Cable clamp/cleat is a device designed to provide securing of cables when installed at intervals along the length of the cables.” (IEC 61914). PTE's single & trefoil clamps made of non-ferrous, non-magnetic alloys meets the requirement of latest international standards & type tested for electrical short circuit, axial load, lateral load and impact as per stringent requirements of IEC 61914.

Our clamps are provided with all the required installation hardware, like nuts, bolts, washers, and springs. EPDM rubber lining is used with the clamps to increase friction resistance, & to accommodate the expansion of XLPE during heating/cooling cycles due to varying loads& ambient temperature variations.

Cable clamps are designed to hold cables in Flat and trefoil formation in normal operating conditions and restore cable geometry after experiencing severe loads & short circuit which may result in damage of terminations/sealing ends.

Selection of right clamps with adequate strength is the most important factor to overcome a fault and enable the circuit to be restored once the fault has been repaired. The proper clamping is important ensures easy installation and the safe long term performance of the cable system.

When parallel conductors carrying 3 phase alternating current suffer a short circuit fault, the cables experiencing extreme opposing forces. Hence it is very important to have a proper cable support and clamps design to ensure the safety of cable at transient switching and faults.
