Trefoil Clamps / Cable Cleats are used for laying single core cables in Trefoil touching formation which helps to maintain magnetic symmetry thereby avoiding electromagnetic heating and loss of current.
Trefoil clamps have been manufactured by molding process from Virgin Glass Filled materials. Glass filled materials are used to increase the flexibility of the clamp & to avoid the breaking the clamps from the hook while the tightening procedure of the three single core cables
Trefoil clamps are used for high voltage single core or higher sizes cables where the current rating is high & 3 core cables are not available.
