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.

The product is mainly used for fixing and anchoring overhead self-supporting ADSS optical cable lines, and is generally installed in terminal towers, tension towers, corner towers, etc. Each set of tension clamp components includes: inner twisted wire, outer grade wire, and pull ring. Customers can configure and purchase other connectors according to design requirements. The special design of the preformed wire ensures the grip of the product while better protecting the optical fiber of the optical cable from being squeezed and damaged, and the optical fiber signal transmission will not be attenuated. Tension clamp has the advantages of uniform stress distribution, no stress concentration point, good dynamic stress tolerance and good anticorrosive performance.

Suspension clamp for OPGW cable is a connecting fixture that suspends the OPGW optical cable on the transmission line pole tower. Suspension clamp for OPGW cable can reduce the static stress of the optical cable at the suspension point, improve the vibration resistance of the optical cable, suppress the dynamic stress of wind vibration, and ensure that the bending of the optical cable does not exceed the allowable value, so that the optical cable does not produce bending stress, so the optical fiber in the optical cable will not produce additional losses. Suspension clamp for OPGW cable is mainly used for hanging optical cables on overhead OPGW composite ground cable lines, which has a similar effect to ordinary overhanging wire clamps. It is suitable for OPGW optical cables, wires on transmission lines, and ground wires.

In the field of electric power, high-performance metal fittings are an important tool for the safe and stable operation of the power grid. Vilun Electric Co., Ltd., as a national-level high-tech enterprise, it has been focusing on the research and development and manufacturing of spiral power fittings and laser equipment for many years, providing safe and reliable solutions to the global power industry. The company has always implemented the concept of “technology for development, quality for survival”, and used its best efforts to help customers improve work efficiency and reduce maintenance and operation costs and risks.

Suspension clamp is a device used to support and fix conductors (wires) on overhead power lines. The purpose of Suspension clamp is to hold the conductor in place while allowing movement caused by thermal expansion, wind, or other environmental factors.In layman's terms, the reason why the wires on the poles that we can see on the street every day can be hung steadily is that there are optional Suspension clamps to fix them so that the wires will not be easily stretched or blown by the wind. Swing at will. Suspension clamp is usually installed on a pole or tower and is a key part of the suspension assembly, which includes various components such as the clamp body, bolts, and brackets.
