Overhead Ceramic Insulator High Voltage Outdoor Circuit Breaker

ZW38-40.5 series overhead ceramic insulator high voltage outdoor circuit breaker is a type of 50HZ three-phase alternating current high voltage switch equipment. It a s mainly used in normal operation and short-circuit protection for all kinds of power grid. Attached type CT19-IVB spring operating structure and electromagnet operating structure can manipulate electric opening and closing in a distance, or accumulate energy for manual operation.

Vacuum interrupter is put in the insulator fulfilled with SF6 to protect it from effect of outer circumstances, thus anti-contamination, anti-condensation, and reliable. Each VCB can equip with 6-12pieces of current transformer according to customera s requirement.

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. It has characteristics of simple structure, small size and easy mounting.
