The VSM-12 vacuum circuit breaker integrates a permanent magnet operating mechanism and a vacuum interrupter in a front-and-rear configuration. The breaker features a draw-out type design with a fixed arc-extinguishing column (solid sealing poles) and is designed for high reliability and performance in demanding electrical environments. The permanent magnet operating mechanism and the vacuum interrupter of the VSM-12M vacuum circuit breaker adopt front and rear arrangement. The main conductive circuit is a floor-standing structure. The upper and lower outlet seats and the vacuum interrupter are installed in an embedded pole Inside. The embedded pole is made of epoxy resin by APG process. This structure can prevent dust accumulation on the surface of the vacuum arcing chamber and prevent it from being damaged by external factors. It can ensure that the product still has good insulation performance in the humid and hot environment and serious pollution.

ZN12-12 series indoor AC HV vacuum circuit breaker is the indoor equipment of three phases AC 50Hz, rated voltage of 12kV, which introduced the technology from German company. It is suitable for area with all kinds of load and frequent operation, and can used for protection and control of industrial and mining, enterprise, power plant and substation electrical facilities. This product is in accordance with related requirement of GB1984, JB3855, DL403 and IEC standards.

VBA pneumatic booster valves are power-free air amplifiers built on self-developed piston area difference boosting technology, delivering stable 2× and 4× pressure amplification with matched VBAT air tanks for instant high-pressure airflow. Fully pneumatic automatic cycling ensures explosion-proof & energy-saving performance, while built-in buffers cut noise and extend service life to over 50 million cycles with easy installation. We maintain sufficient stock of 5L-38L air tanks with growing annual sales. Widely adopted for cylinder clamping reinforcement, riveting, dispensing and mold high-pressure blowing, they offer a cost-effective local boosting alternative without upgrading whole plant air systems.

Richge Technology compact energy-saving VBA pneumatic booster regulator adopts self-optimized high-efficiency boosting air circuit independent R&D technology, cutting air consumption effectively.
