construction, agriculture and other fields.

In the daily maintenance of power lines, Preformed Tie has become the choice of many power supply units. "It used to take two people to wind the protective wire, but now one person can do it easily." This is the biggest feature of Preformed Tie. Compared with the tedious operation of traditional protective wires that require on-site winding, Preformed Tie adopts a factory prefabricated molding design, and only needs a simple sleeve to complete the installation.

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?
