ZW38-40.5 series overhead ceramic insulator high voltage outdoor circuit breaker

ZW38-40.5 series overhead ceramic insulator high voltage outdoor circuit breakerZW38-40.5 series overhead ceramic insulator high voltage outdoor circuit breaker is a type of50HZ three-phase alternating current high voltage switch equipment. It ‘s mainly used in normaloperation and short-circuit protection for all kinds of power grid. Attached type CT19-IVB springoperating structure and electromagnet operating structure can manipulate electric opening andclosing in a distance, or accumulate energy for manual operation.Vacuum interrupter is put in the insulator fulfilled with SF6 to protect it from effect ofouter circumstances, thus anti-contamination, anti-condensation, and reliable. Each VCB canequip with 6-12pieces of current transformer according to customer’s requirement.The design performance strictly sticks to our national standard GB1984 - 89 for high voltagealternating current vacuum circuit breaker, and meet the requirements of International Electrotechnical Commission (IEC) IEC-56 for high voltage alternating current vacuum circuit breaker.
