China HV Air Load Break Switch with Fuse Manufacturer, Supplier, Factory

The Switchgear Door Pin is a critical component designed for securing various elements within switchgear assemblies. Crafted from high-grade steel or stainless steel, this pin ensures durability and reliability in demanding electrical environments. The locking pin features a precision-engineered mechanism that guarantees a secure fit, preventing accidental disengagement or movement of switchgear components during operation.

SOLH IL100 booster relay is fully interchangeable with equivalent SMC models, acting as a 1:1 equal-pressure precision pneumatic volume amplifier. It achieves precise pressure tracking between input signal and output with linearity error within ±1% FS and maximum flow up to 6000 L/min, effectively eliminating slow response lag from long pipelines, large diaphragm actuators and big bore cylinders. Multiple thread standards including Rc, NPT and G are available. Besides standard temperature version, low-temperature (-30℃), high-temperature (100℃) and copper-free high-purity variants for semiconductors are optional. The anti-corrosion aluminum alloy body supports direct mounting or bracket installation with low steady air consumption. Widely matched with positioners for process control valves, long-distance instrument air lines, heavy lifting/clamping cylinders and high-precision positioning loops; copper-free version fits semiconductor high-purity inert gas systems.

SOLH CM3 short stainless steel mini cylinders are upgraded compact replacements for traditional CM2 series pneumatic actuators. Constructed entirely from 304 stainless steel, they deliver outstanding rust and weak acid-alkali corrosion resistance suitable for food, pharmaceutical and clean workshop environments. Optimized structure shortens overall length by up to 29mm and cuts weight by 21%, paired with four-directional air ports to enable flexible multi-angle installation in narrow equipment space. Multiple variants including double-acting, spring single-acting, double-rod and anti-rotation piston rod meet diverse linear drive requirements; CDM3 magnetic version supports magnetic switch sensing for PLC automatic interlock control. Low-friction oil-free sealing ensures over 8 million stable operating cycles. Our factory maintains mass production and sufficient spot inventory, widely applied in medical packaging, electronic assembly and food processing automated positioning.

The VSG-12 indoor high-voltage vacuum circuit breaker is designed for use in indoor switchgear applications within 12kV power systems with a three-phase AC 50Hz rated voltage.
