GW4-12(40.5) Outdoor HV Disconnect Switch GW4-12(40.5)outdoor AC high voltage disconnect switch (disconnect switch for short) is used to open and close circuit with voltage but no-load 50/60Hz, 12(40.5)kV power system. It accords with standards of IEC129-1984 AC Disconnect Switch and Earthing Switch and GB1985 and other relative standards.

The Ground Switch Mechanism for Switchgear is a safety mechanism designed to prevent the accidental operation of a ground switch in electrical systems, such as switchgear, transformers, and circuit breakers. It ensures that the ground switch can only be operated under safe conditions, typically when other switches, such as circuit breakers or isolators, are in the correct position. This interlock device is crucial for preventing the grounding of equipment while it is still energized, thereby reducing the risk of electrical accidents and ensuring the safety of maintenance personnel. The device typically works by physically preventing the operation of the ground switch unless certain conditions are met, such as ensuring that the disconnecting switch is open or that the equipment has been properly isolated from the power supply. In some designs, the interlock may also include status indicators or alarms to signal whether the conditions for grounding are safe. The Ground Switch Interlock Device is commonly used in substations, power plants, and industrial electrical systems where high-voltage equipment is present and maintenance work needs to be performed safely. It enhances operational safety by preventing errors in the grounding process, ensuring that equipment is properly isolated and grounded before work begins. By incorporating interlocking mechanisms, the device helps to streamline maintenance procedures, minimize human error, and improve the overall reliability of the electrical system.

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.

SOLH MBB lightweight tie rod standard cylinder is an upgraded lightweight model, 10% lighter than traditional MB series and fully compliant with ISO15552 standards for direct replacement of imported tie rod cylinders. Featuring double-end adjustable air cushion and square end caps, it ensures high rigidity, low noise and stable oil-free operation, suitable for medium-load and high-frequency working conditions. It covers multiple variants and diverse mounting options, widely used in conveying equipment and general automation machinery. With mature mass production and sufficient stock, it supports stable batch supply and exports worldwide.

SOLH CJP2 compact double acting pin pneumatic cylinder is fully interchangeable with equivalent SMC models. Bore sizes include Ø4/6/10/16 mm, split into CJP2 (without magnet) and CDJP2 (built-in magnetic ring). Pure double acting design fitted with rubber cushions on both ends to reduce impact and noise. Compared with legacy CJP series, it adopts shorter body construction and achieves 55%~65% weight reduction. Six mounting styles are available: basic, panel, flange, foot mount and more, suitable for embedded installation, axial fastening and lateral assembly. All sizes come with magnetic rings; even the minimum Ø4 variant supports dual M9 series magnetic switches for bidirectional position feedback. Hard anodized aluminum barrel and NBR seals enable oil-free operation with service life over 3 million cycles and steady bidirectional thrust. Widely used for short-stroke bidirectional push-pull applications such as micro component ejection in 3C industry, button durability testing, precision instrument fine-tuning and miniature actuators for medical equipment. A minimum 30% load safety margin shall be reserved during selection. Choose single-acting CJP if spring return is required, and CJ1 ultra-mini cylinder for extremely confined ultra-light load space.
