Compact SubStations vacuum poured Insulations ZW32-36 ARC
l ZW32 series high voltage out door circuit breaker can be used for 50HZ 40. 5kv outdoor high voltage electrical equipment.
l Attached spring operating structure and electromagnet operating structure can manipulate electric opening and closing in a distance, or accumulate energy for manual operation.
l The design performance strictly sticks to our national standard GB1984-89 for high voltage alternating current vacuum circuit breaker, and meet the requirements of International Electro technical Commission (IEC) IEC-56 for high voltage alternating current vacuum circuit breaker.
l Mainly used in controlling and protection of outdoor power transmission and transformation system of 35kv, also in normal operation and short-circuit protection for all kinds of power grid and frequent operation place.
l Highest system voltages Um related to the rated voltages are defined in IEC 60071-1.
l These series of VCBs are ceramic pillar type.
l Vacuum interrupter is installed in upper part of ceramic insulator.
l It has characteristics of well tightness and high temperature endurance, non-combustion and non-exploration, easy mounting, anti-aging and long service life.
