Convex Cable Hangers | Supporting Rail Cables & Tunnel Wall Applications

Published 08 Mar 2021

Convex Cable Hangers

Thorne & Derrick distribute a range of Cable Hangers, including convex cable hangers from Ellis, for low, medium and high voltage electrical systems; typically distributing LV 6.6kV-11kV-33kV electrical power.

Our cable hangers and accessories range include:

• Cable Hangers – Galvanised Steel Cable Hanging Systems (LV MV HV Cable)
• Cable Hangers – Non Metallic Cable Hanging Systems (LV MV HV Cable)
• Cable Hooks – LV MV HV Cable Suspension Hooks

Cable hangers support single or multiple cables – hangers are available in both galvanised steel and nylon and are used to support horizontal cable routes to building and tunnel structures. A complete range of steel cable hooks are also available compliant with 18th Edition of the IET Wiring Regulations (BS7671) is effective as of January 1, 2019.

CABLE hangers IN THE RAIL INDUSTRY

Convex Cable Hangers | Supporting Rail Cables & Tunnel Wall Applications

Investment in the rail sector has grown rapidly over the last decade and much greater funding is expected going forward. Both UK and worldwide, there is a growing ambition for more modern, reliable and sustainable mass transit systems.

Ellis has the most extensive range of cable cleat designs and accessories on the market which are suitable for all applications within the rail industry. Overground and underground rail sectors use an extensive range of cable types including telecoms, alarm and control cables, signalling and data, and a range of power delivery and electrification cables. Many rail cables are installed using cable hangers. Ellis has improved the design of the basic galvanised steel hanger with reduced weight, radiused corners (to reduce damage to cables during installation) and a convex hanger profile for cable sagging.

Cable hangers are curved to fit the profile of a tunnel to assist with tunnel wall applications.

These reduce the level of supporting steel structures necessary as the hangers can attach directly to the tunnel profile. Where the kinematic envelope of trains is tight and space is restricted, these profiled hangers provide an effective solution.

Ellis has now enhanced a cable hanger product that has been one of its best-sellers for over 20-years. The technical team have taken the company’s cable hangers, which are used primarily in the rail industry and made them stronger and, remarkably cheaper.

Stephen Walton, Ellis’ Technical Director, said: “We’ve been successfully manufacturing and selling our cable hangers for two decades, and it’s fair to say that the design is tried, tested and completely trusted by all those who use it.”

Ellis achieved this by looking at every aspect of the product and looking at ways to improve on it. The first key development is that there are two different versions of the new Ellis cable hanger – a standard Mk2 cable hanger, and a convex hanger; the latter designed specifically for use in tunnels, where the mounting surface is often curved.

Benefits of the new Mk2 cable hangers include:

• Rounded corners that reduce snagging points
• Spin galvanized (55µm or 150µm thickness) to protect against erosion
• Only 6mm thick, leading to reduced product and shipping costs
• Wide range of sizes available
• Suitable for cables up to 100mm diameter
• Custom designs available
• Rolled designs for tunnels available

Meanwhile, the convex cable hanger has all the benefits of Mk2, plus:

• The removal of all sharp edges presented to the cable by traditional hangers
• Through innovative design, it’s the same strength as Mk2, but only 5mm thick

Technical Information

Material: Galvanised Mild Steel

Application: Hang cables on walls and support structures

The NEW convex cable hanger are manufactured in Galvanised Mild Steel and have a curved back plate to suit tunnel wall applications. The convex profile of this hanger reduces the risk of cable damage and facilitates cable sag. The main use of these hangers is to hang cables on walls and support structures in the rail industry.
