Helwin Beta 690MW grid link
The requirement was to feed seven 117mm diameter cables along a specified route within a fabricated structure, which featured a significant number of twists and turns. The problem was that there was no existing product that would enable the cables to be installed in an efficient, safe and cost-effective manner.
Bespoke Cable Guide Clamp
The Ellis Patents team, which had previously developed a roller-system for installation of HV cables in power tunnels, took stock of the situation and set to work developing a solution that would secure the Siemens specification, and see them become the first company in the world to offer a two-in-one cable guide and clamp.
Within six weeks of the initial meeting, Siemens had approved our new product design, two weeks later five working prototypes successfully passed an installation trial in Germany and less than a month after that Ellis received the order and had the tooling ready for mass production.

Severn Tunnel Electrification
Network Rail
Ellis Patents were involved in the Network Rail project to electrify the Severn Tunnel. The requirement was for a solution to carry the insulated ATF cable. An added complication for Ellis Patents was the aggressive conditions within the tunnel and the requirement for a 40 year product design life.
Cable Clamp
Ellis Patents Solution
Ellis worked with Network Rail to develop a solution based around the proven 2F+ two hole cable clamp alongside a bespoke bracket manufactured from Super Duplex stainless steel.

New Wear Bridge Crossing
Northern Power Grid installed power cables under the New Wear Bridge as a new main supply route. The existing route on the Queen Alexander Bridge was scheduled to be decommissioned due to its age and the phasing out of oil filled cables. The cable installation is unique in that it requires the cables to be suspended under the bridge and above a river. The cables are carried in Emtelle ducts.
Balfour Beatty were contracted by NPG to install the cables, they in turn approached Ellis to provide a cable duct support solution.
Cable Duct Support System
Ellis Patents Solution
Ellis worked with Balfour Beatty to develop a product to suspend the duct from the underside of the bridge, and also develop an installation methodology. The solution was based around on 12 off standard 2F+ clamp with a bespoke stainless steel structure.
240 assemblies in total were supplied. The frames hang from the underside of the bridge and support ducts supplied by Emtelle. Power cables are then installed into these ducts.

Our first specification for Areva was for its OL3 reactor in Finland in 2009, and was secured as a result of our proven technical expertise and excellent industrial references.
Emperor & ProTect Cable Cleats
Ellis Patents Solution
Emperor Cable Cleat
The Emperor Cable Cleat is designed for use where the highest levels of short circuit withstand are required, Ellis’ Emperor cable cleats are available for both trefoil and single cable applications. All products in the range are manufactured in type 316L stainless steel, meaning they provide ultimate corrosion protection, even in the harshest of environments.
The benefits of the Emperor cleats also extend to a patented design, which makes installation quick and easy, and an integral LSF zero halogen polymeric liner and base pad that protects and cushions cables during short circuit.
ProTect Cable Strap
Ellis’ ProTect cable straps, which are manufactured out of 316L stainless steel, are designed for installation between trefoil cleats, such as Emperors. They not only enhance short circuit capabilities, but help to retain trefoil formation and, because they allow for greater fixing distances between cleats, can reduce installation time and cost.
