CABLE CLEATS PICTORIAL INDEX
FAULT RATED CLEATS
Cable Cleats/Trefoil & Single Cleat are designed to support and retain cables within a cable tray system in various conditions. The main function is to secure cables and prevent damage in short circuit conditions, Cable Cleats need to be tested under these conditions. Unistrut® now have a range available that are tested to world standards. Unistrut® Cable Cleats are tested and comply to IEC 61914 – the TC and SC range of Trefoil cleats for 13mm to 128mm and single cleats 13mm to 150mm in market demanded design.
NON FAULT RATED CLEATS
Unistrut® also have a range of Non Faulted Rated Cleats. These are used to bundle low voltage cables and conduits.
INSTALLATION NOTES
The cleats should be installed properly to secure the cables. Every cleat should be restrained to the tray, the bend radius should be 8-12 times the cable diameter. The cleats should always be installed at the beginning, middle and end of the bend. The distance of the cleats at the bend should be no more than 300mm.
