Switchgear Limiting Block: Product Details and Applications The Switchgear Limiting Block is a crucial component designed to enhance the safety and efficiency of electrical switchgear systems. Constructed from high-grade insulating materials, it ensures durability and resistance to electrical stress, heat, and environmental factors. The limiting block is typically used in medium and high voltage switchgear to limit the movement of switchgear drawers, thereby preventing accidental disengagement during operation.

VSG indoor high voltage vacuum circuit breaker  is used for 24KV power system indoor switching equipment, as power grid equipment, industrial and mining enterprises power design protection and control unit VSG-24C type Side installation Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker

SOLH MSZ three-position rack-and-pinion pneumatic rotary cylinders are dedicated rotary actuators engineered to achieve three-point locking positioning (left limit / intermediate stop / right limit), solving the limitation of conventional two-position rotary cylinders lacking mid-station positioning. This series only needs one 5/3-way center-pressure solenoid valve for full position switching, removing complicated dual-valve pneumatic circuits to simplify system layout and lower overall engineering costs. The intermediate locking position supports ±10° fine angular adjustment, while the left and right travel limits are separately tunable within 0~95°, delivering flexible multi-angle positioning. It is classified into four specifications: basic MSZB, high-precision MSZA, rubber buffer MSZB-R and hydraulic buffer MSZA-R. The dual-rack dual-piston internal structure effectively eliminates gear backlash and outputs steady torque during frequent position switching. The integrated rotary plate comes with reserved locating pin holes for direct workpiece installation, paired with a central hollow through-hole to pass wiring and air tubing neatly. Standard side sensor grooves fit D-M9B & D-A93 magnetic switches to realize real-time signal feedback of three working stations. MSZA boasts positioning accuracy up to ±0.02 mm, while hydraulic buffer variants absorb large collision energy perfectly for high-speed heavy-duty rotation. Adopting oil-free self-lubricating design for long-term stable running, this rotary cylinder is widely deployed in workpiece sorting diversion, multi-station indexing, electronic positioning inspection and packaging automated steering flip procedures.

FLN48-12 load break switch use SF6 gas as arc extinguishing and insulating medium. There are three work stations: opening, closing and grounding in the switch. It has small volume, installing easy-to -use, strong environmental adaptabiliy and other characterist.. It is also for the control and protection of substation and equipments; making and breaking short-circuit current under various operating status of electric network and its performance indicators meet the national standard GB/T3804-2017 "3.6kV-40.5kV high-voltage AC load switch", which is the main switching element of the ring main unit.
