Founded in 1970 in response to a growing need for superior high voltage cable connecting systems, DSI has evolved as a full service provider of high voltage insulation systems. We design, manufacture, and test using problem solving expertise based on solid engineering concepts and years of empirical experience. DSI is a resource for those with exacting and difficult high voltage cable, connector, and assembly requirements as well as exotic material needs, for example, neutron absorption and shielding products.
DSI is a subsidiary of the HVT Group (www.hvtgrp.com), which is majority owned by HEICO Corporation (www.heico.com), NYSE symbol HEI.
