China Switchgear Interlocking Accessories - Durable Bevel Gear Manufacturer, Supplier, Factory

The Switchgear Drawer Mechanical Interlock is a crucial safety feature designed to enhance operational security in electrical switchgear systems. This interlock mechanism prevents unauthorized or accidental operation of the drawer, ensuring that the switchgear remains in a safe state during maintenance and operation.

SOLH IP200 force-balance nozzle-flapper all-pneumatic servo positioner converts 0.02~0.1MPa air control signal into precise cylinder linear displacement without power supply, delivering intrinsic explosion safety for chemical, mining and flammable environments. It achieves high control precision with sensitivity ≤0.5% FS, suitable for double-acting cylinders with bore ≥Ø50mm and stroke 25~300mm. Integrated all-in-one design mounts directly on cylinders, equipped with separate zero and span adjustment screws for tool-free on-site calibration. Carbon steel or stainless steel feedback springs are optional, alongside low and high temperature customized variants. The supply air must be dry and filtered within 5μm. Widely applied in precision press-fitting, coating, web tension & edge correction, valve stroke regulation and fully pneumatic servo positioning explosion-proof equipment.

ZW32-12 (FDGM) series outdoor high-voltage vacuum circuit breakers (hereinafter referred to as "circuit breakers") are outdoor distribution switchgear with a rated voltage of 12KV and three-phase AC 50Hz. Circuit breakers are mainly used for breaking and closing load current, overload current, and short circuit current in power lines. They have overload and short circuit protection functions, meet control and measurement requirements, and can also achieve remote control and monitoring functions. They are widely used in substations, industrial and mining enterprise distribution systems as control and operation purposes, especially suitable for places that require frequent operation. The circuit breaker complies with technical standards such as GB1984-2003, DL/T402-2007, and IEC60056.It is also used in rural power grid places with frequent operation for breaking and dlosing the load current and over load curent and short circuit current of power system，It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in substation and industrial and mining enterprise substation systems, and places where rural power grids operate frequently.

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 MHT2 toggle-joint heavy-duty self-locking pneumatic gripper is fully interchangeable with equivalent SMC models. The toggle linkage dead-point structure amplifies clamping force by 3~5 times. Mechanical self-locking engages once fully closed, retaining over 80% clamping force after air loss to prevent workpiece dropping, ideal for overhead robot handling and high-safety stations. Bore sizes cover 32/40/50/63 mm, offered in standard D type and updated lightweight DZ variant. Magnetic switches (M9BW) can be mounted on four sides for flexible sensor arrangement. Equipped with high-strength alloy steel jaws and wear-resistant linkages, it supports long-term oil-free continuous operation. Swing angle is limited within 23°~28°, so workpiece clearance must be verified during selection. Widely used for automotive components, cast & forged parts, heavy-duty machine tool loading and safety fixtures for pressing equipment. Unlike ordinary parallel grippers without locking function, MHT2 is the preferred solution for heavy loads requiring anti-drop protection.
