Switchgear copper bolts are critical components in electrical switchgear assemblies, designed for high conductivity and mechanical strength. Made from high-purity copper, these bolts ensure excellent electrical performance and durability. The bolts feature a robust construction with precise threading to ensure secure connections and optimal contact with other components. They are commonly plated to enhance resistance to corrosion and wear, ensuring longevity in various operational environments. Switchgear copper bolts are available in various sizes and configurations to meet specific design requirements and are subjected to rigorous quality control to guarantee reliability and performance.

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 RSQ fixed-height pneumatic stopper cylinders serve as standard limit actuators for automated conveyor systems. Equipped with ten interchangeable rod ends including hydraulic buffer lever styles for heavy shock absorption, they support four-side magnetic switch fitting and oil-free long-cycle operation. Differing from height-adjustable RSG models, its fixed rigid frame cuts on-site debugging time greatly. Our stable mass production ensures sufficient spot stock; these stoppers are widely deployed on electronics assembly lines, roller conveyors and heavy pallet positioning stations globally, delivering reliable workpiece blocking with affordable cost and strong impact resistance.

The Switchgear Connector Ring is an essential component in electrical switchgear systems, designed to ensure a secure and reliable connection between various parts of the switchgear assembly. Made from high-quality conductive materials such as copper or aluminum alloys, the connector ring is engineered to withstand high electrical loads and provide excellent conductivity. Its robust design minimizes the risk of electrical resistance and overheating, which are critical factors in maintaining the efficiency and safety of electrical distribution systems.
