Core Technology and Quality Assurance

Junray Electrical’s High and Low Voltage Components are built upon the core philosophy of "Core Reliability, Comprehensive Assurance." All components are manufactured in strict compliance with national GB standards and international IEC standards. Furthermore, prior to leaving the factory, every single unit undergoes a rigorous, comprehensive inspection process—including precision testing, breaking capacity testing, withstand voltage testing, and insulation testing—to guarantee its stability and reliability.

In-House Manufacturing and End-to-End Quality Control: All components are manufactured entirely in-house. From raw material procurement and production processing to final factory inspection, we maintain autonomous control over the entire value chain. This approach eliminates potential quality risks associated with outsourced parts, ensures component consistency and reliability, and provides a fundamental guarantee for the stable operation of complete equipment sets.

Customization Capabilities: We offer full customization support across our entire range of components. Based on specific client requirements, we can tailor parameters such as rated current, breaking capacity, number of poles, current-carrying capacity, and accuracy class to meet the unique technical demands of diverse projects.

Commercial Adaptability: We offer products in two distinct versions: a generic, unbranded version and a branded "Junray E" version. This dual-version strategy allows us to cater to a wide array of commercial scenarios—including e-commerce retail, equipment integration for complete sets, engineering tenders, and export trade—thereby effectively meeting our clients' specific branding and distribution channel requirements.

FLN36 Sulfur Hexafluoride Switch

For the switching of load currents within ring networks, the high-breaking capacity typically found in circuit breakers is unnecessary. The FLN36 Sulfur Hexafluoride Switch—specifically developed by Junray Electrical for use in ring main units (RMUs)—utilizes SF6 arc-extinguishing technology to deliver robust arc-quenching capabilities. Capable of reliably switching load currents, it offers a significantly lower cost compared to standard circuit breakers. It serves as a perfect match for ring main units and cable branch boxes, establishing itself as the standard switch component for ring network systems.
