8.5 Assembling the circuit-breaker pole
1. Suspend the breaking unit in the lifting sling and pull out the puffer so that the
pull-rod (1) is accessible for assembly.
2. Carefully clean the sealing surface for the sealing ring on the post insulator (2).
Also clean the lower flange (3) and lubricate well using grease ”G” so that the
sealing ring is held in place during assembly. Place the sealing ring in its
groove.
3. Slowly lower the breaking unit so that it comes in position to fit the pin,
approx. 75-100 mm above the post insulator.
4. Connect the puffer’s pull-rod
(1) to the operating insulator
using pin (4), washer (5) and
circlip (6).
