Product Details
Overview
1.1 Product model and name
LW33-126/T3150-40 high-voltage sulfur hexafluoride AC circuit breaker.
1.2 Main uses and scope of application
LW33-126/T3150-40 high-voltage sulfur hexafluoride AC circuit breaker is suitable for AC 50Hz, 110kV power systems. Trede high-voltage electrical appliances are control and protection equipment for power systems and can also be used as contact circuit breakers.
1.3 Relevant standards and main features
The circuit breaker complies with the requirements of GB1984-2003 "AC high-voltage circuit breakers" and IEC 6227 1-100 "High-voltage AC circuit breakers". The circuit breaker uses SF6 gas as insulation and arc extinguishing medium, adopts the self-energy arc extinguishing principle, and is equipped with a CT-30 spring operating mechanism. It has the characteristics of strong breaking capacity, low operating work, and high reliability.
