Description

12kV Outdoor Vacuum Circuit Breaker Stainless Steel Made 3 Poles Outdoor Powerful Vacuum Circuit Breaker Silver Color


Product Description:


ZW8-12 outdoor AC high voltage vacuum circuit breaker is mainly used to break and close load current, over-load current and short-circuit current in outdoor 12kV three-phase alternating current 50Hz power system, also suitable for occasion with frequent operations.The product suitable for substations, industrial and mining establishments, rural power network and occasions with frequent operation to protect and control.



Feature:


1 With anti-pollution ability, internal insulation for the air and epoxy resin composite insulation.
2 Equipped with a missile energy storage operating mechanism.
3 Can be equipped with one-side (left side) or two-side separation switch, external PT.


Advantages:


1.It is equipped with CT23 type spring energy-stored operating mechanism. Energy-stored, opening and closing can be achieved by motor or by manual.
2.ZW8-12G consists of ZW8-12 breaker and isolator, called combined breaker, can be used as sectionalizer.
3.The structure of breaker is of three-phase assembled in a tank, three-phase vacuum arc-extinguishing chamber enclosed in metal tank, insulation material between phases and phase to each made of SMC.
4.reliable performances, and high insulating strength.



Conditions:


1.Ambient temperature:-15°C~+40°C
2.Wind pressure:≤700Pa(equivalent to wind speed 34m/s)
3.Altitude:≤1000m
4.Seismic intensity:≤8
*The air filthy should be win in Ⅲ degree. Frequently violent vibration should be forbidden.
