Thorne & Derrick International, based in the UK, stock and distribute the complete range of cable cleats and cable hangers manufactured by Ellis Patents including Emperor cleats for short circuit retention and cable protection of LV (Low Voltage), MV (Medium Voltage) and HV (High Voltage) cable systems in single-way or trefoil installation.

Ellis Patents Emperor Cable Cleats are stainless steel trefoil cable cleats for cable diameters ranging from 19-128mm for cable applications where the highest level of short circuit withstand are required.

Emperor cable cleats are designed for rapid installation and offer the ultimate protection against the harshest environmental conditions.

The frame is tightened and locked using a combination of M12 set screw, nyloc nut and washer in A4 stainless steel, screw head retainer in LSF Nylon (Zero-Halogen, Low Smoke & Fume) and LSF polymeric washer. The cleats are also supplied with an integral LDF polymeric liner and base pads.

International Standard IEC 61914:2009

Ellis Patent cable cleats manufactured from stainless steel with international specifications are used to clamp and retain LV MV HV cables including 11kV and 33kV networks depending on short-circuit calculations according to IEC61914 calculations.

For cable installations where corrosion protection is required, including onshore and offshore substations or hazardous area locations, see our complete range of  ➡ stainless steel cable cleats.

Project Application: Emperor Cleats (Oil, Gas & Petrochemicals) – cable cleat manufacturer, Ellis Patents recently demonstrated export expertise and excellent in providing high specification trefoil cable cleats compliant with ADCO (Abu Dhabi Company for Petroleum Oil Operations) requirements for the cable management of medium/high voltage (MV-HV) on the Al Dabbiya Surface Facilities project. Emperor cleats designed to clamp and support cables where the highest levels of short circuit protection are required are available for both single and trefoil applications – manufactured from 316L the stainless steel cable cleats provide excellent corrosion protection for cable management in both onshore and offshore hazardous area locations.

Installing Cable Cleats

Installation instructions for single way cables using Emperor cleats manufactured by Ellis Patents:

Remove the closing flange nutRemove the base padReplace the appropriate padClosed the hinged arm
1. Remove the closing flange nut.2. Remove the base pad (if required) and fix the cleat to support structure using either the single central or two outer fixing positions.3. Replace the appropriate pad and install the cables.4. Close the hinged arm and refit the flange nut (18mm socket required). The head of the screw is held in position so that only a single power tool is required to tighten the nut from one side.

Important. Do not over tighten the cleat. The liner should be in contact with the cable but does not need to be so tight that the cable bulges at either side of the liner.
