Quad Cleats

Quadrafoil is a cable installation method for single-core cables where the neutral is bundled with the 3 phase conductors – no advice is referenced in BS7671 but a report producted by ERA for Ellis Patents delivered the following guidelines:

  • Current ratings given in BS7671 for cables in touching trefoil cleat formation are appropriate for cables in quad bundles
  • Derating factors given in BS7671 for cables in touching trefoil cleat formation are appropriate for cables in quad bundles
  • Voltage drops for circuits in quad formation should be calculated using the values tabulated in BS7671 for cables in flat touching formation
  • When considering multiple cables per phase, the advice given in Guidance Note No.6 for trefoil groups is applicable to quad bundles
  • The induced voltage in the neutral conductor of a quad group is minimal and can be ignored

Ellis Patents Vulcan Quad Cable Cleats are stainless steel quadrafoil cable cleats for cable diameters ranging from 23-70mm for cable applications where the level of short circuit to withstand is moderate.

Vulcan Quad cable cleats are compact in design for easy installation when space is limited and offer the ultimate protection against the harshest environmental conditions.

The cable cleat comes with an integral Low Smoke and Fume Zero Halogen Polymeric liner and base pad offering the cables protection during short-circuit conditions.
