Trefoil Clamp - Polyamide/Nylon/FRP (Non Magnetic Body & Hardware) suitable for 11kV, 1CX630sqmm Power Cable

Trefoil Clamp - Polyamide/Nylon/FRP (Non Magnetic Body & Hardware) suitable for 11kV, 1CX630sqmm Power Cable.

ELECTRICAL PROPERTIES :-

1. TREFOILING is essential for Single core cables 

2. It does nullify the induced magnetic field of high voltage power cable.

3. 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.

4. The 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. 

5. Trefoil Clamps are used for high voltage single core cables where the current rating is high and 3 core cables are not available.
