Product Description

Xusheng is an industry leader in vacuum interrupters, offering environmentally friendly medium and high voltage interrupters that reliably switch high stress currents robustly without the need for unreliable cooling or ventilation systems. Vacuum interrupters provide long life and low maintenance, save space, and reduce costs. Used for repetitive switching, motor inrush current interruption, fault protection, and overcurrent and short circuit protection.

The following drawing shows the Basic structure of vacuum switching tubes. Out can, which is cylinder made by ceramic, and two metal covers seal a container. There are two contact heads in container, a stationary head fixed on the end of the stationary conductive pole and a moveable head fixed on the end of the moveable conductive pole. The moveable conductive pole pass through the center hole of the bellow and the metal cover. The bellow, which is brazed to the middle of the moveable conductive pole on one end and brazed to the metal cover on the other end, is a stretchy part can flex axially as its wavy side.

Vacuum switching tubes can be sorted by utilization, for breaker, for load switches, for contactor and for special utilization. Vacuum switching tubes for breaker should be capable to break short circuit current, which is used in circuit and electric equipment for over loading and short circuit protection, normally needn’t frequently operate. It can break rated short circuit current more than 30 times.

Vacuum switching tubes for load switches only need to break load current, or rated working current. It is usually used with fuse breaker that can break short circuit current, can break load current 200 to 300 times.

Vacuum switching tubes for contactor need frequently operate under certain load current. It can operate 500,000 to 1,000,000 time or even more. It is usually used with fuse breaker too.

Vacuum switching tubes for special utilization is used in special condition, such as that can break high voltage DC current, can trigger spark or can break high frequency current.
Vacuum switching tubes can be sorted by its contact head structure, such as flat contact head, transverse magnetic field contact head, axial magnetic field contact head, crossed magnetic field contact head (cup-shaped contact head) and other special contact head structure.
