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 HLH ultra-thin side L rail linear slide cylinder adopts integrated single-side recirculating ball guide rail with slim low-profile body to save installation space, a double-acting pneumatic slide dedicated to light-load precision positioning. Bore sizes range from 6, 10, 16 to 20 mm with standard strokes of 5–60 mm, operating pressure 0.15~0.7 MPa and working temperature from -20℃ to 70℃. The cylinder body features 4-direction mounting tapped holes and 3-side air ports for flexible piping layout. The slide carriage is equipped with fixture tapped holes and positioning pin holes on top and front surfaces. A built-in magnetic ring comes as standard, with dual side slots for mounting magnetic reed switches. The floating joint between piston rod and carriage eliminates lateral side load and ensures excellent straightness & anti-rotation precision. Compared with twin-rail HLQ series, HLH features slimmer outline for confined narrow space, widely applied in 3C & semiconductor mini inspection jigs, light-duty push-clamping units and reciprocating positioning mechanisms inside compact automation machinery.

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.

Switchgear Limiting Block: Product Details and Applications The Switchgear Limiting Block is a crucial component designed to enhance the safety and efficiency of electrical switchgear systems. Constructed from high-grade insulating materials, it ensures durability and resistance to electrical stress, heat, and environmental factors. The limiting block is typically used in medium and high voltage switchgear to limit the movement of switchgear drawers, thereby preventing accidental disengagement during operation.
