Transformers & Apparatus

This is a picture of a transformer that R&H flowcoated and painted in the Midwest with Indurasil Gloss Enamel from Induron Coatings.

Maintenance Doesn’t Cost; It pays!

The coatings industry in general, exists on a very simple premise. It is cheaper to maintain your equipment than it is to buy new. This is especially true in the transformer market. Considering the fact that most transformers are shipped from overseas, it is quite possible that painting an existing transformer, may be less than just the freight cost for a new transformer. Not to mention paying for the unit itself.

Take the time to get on a ladder and inspect up high. The top of the transformer is usually at least 5 years ahead of the sides in the wear cycle.

Transformers are an integral part of any Transmission & Distribution network, and typically the most expensive single component of any substation. It only makes sense that you would want to make sure you maintain the integrity of the tanks and radiators. That way you can lessen any chance of internal contamination, and keep the cooling and voltage ratings within the specs. How many times have you seen with a transformer with an oil leak? Generally speaking, oil can’t come out without something going in to take its place. That something is more than likely either air or water, neither of which you want inside your transformer, because they both aid in the development of corrosion.

Most people think of paint as just a decoration, or a way to spruce up their living room or kitchen. That’s just simply not the case in industrial environments. Maintaining surface protection and not allowing rust to start in the first place, is a good way to minimize the chance of leaks developing; as well as maintain the value of your capital if you ever decide to sell it. Two full coats of paint, flow coated on the radiators for complete coverage, is essential to keeping radiators healthy. Letting it go though, can easily end up causing severe corrosion and leakage, which have the capability of ending in equipment failure, fire, and power outages. Don’t get caught in the vicious cycle of reactive maintenance when it can be prevented, and quite easily. It’s about as predictable as the rising of the sun, which has been pretty doggone regular for awhile now.


In addition to large substation transformers, we’ve also had great success with:

  • Oil tank breakers
  • Pad mount transformers
  • Fiberglass cabinets
  • Light poles
