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.

SOLH HSV series 3/2-way hand slide pneumatic valves adopt an inline sleeve push-pull integrated structure, fully consistent with the dimensional specifications of mainstream AirTAC HSV series and interchangeable with equivalent domestic counterparts. Designed without return springs and equipped with mechanical self-locking positioning, this valve switches airflow by axial pushing and pulling: pushing the sleeve forward connects the P inlet port and A working port for normal air supply; pulling backward disconnects the air intake and automatically links port A with the built-in R exhaust port to rapidly vent residual pressure inside rear pipelines and actuators. It serves as a dedicated safety shut-off switch for pneumatic branch pipelines and essential pressure relief valve for equipment maintenance work. Three standard ports are configured: P for main compressed air inlet, A for output to downstream pneumatic components, and an embedded built-in R exhaust port hidden inside the valve body. A wealth of specifications covering G1/8 up to G1 thread sizes are supplied, paired with three thread layout options (SF single inner & single outer thread, SS double outer threads, FF double inner threads); PT taper thread, G parallel thread and NPT thread are selectable to fit global piping standards. Constructed with hard-anodized aluminum alloy valve bodies, stainless steel anti-rust spools and high-performance NBR nitrile rubber sealing rings, the valve supports lubrication-free operation under filtered compressed air within 0~1.0 MPa rated working pressure and withstands test pressure up to 1.5 MPa. The operating push-pull force is controlled at 18~25 N for smooth operation, and the mechanical locking structure maintains the set position firmly without drifting or air leakage caused by accidental touching. Different from 4HV rotary hand valves used for forward/backward switching of double-acting cylinders, the HSV series is engineered exclusively for pipeline on-off and pressure release. It can be directly installed in series within air pipelines without extra mounting bases to save installation space. Widely deployed for isolating air supply before equipment overhaul, main air circuit safety cut-off of automation tooling, vacuum pipeline switching and branch circuit independent air source control, it effectively eliminates hidden dangers brought by residual pressure during maintenance and guarantees on-site operational safety.
