Power electric steel plant low voltage 1140v VC

l  CKJ5-250 1140V 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.
