Resistance to corrosion of components
Square tubes, coupling brackets, coupling bolts, screws, and locking wash-
ers are corrosion-resistant. We therefore recommend not applying the same
external coating to these parts as to the transformer tank.
Cutting square tubes, telescopic protective tubes, and protective cover
The square tubes, telescopic protective tubes, and protective cover are sup-
plied in overlengths (graded standard lengths). You must cut these parts to
the required size before mounting on the transformer. In rare cases, you also
have to cut the inner tube of the telescopic protective tube to the desired
length. The maximum total drive shaft length of the drive - last column = 15
m.
