CTM1 spring operating mechanism is used in zf-126 series zf1-252 disconnector, grounding switch load switch with equivalent torque.
The mechanism uses the principle of spring symmetry passing through, through the positive negative rotation function of the motor, the mechanism can compress the spring to realize fast opening closing. The mechanism has both manual electric operation functions.
