High Voltage 11/√3kv Capacitor Shunt Type With Capacity 334kVar
1.Overview of High Voltage 11/√3KV Capacitor Bank Shunt 334kVar Capacitor
High-voltage capacitors are mainly composed of lead-out porcelain bushings, capacitive element groups and shells. The shell is sealed and welded by thin steel plates, and the outlet porcelain sleeve is welded on the shell. The wiring terminal is led out from the outlet porcelain bushing. The capacitor element group (also called the core) in the shell is formed by connecting several capacitor elements. The capacitive element is made of capacitor paper, film-paper composite or pure film as the working medium, and aluminum platinum as the pole plate.
