Arthur Flury - Material for Overhead Contact Lines

Arthur Flury, founded in 1920, is a leading worldwide specialist for the design and manufacture of components for overhead contact lines.

Our product line contains conical couplers and forked collar sockets for easy and quick installation, all kinds of dropper variations, contact wire splices, any kind of special clamps, and a large range of temporary and permanent earthing material.

High-quality section insulators, phase breaks and composite insulator rods

The well-designed section insulators, used for all common voltages, phase breaks and lightweight composite insulator rods, are the major components in our product range. Various systems around the world have been equipped with these high-quality parts for over 30 years.

A clever product concept, mostly of copper-based alloys or high-grade stainless steel and manufactured by cold-forming processes, ensure light, strong and reliable components for a long service life.

Complete range of fixing components

A complete range of fixing components can be provided with our conical couplers, forked collar sockets, droppers suitable for any railway system, contact wire splices and special clamps.

A comprehensive overhead contact line earthing program

Arthur Flury has a comprehensive program for the temporary earthing of overhead contact lines during maintenance and repair.

The fundamental or deep earthing system for such structures as masts, antennas, chimneys, towers, transformer stations and houses meets the requirements of electrical engineering and lightning protection technologies. The systems are highly reliable, with lightweight voltage testers, up to 36kV, as supplementary products.

Section insulators for ac/dc and phase breaks for ac systems

These insulators and phase breaks are developed and manufactured according to our extensive activity in numerous international projects. Our worldwide exposure ensures sensitivity to this issue and the transfer of our experience gained on various rail operations.

We provide sectioning devices for DC trolley systems, DC tramways, and suburban, freight and high-speed railways (up to 200km/h, from low voltage up to 25kVAC).

For connecting different phases or high-voltage systems in the overhead line, we are specialists in developing custom-made voltage separation as well as automatic switched phase breaks. The composite insulator rods for contact wire and catenary wires are a very important part of this technology.

Specific overhead line solutions

Through years of research we have developed products and accessories of lightweight construction for this age of high-speed railways. Thanks to our comprehensive know-how and modular batch production, optimal solutions for every railway company can be offered.
