Orion Resistor has over 32 years of experience, originating from China’s military industry, and has now grown into one of the leading manufacturers of grounding and protection equipment in China. Known worldwide for its reliability and stable performance, Orion Resistor currently provides safe grounding solutions to more than 60,00 customers across the globe.

Our product portfolio covers a wide range of advanced power system protection devices, including Neutral Grounding Resistor (NGR) cabinets, transformer neutral grounding protection systems, and low-voltage resistor cabinets. Since over 90% of transmission line short circuits are single-phase-to-ground faults, neutral grounding resistors play a critical role by grounding the neutral point through resistance—making them one of the most effective solutions for protecting such equipment.

The Orion Resistor product line is designed for operating voltages from 240V to 132kV and current ratings from 2A to 10,000A. Their performance covers both short-time neutral grounding current as well as continuous static load currents caused by system harmonics and unbalanced conditions. All products comply with the global consensus and unified requirements for neutral grounding equipment, including IEEE Std 32-1972, and can be installed in both indoor and outdoor enclosures with protection levels ranging from IP00 to IP56.

These solutions are widely applied in power plants, substations, utilities, steel, petroleum, chemical, coal, and mining industries, where reliable grounding is essential to safety and system stability.

With a strong R&D and engineering team, Orion Resistor not only delivers proven technology but also provides tailored solutions to meet specific project requirements. Whether your goal is to enhance safety, improve system reliability, or meet international standards, our experts are ready to assist.
