Core Product Series

Precision‑Built Equipment for Reliable Power

( 01 ) Indoor High-Voltage Vacuum Circuit Breaker Series

Our indoor high-voltage vacuum circuit breaker series is primarily used in the indoor power distribution systems of industrial/mining enterprises, power plants, and substations, serving as the core protection and control device for switching load and fault currents. The range covers fixed, handcart, side-mounted, and three-position vacuum circuit breakers, with voltage ratings from 12kV to 40.5kV. Featuring an integrated sealed pole column design, the breakers achieve compactness, high reliability, and maintenance free operation, with a mechanical life of up to 20,000 operations — suitable for frequent-switching applications. They are compatible with switchgear such as KYN28 and XGN series, and customized production and technical selection advice are available based on cabinet dimensions, operating voltage, and control mode.
( 02 ) 12kV Medium Voltage Complete Switchgear Equipment

Our 12kV medium voltage complete switchgear equipment is widely used in urban distribution networks, industrial/mining enterprises, and renewable energy grid-connection sites. The product range covers fully insulated, fully sealed ring main units, solid insulated switchgear, air-insulated ring network cabinets, and box-type fixed/removable enclosed switchgear, meeting a variety of budget and installation requirements. Featuring advanced insulation technology and compact design, the equipment is small in size, maintenance-free, and highly reliable — ideal for space-constrained distribution rooms and outdoor ring network points. We offer end-to-end service from selection consultation and drawing design to manufacturing and on-site commissioning, helping customers quickly build a safe and stable distribution system.
( 03 ) Transformer Series

Our transformer series is applied in grid transmission & distribution, industrial/mining power supply, and renewable energy power stations, covering fully sealed oil-immersed distribution transformers, single-phase pole-mounted transformers, S22 series medium/high voltage distribution and power transformers, 220kV three-phase on-load voltage regulating transformers, and dry-type epoxy cast transformers, with voltage ratings from 10kV up to 220kV. Made with high-quality silicon steel sheets and oxygen-free copper wire windings, the transformers offer high efficiency, low loss, and maintenance-free operation, with some models certified as national high-tech products. Customization is available based on the customer's regional voltage standards, capacity requirements, and installation environment (indoor/outdoor, oil-immersed/dry-type), along with comprehensive transportation, installation guidance, and after-sales service.
( 04 ) Low Voltage Complete Electrical Equipment

Our low-voltage complete electrical equipment is mainly used in industrial plants, commercial buildings, and residential communities for low-voltage distribution and power quality management. The range covers draw-out/fixed type low-voltage switchgear, capacitor compensation cabinets, active filter cabinets, comprehensive distribution cabinets, and various AC distribution boxes — covering the full scope from main distribution to end-point distribution. We emphasize safety and intelligence; some products integrate digital fire-inspection functions for remote monitoring and fault warning. Manufacturing strictly follows standards such as GB/T7251, with customized configurations available based on load, circuit quantity, and installation environment.
