Vacuum circuit breaker is the most commonly used type of high-voltage circuit breaker, mainly divided into two kinds of indoor and outdoor. We mainly focus on indoor vacuum circuit breakers. (Indoor circuit breakers: High-voltage circuit breakers that do not have the performance of protection against wind, rain, snow, ice and dense frost, etc. and are suitable for installation and use inside buildings.) The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network. The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts. Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.

Richge is a manufacturer of Switchgear Ground Interlocks in China, specializing in advanced interlocking systems designed to enhance the safety and reliability of electrical switchgear assemblies. Our ground interlocks are engineered to ensure that switchgear components are properly grounded before operation, preventing potential hazards and improving operational integrity.

SOLH XTO674 and INA14 inline check valves share the same structural platform with ultra-low 0.01MPa cracking pressure, compatible with both compressed air and clean water for anti-backflow protection in vacuum and low-pressure fluid pipelines. XTO674 is an all-brass cryogenic version working down to -30℃; INA14 standard series provides brass or SUS304 stainless steel body, equipped with standard NBR seals plus optional oil & high temp resistant FKM and weather-proof CR seals. Compact inline threaded design with flow arrow marking can be directly mounted in pipelines without extra brackets, effectively preventing vacuum loss and reverse airflow when installed between vacuum generators and suction cups. The two series feature identical overall dimensions and thread sizes for direct field interchange without pipe modification, widely applied in cryogenic equipment, vacuum production lines, corrosion-resistant high-temperature fluid circuits and general pneumatic & water pipelines for one-way pressure retention and backflow prevention.

Switchgear Static Contact produced by Richge is one of the core components in electrical switchgear. The static Contact is generally fixed in the structure of the switch cabinet, connected with the external circuit, and used with the Moving contact (Moving Contact) to connect and disconnect the circuit. Static contacts play a vital role in the power system, ensuring the safe and efficient operation of electrical equipment. It is one of the key components in switchgear for current conduction and on-off operation.

SOLH IS10 non-contact reed tube pneumatic pressure switch is fully interchangeable with matching SMC air service unit accessories. It operates via air pressure driving a magnet-equipped piston to trigger the reed tube magnetically, featuring zero mechanical contact abrasion and no electric sparks, with far longer service life than IS3000 piston micro-contact switches. The adjustable pressure range covers 0.1~0.6 MPa and hysteresis is controlled under 0.08 MPa. A side graduated viewing window allows offline pressure calibration with a screwdriver without power supply. Two mounting types are available: IS10-01S with R1/8 inline thread, and clip-on IS10M which fastens directly onto AC FRL manifolds to save cabinet space. Rated contact load reaches 1A for AC/DC 100V, capable of directly driving miniature solenoid valves or connecting to PLC digital inputs. Miniature and lightweight, it serves as a cost-standard pressure monitor for main air low-pressure alarm, cylinder full-stroke confirmation and safety interlock of vibrator pneumatic circuits.
