Purpose of use of Aluminium Trefoil Clamps :

• Aluminium 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 Aluminium Trefoil 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.

Application :

• Aluminium Trefoil 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, 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.
