Why Choose Niuni Electric Safety Solutions?

Our locking systems undergo rigorous testing to meet international safety standards, providing peace of mind for site operators and maintenance teams.

Technical Support & FAQs

Our products are designed and manufactured in strict compliance with major international standards, including IEC 62271-100, IEC 62271-200 and IEEE C37.04 standards. All products are inspected by our Quality Control department.

We specialize in the medium-voltage range. Our vacuum circuit breakers and switchgear components are suitable for rated voltages from 7.2kV to 40.5kV. The normal current rating covers up to 4000A, and the short-circuit breaking capacity can be designed up to 40kA or higher to meet the demands of various applications, from simple distribution to heavy industrial use.

 Yes, customization is one of our core strengths. We understand that compatibility with existing equipment is critical. We offer OEM and ODM services and can customize components (like brackets, linkages, shutters) and modify breakers to be compatible with major switchgear brands such as Siemens, ABB, Schneider, GE, and others. Please provide your technical drawings or specifications for a precise solution.

Our quality assurance is embedded in every step of the process:

Material Sourcing: We use premium-grade raw materials and components from certified suppliers.

Manufacturing: Advanced CNC machinery and automated production lines ensure precision and consistency.

Testing: 100% routine tests (e.g., contact resistance, mechanical operation, HV withstand) are performed on every unit. We also conduct destructive and non-destructive tests on samples.

For standard products, our lead time is typically 1-4 weeks. For large or customized orders, the lead time will be confirmed based on the project's complexity and quantity.

Certainly. We provide comprehensive pre-sales and after-sales technical support. Our team of engineers can assist with product selection, technical drawings. We also offer detailed documentation, including manuals and drawings. In the rare event of an issue, we provide remote troubleshooting and have a efficient warranty claim process.

Our vacuum circuit breakers are engineered for superior performance and reliability, offering these key benefits:

High Breaking Capacity: Advanced vacuum interrupter technology ensures reliable interruption of high short-circuit currents.

Long Electrical and Mechanical Life: Designed for thousands of operations with minimal maintenance, significantly reducing life cycle costs.

Maintenance-Free Operation: The sealed vacuum interrupters eliminate the need for regular maintenance of the quenching medium, unlike oil or SF6 breakers.

Safety and Environmental Friendliness: They operate silently, are fire-safe, and contain no greenhouse gases (SF6), making them an eco-friendly choice.

Compact Design: Allows for space-saving switchgear designs, which is ideal for retrofitting or modernizing existing substations.

Our products are designed for global deployment. Please specify your environmental conditions for the most suitable product recommendation.

We stand behind our products with a standard 12-month warranty from the date of shipment, covering any defects in materials or workmanship under normal use and service conditions. Our warranty terms are clearly stated in our commercial contract.
