LW8-40.5 Series Sulfur Hexafluoride Circuit Breakers are threephase AC 50Hz outdoor high voltage electricalequipment,
applicable to 40.5 kV transmission and distribution system controlling and protection, alsofor contacting circuit breaker and
open-close capacitor bank. Product breaking performance is excellent, using compressed air interrupter, long electrical life,
at rated voltage 40 kV short-circuit current continuous on-off up to 21 times without maintenance; Two current transformers
per unit, for users choosing. The product adopts a new MKZ SF6 pointer density meter, pressure gauge readings are not
affected by temperature changes, easy to use. CT14 spring mechanism is used in this product. The circuit breaker contains floor
tank type and porcelain column type. Porcelain column type has two kinds of arrangement,parallel arrangement and elevated
T frame (middle type) arrangement.
