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

Ellis Patents Colossus Cable Cleats are stainless steel trefoil cable cleats for cable diameters ranging from 24-170mm for cable applications where the highest level of short circuit withstand and protection is required. The cable cleats have the uniquely designed LSF polymer frame.

Colossus cable cleats are able to withstand moderate levels of short-circuit and are available in a range of sizes that are suitable for trefoil cables up to 170mm in diameter.

The Colossus cleats are able to provide a more suited support solution for larger cable sizes and the polymer frame provides further protection to the cables during short circuit conditions.

It is recommended that the cable cleats use either 10mm or 12mm bolts that can be bought separately.

International Standard IEC 61914:2009

Ellis Patent cable cleats 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.

INSTALLING CABLE CLEATS

Installation instructions for trefoil cables using Colossus cleats manufactured by Ellis Patents:


1.Remove the closing flange nuts and set screws.	2. Fix the bottom half of the cleat to the support structure using M10 or M12 fixings as appropriate.	3. Lay the LV MV HV cables in place.	4. Fit the top half of the cleat over the cables. Secure with the M12 setscrews and flange nuts (19mm spanner/socket for setscrews, 16mm spanner/socket for flange nuts).	5. 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 cleat liner.
