Cable Cleats & Trefoils

General Information

ASEplas Cleats are able to support medium and high voltage power transmission cables. Typically from 33kV to 500kV. The ASEplas Cleats can be supplied with DTS cable slots.

ASEplas Cleats are Non metallic so therefore have no problems with dissimilar metals when fixing to supporting structure or heat build up from magnetic field. They are a cost effective alternative to aluminium, does not require epoxy or other protective coatings.
ASEplas Cleats are Robust and durable with a Design life of 40 years minimum.
Strength checked using finite element method calculations supported by extensive laboratory testing.
Resilient liner prevents cable damage due to movement and expansion; also allows for tolerance in cable diameters.
Atlantic Supports Engineering Cable Cleats are used on:

  •   Tunnels, bridges and masts

  •   Flexible (sag) and rigid cable systems

  •   Vertical shafts, sharps bends and cable joint bays

  •   Trefoil and single cable systems

  •   Cables with fibre optic sensors

Photographs

ASEplas cleats were designed as a high strength durable product, capable of being used in the most arduous conditions. Here are a variety of drawings and photographs showing their application.

Finite Element Analysis

The "safe working loads" shown in the specifications are applicable in all directions. These "SWL's" have been shown by subsequent more sophisticated analysis and laboratory testing to be very conservative.

All Atlantic Supports Engineering's Cable Cleats have been subjected to rigorous design analysis and laboratory testing to ensure that they are fit for their purpose of supporting cables safely for a long period of time in a variety of conditions. Design analysis uses the Finite Element Method for stress and displacement calculations. We are fortunate in having links with the Civil Engineering Department at the nearby University of Wales, Swansea which is one of the premier FEM research units in the world.
