Trefoil Cable Clamps is essential for Single core cable


Trefoil Cable Clamps are used for high voltage single core cables where the current rating is high and 3 core cables are not available. Trefoil Cable Clamps are used for laying single core cables in Trefoil touching formation which helps to maintain magnetic symmetry thereby avoiding electro magnetic heating and loss of current. It does nullify the induced magnetic field of high voltage power cable.


The Trefoil Cable Clamps are  Protection  of  power  and  control  cable  from  the  lightning   discharges  and Establishment of easy cable circulation paths.


Voltages are induced in the sheath of cables running in parallel which result in circulating currents flowing in the 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 minimized and hence the circulating currents. The circulating currents cause localized heating.



Trefoil Cable Clamps are  suitable  for  supporting  Single  Core  PVC/ HRPVC, XLPE, XLPE Insulated Aluminum, Un- Armoured, Earth And Un Earth Power  Cables  from  1.1  Kv  to  132 KV Grade.  3 Phase A.C. Circuits in trefoil formation in Generation Stations, Sub-Stations, Thermal Power Stations, Switchgear Plants etc. These can be used for indoor or outdoor for vertical or horizontal running cables inside trenches or on racks.
