Clamps and Support Systems

Cable clamps can be used for solid dielectric and low pressure oil-filled cables. Typical installation applications include: vertical shaft, termination support, riser pole, tunnel, seismic, manhole/duct entrance, cable tray, and wind towers.

hvGrid-tech supplies aluminum clamps and  id-Technik fiberglass clamps for a variety of power cable clamping applications.  We can also provide custom designed cable support systems for manholes and terminal support structures, as well as custom clamping solutions for special applications.

Aluminum Clamps

hvGrid-tech’s cast aluminum clamps are available in five different cable diameter ranges. Each clamp is supplied with stainless steel mounting bolts and neoprene liners. Optional stainless steel springs are available to allow for expansion and contraction of the cable, while maintaining adequate holding force to secure the cable.

Other specialty types of clamps can be custom designed to suit the customer’s specific cable dimensions and/or special installation requirements including single point mounted clamps and multi-cable clamps.

hvGrid-tech is the North American exclusive distributor of id-Technik cable clamps for all types of single and multi-core cables from extra high to low voltage. id-Technik  was the first manufacturer to develop short-circuit-proof cable clamps made of high-quality polyamide and these are now used around the world.

These clamps are ultraviolet ray protected, flame resistant and free from halogens. Mounting hardware and elastic inlays are optional items.

id-Technik cable clamps have been type tested to IEC 61914 and are made in Germany at an ISO 9001 certified facility. They have been installed for more than 40 years in more than 120 countries.
