8. Assembling the circuit-breaker pole

To re-assemble the breaking unit follow the dismantling instructions in the reverse
order,

see Chapter 5

.

N. B.

When re-assembling, all sealing rings must be new. Careful cleaning and
treatment of sealing surfaces is required.

8.1 Treatment of contact surfaces

Before re-assembling the breaking unit, treat the contact surfaces as follows:

8.1.1 Fixed contact surfaces

•

Silver-plated:
If necessary, clean silver-plated contact surfaces, using a soft cloth and solvent
(alcohol).

N. B.

Polishing using Scotch Brite or grinding must not take place.

•

Copper surfaces:
Copper surfaces must be clean and free from oxide. If necessary, clean with a
cloth, and solvent (alcohol), or with Scotch Brite.

N. B.

After cleaning with Scotch Brite, always remove all loose particles from
the surfaces using alcohol.

•

Aluminium surfaces:
Brush clean contact surfaces of aluminium, using Scotch Brite. Immediately
thereafter carefully clean the surfaces to remove any loose particles with a dry,
clean cloth. Then coat the surfaces with a thin layer of Vaseline, grease “P”
(ABB art. No. 1171 5011-102).

N. B.

Grease should be applied within five minutes of cleaning and the joint
must be fitted within 15 minutes.

8.1.2 Movable contact surfaces

•

Silver-plated:
If necessary, clean silver-plated movable contact surfaces, using a soft cloth
and solvent (alcohol).

•

Non-silver-plated:
Clean moving contact surfaces that are not silver-plated in a similar way to
silver-plated surfaces. However, they may also be cleaned with Scotch Brite.
After cleaning with Scotch Brite, always be remove all loose particles.

•

Greasing:
Apply Grease “N” (ABB art. No. 1171 4016-607) in a covering, but very thin
layer to the male contacts and the puffer cylinder surfaces. Carefully wipe off
all excess grease.
