THREE PHASE POLE MOUNTED DISTRIBUTION TRANSFORMER
INSTRUCTION
MANUAL #105
MAINTENANCE
A periodic visual inspecon of the transformer is recommended. At
such mes, the general condion of the following should be noted:
1. High voltage bushings
2. Low voltage bushings
3. Arresters (if provided)
4. Evidence of oil leakage
5. Ground connecons
6. Accessories
7. Safety labels.
Where tanks show evidence of rusng or deterioraon of the finish,
they may be cleaned and then retouched with paint. It is necessary to
remove all loose paint and rust by wire brushing, scraping, or sanding,
and clean with a good solvent. Apply an acrylic lacquer, alkyd enamel,
two part urethane or silicone alkyd primer, allow to dry, and then
apply a color matched compable top coat and allow to dry.
If metal is rusted to the point of being weak such that the tank
integrity can be compromised, repair or replace the part rather than
painng it.
