The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage. It serves as a crucial protective and control unit for power distribution equipment and industrial facilities. This circuit breaker is suitable for environments that require frequent operations at the rated current or the capability to interrupt short-circuit currents multiple times. The circuit breaker features a modular design, where the operating mechanism and the circuit breaker body are separable, allowing for quick replacements and assembly. VSG vacuum circuit breaker is a new indoor switchgear. It is mainly used for three-phase AC power system with rated voltage of 12kV and rated frequency of 50-60HZ. It has the advantages of compact structure, high reliability, small operation vibration and easy maintenance. It can be widely used in power plants, steel mills, metallurgy, petrochemical, transportation, buildings and other industrial and mining enterprises. As a switchgear for protecting high-voltage motors, transformers, line faults and other loads.

SOLH 4M series plate-type 5/2-way solenoid valves strictly comply with international NAMUR mounting standards, purpose-built for direct assembly onto pneumatic actuators driving ball valves and butterfly valves. The integrated bottom base comes with pre-embedded P, A, B, R1 and R2 air passages, enabling seamless docking with actuator air cavities without external tubing for A/B working ports. This streamlined layout drastically cuts pipeline layout workload and potential air leakage points compared with conventional tube-connected 4V series solenoid valves. This lineup adopts internal pilot spool construction with oil-free operation, offered in single-coil spring reset (4M×10) and double-coil latching memory (4M×20) configurations covering three size grades: 4M100, mainstream 4M200 and high-flow 4M300. Single electric control variants automatically reset under spring tension once power is disconnected for fail-safe reset scenarios, while double electric control versions retain their switching position steadily after power cut to sustain valve opening/closing status for long-term pipeline locking. Each unit is fitted with a side-mounted manual override button for convenient offline commissioning and maintenance testing. Coils support widely used global AC/DC voltages with IP65 dustproof and waterproof ingress protection, suitable for rigorous working conditions in water treatment, chemical pipelines and general industrial fluid switching. The series is dimensionally compatible with manifold bases shared with the equivalent 4V series, supporting standalone actuator installation or centralized valve island assembly via multi-station manifolds. With certified standard NAMUR interface, interchangeable with mainstream Airtac 4M series, it serves as a dedicated matched control component for automated on-off regulation of pneumatic ball and butterfly valve actuators.

SOLH HFY Y-type pivot swing pneumatic gripper serves as a cost-effective interchangeable alternative to SMC MHC2. Driven by single piston pivot linkage with lever torque amplification. Two variants are offered: double acting HFY and single acting normally open HFTY. Swing range reaches +30°/-10° with total effective swing angle around 40°. Built-in adjustable throttle valves enable independent speed regulation for opening and closing, and repeat positioning accuracy achieves ±0.02 mm. Bore sizes cover 6/10/16/20/25/32 mm. Three mounting surfaces (bottom, side, rear) are available. Built-in magnetic rings are compatible with CMSH and DS1-G magnetic switches for limit signal feedback. It is ideal for outer wrapping gripping of round, curved and irregular miniature parts under confined installation space and high-frequency light-load handling conditions. During selection, note that clamping torque decreases with extended jaw overhang; a safety factor ≥1.5 is required for load verification. Compared with original MHC2, HFY features slightly narrower swing angle yet supports three-side mounting with superior cost performance. Original MHC2 is recommended if wider swing range or power-off normally closed holding function is required.

GN19-12(C) indoor HV disconnect switch applies to power system of rated voltage 12kV, AC 50/60Hz. It is equipped with CS6-1 manual-operating mechanism and is used to break and make circuit under no-load. There are additional pollution type, high-altitude type and power indicating type. It is made as per IEC 62271-102. The isolating switch of this series is equipped with a CS6-1 manual operating mechanism (the isolating switch with a panel has its own conjoined operating mechanism).   This series of isolating switches is a three-pole type, which consists of a chassis, a rotating shaft, a lever, a porcelain pillar insulator, a knife and a wiring board. The rotating shaft is arranged on the bottom frame, on which three pairs of levers are welded, and the levers pass through the pull rod porcelain insulator and the knife necklace. The rotating shaft extends out of the base frame, and any section of the rotating shaft can be connected with the operating mechanism.   Type C is through the wall. Among them, C1 means that the rotation is on the side through the wall; C2 means that the disconnection is on the side through the wall; C3 means that both sides are on the side through the wall.
