Cable Trefoil Clamps & Cleats
Cable Trefoil Clamps & Cleats
Electromac Industries, an ISO certified company, is in the business of manufacturing high quality Cable Trefoil Clamps and Cleats conforming to most demanding standards to various industries since 1972. Trefoil clamps are used for high voltage single core cables where the current rating is high and 3-core cables are not available. 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 nullifies the induced magnetic field of high voltage power cable. Trefoil clamps are used for protection of power and control cables from the lightning discharges and establishment of easy cable circulation paths. Materials of construction: halogen free fireproof; FRP glass fibre filled; Nylon/Nylon 6; cast aluminium (LM-6); aluminium strip; CA single and double claw type; and PVC/HDPP/PP. These are type tested for short circuit at M/s ERDA, Vadodara, for RMS value: 40 kA, for 1 second peak value: 100 kA). The company also manufactures PG EMC cable glands (WP and FLP); and FRP junction boxes and trays
Trefoil clamps are suitable for supporting single core PVC/HRPVC, XLPE, XLPE insulated aluminium, un-armoured, earthed and unearthed power cables from 1.1 kV to 132 kV grade, 3-phase AC circuits in trefoil formation in generation stations, 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.
