Spring Mechanism CT35

Main purpose and scope of use

The CT35 spring operating mechanism can be used to operate 35KV SF6, vacuum circuit breakers and other types of high voltage circuit breakers with equivalent closing power. Its performance meets the requirements of GB1984-89 "AC High Voltage Circuit Breaker" and "Technical Conditions" of this product Claim.

The mechanism's mechanical closing spring energy storage methods include electric energy storage and manual energy storage; the opening operation has three types: opening electromagnet, overcurrent trip electromagnet and manual knob operation; closing operation has closing electromagnet And manual knob operation two kinds.
