Fiber Glass Trefoil Clamps

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.

Sumip Trefoil Clamps 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.

Sumip Trefoil clamps have been molded from virgin glassfiber filled material.

Sumip Type TRE 28 Trefoil clamp has been tested satisfactorily at CPRI to withstand 50 KA short circuit fault current with spacing between Trefoil clamps kept at one meter distance.

High Mechanical strength, long service life, not affected by all chemicals, acids & alkalies. Design gives good grip on cable.
