Main Page Railway infrastructure Overhead line equipment
In addition to devices for tensioning traction or suspension systems, it also offers small components for traction accessories. They include, among others, various types of clamps used to fix and join together wires on the overhead line. Booms that support the suspension cable also fall into this category. Despite their small size, these elements are necessary for the proper operation of the railway overhead line.
It is used for the group earthing system. It is attached to the top of the structure. Enables the AFL6-120 type cable to be suspended above the overhead line. The boom is a compact structure, the main shank being a dia 60 mm steel tube welded to a base that is fastened to the pole. The entire structure is galvanized and then powder coated.
The purpose of our product is to connect the contact wires and the support line to the tensioning device. It is designed in such a way that it simultaneously tensions the wires and the catenary with an appropriate distribution of the tensioning forces. The distribution of forces depends on the ratio of lever arm lengths. The ratio of arm lengths depends on the tensions required and therefore on the design of the overhead line. The innovation lies in changing the thickness of the material and changing the manufacturing technology. The stiffening element of the lever is bent, while in the old solution it is welded.
The product is used when overhead line consists of two contact wires, in which case it is necessary to align their tensions at anchoring. It is a double-arm lever to the ends of which the contact wires are attached. The wires are fixed in the crimping sleeves according to the self-crimping principle. The innovation of this device is the elimination of end handles. The new equalizer combines the crimping of contact wires and the compensation of wire length differences into a single device.
