Ellis Patents | Cable Hangers & Cleats Supplied in the UK by Thorne & Derrick
Pegasus is a modular cable hanger system that is stronger, lighter and, because it is has been designed to be made to order, incredibly flexible in comparison to traditional J-type galvanised steel cable hanger systems.
Pegasus from Ellis Patents comprises a non-corrosive marine grade, extruded aluminium spine that supports any number and combination of plastic cable hangers that are manufactured from a high strength nylon especially formulated to meet the requirements of the London Underground 1-085 specification.
Pegasus Benefits for Hanging CablesÂ
– Corrosion free nature as a result of there being no bimetallic contact and the aluminium spine being fully enclosed to protect the hanger system against the corrosive effects of brake dust.
– Curved saddle shape on all cable hangers that prevents cable damage caused by sharp edge contact with the outer sheath or jacket of the supported cables.
– Modular design that allows assembly with any number of hangers in any combination, giving designers the ability to produce the cable layout they want.
Manufactured by Ellis Patents, the global market-leader in the manufacture of cable cleats for the management and support of LV MV HV cables.
February Rail Project | Working with Ellis Patents we completed the specification and have now moved into manufacturing for our largest contract to date to supply TfL (London Underground) approved cable hangers across several depot modernisation projects.
Thorne & Derrick in consultation with the Asset Manager at Transport for London and their appointed Telecoms & Power contractor secured formal Authorisation & Approval for the Pegasus range of non-metallic cable support hangers.
The product will provide safe cable management of the cable route within the Bridges & Structures category – over 1000 hangers with proven lifecycle performance and utilising the standard J-type design for support of multiple cable runs including single, 3-way and 5-way configurations are now scheduled for delivery.

Working with Orsted, Van Oord and the Inter Array Project Manager from LS Cable & System, Thorne & Derrick have specified a cable sealing system to prevent water ingress into the power and fibre optic cores of de-energised high voltage inter-array cables (IAC).
Manufactured by 3M Electrical their range of EC type Cold Shrink cable end caps will provide protection from exposure to moisture, contamination, corrosion, ozone, UV radiation and other environmental hazards.
The proposed product solution was adopted based upon safe working procedure, field service history and product testing according to ASTM D 412-75: – the Cold Shrink technology cable caps are a flame-free and tool-less installation.
The 3M EC-4 type cap will be applied to protect and seal the exposed power core cable ends following the cable pull-in in general accordance with the installation process outlined in the video below – these will be mounted by the Cable Installation Contractor on the wind turbine foundation and offshore substation (OSS) after removal of excess pull-in lengths.
The fibre-optic cables will be sealed with 3M EC-1 type cap – Scotch 2228 type mastic tape is used to wrap and build-up the diameter of the fibre optic cable where the outer diameter of the FO cables are smaller than 11.6mm. Scotch 2228 is a conformable, self-fusing electrical rubber mastic tape with a strong, temperature stable adhesion for maximum continuous operation up to 90° Celsius.
The Changhua 1 and 2a offshore wind farms will comprise a total of 111 Siemens Gamesa 8 MW turbines. The offshore construction will be carried out during 2021 and 2022, with the project expected to be fully up and running in 2022.
Thorne & Derrick have established an impressive project portfolio across UK, European and US built data centres; supporting the ever-changing industry and modern infrastructure changes with LV-HV Energisation & Electrical Equipment.
This month we supplied cable cleats and management products NTT’s Hemel Hempstead 2 (HH2) Global Data Centre. The HH2 facility provides 6MW of high quality data centre space across 6 data halls – each data hall has its own dedicated plant to a 2N configuration. With 30,000 square feet of net technical capacity, Hemel Hampstead 2 offers excellent connectivity options providing access to multiple carriers and cloud providers. 20kW is possible with high-power rack densities.

Working with Ellis Patents, Thorne & Derrick specified and supplied the following cleats for high voltage cable restraint to the client:
Cable Cleats For Short Circuit Protection
A cable cleat is a device designed to provide securing of cables when installed at intervals along the length of the cables, and is a vital component to ensuring worker safety. Holding Power is Ellis Patents guarantee that their Cable Cleats will contain dangerous short circuit forces – protecting your people, power and plant. It is important that when selecting cable cleats for high voltage cables that the cable cleats can handle the anticipated fault currents especially at working voltages of 11kV/33kV.Â
All cable cleats stocked and supplied by Thorne & Derrick are short-circuit tested to the current updated version IEC61914:2015. Read the blog for further information on conforming to the current IEC standard âž¡Â Withdrawn IEC 61914:2009 | Cable Cleats for Electrical Installations
