Trefoil Clamps

Trefoil Clamps are used for high voltage  single  core cables  where  the  current rating is high and 3 core cables are not available. The Trefoil 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’s nullify  the  induced magnetic field of high voltage power cable. The Trefoil Clamps  are Protection  of  power  and  control  cable  from  the lightning discharges and Establishment of easy cable circulation paths. Applications:-

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