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
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 Vulcan+ Quad 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 installation.
Ellis Patents Vulcan+ Quad Cable Cleats are stainless steel quadrafoil cable cleats for cable diameters ranging from 23-70mm for cable applications where the highest 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.
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.
