Secure your power distribution systems with high-performance NGRs designed for global utilities and industrial plants. We offer customizable specifications, rigorous testing, and reliable FOB/CIF shipping schedules.
A Neutral Grounding Resistor (NGR) is a critical electrical safety component installed between the neutral point of a transformer (or generator) and the ground. Its primary function is to limit the current flowing through the neutral point during a ground fault event to a safe, controlled level.
By controlling fault current, our Neutral Grounding Resistor systems prevent equipment damage, reduce the risk of arc flash hazards, and allow for continuity of service in critical industrial applications.
Inside Our Facility: See our precision resistor winding process and rigorous high-voltage testing lab. Every unit undergoes strict QC inspections to ensure IEEE-32 compliance before crating for export.

"We sourced 15 units of 11kV NGRs for a substation upgrade in Southeast Asia. The build quality matched our strict grid requirements, and the documentation was perfect for inspection."
"Shanghai Powers provided a very competitive lead time compared to European suppliers. The stainless steel enclosures have held up well in our coastal facility."
"Reliable partner for high-voltage resistors. Their engineering team helped us customize the current ratings to fit our legacy systems. Consistent quality."
Standard manufacturing time is 4-6 weeks depending on the complexity and quantity. For urgent project timelines, please consult our team regarding expedited production slots.
Yes, we specialize in tailor-made solutions. We can manufacture NGRs for systems ranging from 0.38kV to 110kV with custom resistance values, current ratings, and enclosure protection levels (IP23-IP54).
Our manufacturing process adheres to ISO 9001 standards. Our resistors are designed to comply with major international standards such as IEEE-32 and IEC 60076, ensuring safety and reliability.
We typically operate on FOB Shanghai terms but can arrange CIF or DDP upon request to major global ports. All units are crated in export-grade packaging to prevent transit damage.
Our MOQ is 1 unit. We support both single-unit orders for specific project needs and bulk orders for distribution or large-scale infrastructure development.
Yes, every order includes a comprehensive documentation package, including GA drawings, electrical schematics, and operation/maintenance manuals in English.
