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.

The High-Voltage AC Switch for Grounding is a vital safety device in high-voltage power systems, designed to facilitate the grounding and isolation of electrical equipment during maintenance operations. It operates effectively at voltage levels between 12kV and 40.5kV, showcasing robust short-circuit withstand capabilities and reliable mechanical functionality. With its compact design, it ensures straightforward installation and user-friendly operation, making it suitable for high-voltage switchgear and substations. Compliant with rigorous international standards, this grounding switch provides consistent safety and performance in demanding electrical conditions.

SOLH 2S series 2/2-way normally closed fluid solenoid valves include two full lines: direct-acting small orifice 030/050 models and pilot-operated large bore 150~500 variants, for automatic on-off control of clean water, compressed air, cutting coolant, lubricating oil and weakly corrosive liquid pipelines. The direct-acting version enables zero-pressure startup without minimum differential pressure limit, features compact size, universal mounting orientation and millisecond fast switching, ideal for low-pressure micro-flow applications such as single-point machine tool cooling, 3C micro air/water branches and mini cleaning equipment. The pilot-operated type requires a minimum 0.05MPa pressure difference for full opening, delivers ultra-large flow with low-wattage low-heat coils, suited for air compressor drain headers, main spray water lines and high-flow circulating water treatment pipelines. Standard NBR nitrile rubber seals are equipped, with optional acid & hot water resistant EPDM food-grade seals. Multi international thread standards (PT/G/NPT) and global universal coil voltages (DC12/24V, AC24/110/220V) are available, supported by DIN plug and wire lead wiring options. Heat-resistant coils allow long-term continuous energization. Selection guide: direct-acting type for pipelines with static pressure below 0.05MPa and small branch flow; pilot-operated version for G1/2 and above main headers with stable high pressure & large circulation flow. EPDM seal is mandatory for hot water and food-grade fluid media.

SOLH CJP single acting spring return micro pin pneumatic cylinder is fully interchangeable with equivalent SMC models. Bore sizes cover Ø4/6/10/16 mm, including CJP (without magnetic ring) and CDJP (built-in magnetic ring) variants. Single acting design extends under air supply and retracts automatically via spring upon air cut-off with power-off reset safety feature. Without built-in cushion, it delivers rapid response and maximum cycling frequency up to 250 cpm. Two mounting styles are available: panel mount B and flush embedded mount S. The ultra-short body can be embedded inside machinery to save installation space. Hard anodized brass barrel and NBR seals support oil-free clean environment operation with service life over 3 million cycles. Widely used for unidirectional ejection, positioning stop, miniature jig driving, 3C button durability testing and other short-stroke single-direction actuation. A minimum 50% thrust safety margin is recommended during selection. Select CJP2 double acting model for bidirectional push-pull motion, and CJ1 ultra-mini cylinder for ultra-light payload in extremely confined space.

The 3 Phase Connection Support 630A is an essential component designed for efficient electrical connections in medium to high voltage switchgear systems. This support is engineered to handle currents up to 630A, ensuring optimal performance and reliability in demanding environments.
