Formerly Pirelli Cables, formerly BICC (BICON)

376AC Series Cable Cleats

Prysmian trefoil cable cleats suit 24-76mm cable diameters and are specified for installing three single core cables in trefoil formation. Prysmian trefoil cable cleats are available with single or two bolt fixing.

Prysmian BICON trefoil cleats can be used at a maximum fault current level of 30kA RMS if spaced at 900mm on straight cable runs and 300mm on vertical bends and horizontal bends on each support with, if necessary, intermediate unanchored cable cleats to limit resistance spacing to 300mm.

Trefoil cable formation is installed where three phases are carried by three single core power cables rather than a single multicore cable.

Installing three single core cables using trefoil cleats minimises the induction of eddy currents and maintains current carrying capacity of the circuit.

Trefoil Cable Cleat Applications & Fault Ratings

Prysmian BICON trefoil cable cleats are installed to provide cable clamp and support restraint to single core cables laid in trefoil formation, especially single core XLPE AWA aluminium wire armoured cables to BS5467 and BS6724.

Single Core Cables Installed in Trefoil Formation

Voltages are induced in the sheath of power cables running in parallel which result in circulating currents flowing in the cable sheaths.

The distances between single core cables running in parallel determine the voltages induced. With single core cables in trefoil formation (touching each other) the distances between the cables are minimum and thus the voltages induced are minimised and hence the circulating currents - the circulating currents cause localised heating.

Prysmian Aluminium Trefoil Cable Cleats, Single & Two Bolt
