General Introduction
CL-40.5 type bevel gear mechanism is used for manual control operation with
JN22-40.5/31.5 indoor HV earthing switch. It comply with KYN□-40.5 switchgear
cabinet and other various types switchgear.
Operating shaft's rotation angle is 270°: 90°(open-close)
The operation mechanism as the drawing shows is right operation, the closing
centerline is the rotation line of operation mechanism. If need left operation,
please ask the factory to change the direction, and user can install the bevel gear
symmetrically on the left side according to the drawing above.
As the opening centerline is rotation line of operating mechanism, user can
install the main shaft of earthing switch right operation or left operation.
Installation according to the drawing shows above is left operation, symmetrically
is right operation.
