Two-in-one HV cable guide and clamp is a world first

12 January 2015

Cable cleat manufacturer, Ellis has launched the world’s first two-in-one cable guide and clamp for the installation and subsequent restraint of high voltage (HV) cables.

Initially designed for an offshore project for Siemens, the Cable Guide Clamp has now been developed by Ellis into a full range suitable for use with large diameter cables.

The challenge set by Siemens for the Ellis team - which had previously developed a roller-system for the installation of HV cables in power tunnels - was to develop a system that would feed, and then restrain, seven 117mm diameter cables along a specified route within a fabricated structure, which featured a significant number of twists and turns.

The Cable Guide Clamp achieves this in two stages. Firstly, cables are guided by it into their final location, while trumpeted entry and exit points ensure the cable is not damaged when fed through particularly sharp angled turns.

Once the cable is laid correctly, the top half of the guide is removed, a fixing piece installed directly onto the cable and the top half re-secured, thus turning it into a fully-functioning HV cable clamp.
