The indoor High-Voltage Grounding Device is a safety protection device designed for high-voltage power systems, used to effectively isolate electrical equipment from the grid and ground it, ensuring the safety of personnel and equipment during maintenance or inspection. This product is typically suitable for voltage levels ranging from 12kV to 40.5kV, with strong short-circuit current withstand capabilities and reliable mechanical operation performance. Its compact structure, easy installation, and flexible operation make it widely applicable in high-voltage switchgear and substations. Designed to meet both national and international standards, it ensures long-term stable operation in complex power environments.

SOLH MY1B mechanically jointed basic rodless cylinder achieves full interchangeability with corresponding SMC models. Equipped with inner sealing belt and outer dust-proof belt, it cancels the external piston rod, whose overall installation length is close to effective stroke and saves more than 50% layout space compared with tie rod cylinders. Bore sizes range from φ10 to 100mm with maximum stroke up to 5000mm. The slide table is rigidly connected with the piston with outstanding bending resistance, allowing direct load mounting without auxiliary guides under light loads. Four-direction piping (front, rear, side, bottom) is available; models φ25~40 realize 17% weight reduction. Standard built-in adjustable air cushions are equipped, with optional external hydraulic buffers and dual-end stroke adjusters. Pre-reserved grooves fit D-M9 series magnetic switches, and oil-free operation is supported for clean workshops. Classified by load capacity: φ10~20 for light duty, φ25~40 for medium-light duty, φ50~63 for medium duty, φ80~100 for heavy duty. Widely applied in long-distance material conveying, automatic door actuation, heavy workpiece shifting in machining and long-stroke positioning pushing on non-standard automation lines as an economical universal linear driving solution.

The Switchgear Bus Support Insulator is a critical component designed to ensure the reliable and efficient operation of electrical switchgear systems. This high-quality insulator is engineered to provide robust support and electrical insulation for busbars, which are essential for distributing electrical power within switchgear assemblies.

SOLH SY series pilot-operated 5-port solenoid valve is fully interchangeable with matching SMC valves, including SY3000 mini, SY5000 medium mainstream, SY7000 large and SY9000 extra-large models. It provides complete circuit options: 5/2 single/double coil and 5/3 three-position with center closed, center exhaust & center pressure supply functions. Standard 0.35W coils and optional 0.1W ultra-low power energy-saving coils generate little heat for continuous energization. Internal pilot version works 0.1~0.7 MPa, while external pilot variant supports -100kPa vacuum environment. The gap-sealed spool reaches up to 200 million switching cycles. Air ports are arranged on side, top and bottom for flexible tubing routing. Valves adopt plug-in snap design compatible with SS5Y manifold valve islands, enabling single-valve maintenance without disassembling the whole bank, with IP65 plug connector and IP67 manifold base rating. Optimized internal runners deliver around 80% higher flow than legacy valves, and built-in pilot filter mesh prevents spool stuck by dust. Widely used for cylinder directional switching and centralized pneumatic control in semiconductor, automotive welding, packaging and medical automation equipment.
