LW-126 type outdoor high voltage alternating current sulfur hexafluoride circuit breaker (hereinafter referred to as the circuit breaker) is a kind of outdoor high-voltage switchgear equipment with three poles AC SOHzand it adopts SF6 gas as arc extinguishing and insulation medium. It can be used for the separation and combination of rated current and fault current, capacitor bank, and switching circuit, and it can also be used as aninterconnecting breaker so as to realize the control and protection of transmission lines and equipment, especially suitable for frequent operation.The circuit breaker is equipped with CT20 type spring operation mechanism.This circuit breaker complies with the requirements of IEC 62271-100. Lw36-126 3150-40 self-energized Ac high-voltage sulfur hexafluoride circuit breaker is an outdoor product, suitable for altitudes not exceeding 2,ooo meters (products can be designed for altitudes above 3,ooo meters), and the ambient temperature is not lower than -40°c. In the Ac 50Hz power grid with a maximum voltage of 126KV in areas with a pollution level no higher than Level Iv, it is used to cut off rated current, fault current or conversion lines to achieve power control.For system control and protection, it can also be used as a contact circuit breaker This product uses sF6 gas as arc extinguishing and insulating medium, adopts the most advanced self-energy arc extinguishing technology in the world, and is equipped with a new spring operating mechanism. It has the characteristics of long electrical life, low operating power, low noise, and high reliability., with its simple structure, small size and long maintenance cycle, it can completely replace the same type of imported products in the current process of oil-free and large-capacity power equipment.

SOLH CU/CDU rectangular free mount cylinder features ultra-thin block structure with multi-surface mounting holes, enabling multi-angle direct installation without brackets to save equipment space. Complete variants include non-magnetic CU, magnet-equipped CDU, CDUK non-rotating rod and CDUW double guided rod models. Bore sizes φ6~32mm, available in single/double acting types with fixed rubber buffers on both ends for continuous oil-free operation. CDU series is compatible with CMSH and DMSH magnetic switches for position detection and tolerates partial side load. Widely used in 3C & semiconductor jigs, automation stoppers, light clamping positioning and small press-fit mechanisms for compact automated equipment.
