What Dielectric Sciences does

Dielectric Sciences, Inc. (DSI) is a US-based specialty manufacturer founded in 1970 and headquartered in Chelmsford, Massachusetts. The company designs, manufactures, and tests high voltage cable assemblies, connectors, and insulation systems for applications rated from tens of kilovolts up to the megavolt range. Its product portfolio is organized around five core categories: high voltage interconnect systems (including medical X-ray cables, military cables, commercial/industrial cables, and high energy physics cables with connector variants such as Federal Standard, Mini, Pancake, and Rubber plugs), wire and cable products, cast products for high voltage insulation (tube shields, insulators, transformers, potting), neutron absorbing products (including the proprietary ZHIP Mix boron carbide composite and fiber optically coupled scintillating neutron detectors via the adjacent Brookvine division), and custom products and design solutions. The company's underlying technology rests on proprietary materials expertise across ethylene propylene rubber, silicone rubber, PTFE, and epoxy formulations optimized for extreme temperature, pressure, and radiation flux environments, supported by in-house test facilities and an ISO 9001:2015 certified quality management system.

DSI serves four primary verticals — medical X-ray equipment manufacturers, industrial/commercial users (electron beam welding, ion implantation, down-hole applications), defense/military systems (MIL-SPEC radar, sonar, communications, rail guns, and advanced weaponry), and high energy physics research laboratories. Named customers include GE (original equipment supplier for medical X-ray meeting NEMA XR7 standards), Oak Ridge National Laboratory, Argonne National Laboratory, Rutherford Appleton Laboratory, Hamilton Standard, Leybold Heraeus, and PTR Technologies. The business operates on a sales-led, request-for-quote model with direct customer engagement and custom design consultation. Roughly 1,000 standard product designs are catalogued, most originating as custom solutions. Pricing is not publicly disclosed. DSI is a privately held subsidiary of the High Voltage Technology Group (HVT Group) and is affiliated with HEICO, maintaining CAGE Code 50509 for US government contracting. Distribution is global through direct sales channels, with marketing presence via the company website/catalog, Thomasnet industrial marketplace, and email newsletter.
