Prysmian Trefoil Cleats
Prysmian - formerly Pirelli Cables, formerly BICC (BICON) - 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 aluminium trefoil cleats are recommended for retaining three single core cables in trefoil formation.
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 bends.
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.
T&D distribute the complete range of Prysmian (BICON) cable cleats including mulicleat, trefoil, claw, hook, single and two bolt cleats manufactured from plastic nylon (LSF), stainless steel and aluminium for LV-HV cable support and containment in short-circuit conditions.
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.
