HVR International

What HVR International does

HVR International is a privately-held UK-headquartered manufacturer of high-voltage resistors and related passive electronic components, founded in 1963 at Jarrow, Tyne & Wear. The company produces three core resistor technology families: linear ceramic carbon resistors (a category HVR pioneered globally and has manufactured at Jarrow since 1963), non-linear varistors in both silicon carbide and zinc oxide formulations, and wire- and tape-wound power resistors. The ceramic carbon line is built by pressing and sintering blends of clays, alumina and carbon in a controlled atmosphere, yielding a 100% active material with high energy absorption in a minimum physical footprint; the varistor lines use approximately 90% silicon carbide with ceramic binders, or zinc oxide formulations with extended temperature range up to 125°C.

The group operates four manufacturing/distribution sites — HVR International Ltd (Jarrow, UK, headquarters), HVR Pentagon Ltd (Birmingham, UK, wire-wound and enclosures), HVR International GmbH (Röthenbach an der Pegnitz, Germany, varistors and silico tubes) and HVR Advanced Power Components Inc (Cheektowaga, NY, USA, distribution) — supplemented by a network of 12 regional agents covering France, Italy, Netherlands, Poland, Spain, Switzerland, Turkey, China, India, Japan and South Korea. Products are sold direct and through agents to industrial customers in power transmission and distribution, traction and rail, renewable power generation (wind, solar, storage), electronics, and medical applications, with primary use cases in overvoltage protection, current limiting, dynamic braking, soft-start, and power conversion.

The business model is direct-to-industrial hardware sales with bespoke engineering support: pricing is quote-based against customer specifications rather than list-priced, and HVR provides application engineering assistance to tailor resistors to specific electrical, mechanical and environmental requirements. The portfolio spans roughly 19 distinct product lines including HV Compact Series, Linear Disc Resistors, Rod & Tube Resistors, Silicon Carbide Varistors (disc/rod/tube/leaded), Zinc Oxide Varistors, Wire and Tape Wound Resistors, Mica Wire Wound Resistors, Stud Mounted Resistors, Dynamic Braking Resistors, Power Resistor Enclosures, SR Surge Resistors for PCB mounting, High Voltage Earthing Sticks, and accessories such as Anti-Condensation Heaters and Thermostats/Hygrostats. The company is independently owned with no disclosed external investors or funding rounds.
