Richge is a manufacturer of Switchgear self-locking device in China, specializing in high-precision components designed to enhance the safety and efficiency of medium-voltage switchgear systems. Our Switchgear self-locking device are engineered to provide reliable protection and control, ensuring secure operation in electrical switchgear assemblies. The Switchgear Self-locking Device is a security mechanism used for the electrical switching device, ensuring that the switching device, such as the circuit breaker, isolation switch, and load switch, can maintain the secure state during operation. The device is designed to prevent accidental operation or misoperation and to ensure that the equipment will not be re-operated in the event of power failure or other dangerous situations, thereby improving operator safety and equipment reliability.

Newly developed load break switch, applied on SF6 RMU. With features of high efficiency, safety, reliability, simple structure, flexible operation, interlock reliable, easy to install and so on. It satisfies with standard IEC94, GB3804, GB16926 and so on. The FL(R)N36 Indoor AC High Voltage SF6 Load Break Switch and LBS-Fuse Combination are designed for use in three-phase AC 50/60Hz RMUs (Ring Main Units) and terminal power stations. These switches are suitable for protecting power systems operating at 10kV, 24kV, and 35kV under on-load conditions. They are capable of interrupting on-load current, closed-loop current, no-load transformer capacity, and cable charging current. When equipped with a fuse combination, they can cut off any current within the range of the rated short-circuit breaking current. These devices find application in RMUs and combined transformers, among others.

Electrical Cabinet Hinge: Product Details and Applications The Electrical Cabinet Hinge is a critical component designed to facilitate the smooth operation of electrical cabinets and enclosures. Constructed from high-quality materials such as stainless steel or zinc-plated steel, these hinges are engineered for durability and resistance to corrosion, ensuring longevity even in demanding environments.

Product Introduction: Switchgear Adaptor The Switchgear Adaptor is a crucial component designed to enhance the flexibility and interoperability of electrical switchgear systems. Engineered to connect different switchgear units seamlessly, this adaptor ensures reliable and safe operation across various configurations. It is constructed from high-quality materials, such as robust stainless steel and durable plastics, which provide excellent resistance to corrosion and wear, ensuring longevity even in demanding environments.

SOLH MGQ series ultra-thin integrated guide rod cylinder is fully interchangeable with original SMC specifications. The integrated structure of cylinder barrel and guide rods cuts the overall thickness by 50% compared with conventional guided cylinders to greatly save installation space. It covers bore sizes φ12~100 mm and standard strokes 25~250 mm, offered in two configurations: MGQM carbon alloy slide bearings and MGQL high-precision ball bearings. The symmetrical dual guide rod structure delivers outstanding resistance to lateral load, deflection and torsion. MGQL ball bearing version achieves anti-rotation accuracy of ±0.04°~±0.08°, while MGQM slide bearing type features excellent wear resistance, dustproof performance and cost advantages for heavy-duty dusty conditions. Standard configurations include built-in magnetic rings, dual-end rubber buffers and oil-free maintenance-free operation. The optional XB6 high-temperature variant works steadily up to 150℃. Multiple mounting holes are reserved on the cylinder body; magnetic switches can be mounted on four sides for bores ≥32 mm, and flanges/foot brackets support multi-angle assembly. With a minimum working pressure of 0.1 MPa, it is widely adopted for conveyor line stopper positioning & lifting, PCB ejection and crimping in 3C electronics, gate actuation for packaging machinery and jig jacking. It replaces separate cylinder plus external guide assemblies to simplify mechanical design. Compared with standard MGP and heavy-duty MGG series, MGQ boasts the thinnest profile and optimal performance for high-precision operation in confined installation space.
