Expert Tip #16: Rectifier Cabinet Material & Finish

Rectifier Cabinet Materials:
Steel is most often used for air-cooled rectifier cabinets due to its relative durability and cost. Aluminum and stainless steel are also available but at a greater cost. Oil-cooled cabinets are almost always (if not always) heavy-gauge steel for durability purposes.

Cabinet Finish
Many standard, air-cooled, steel CP rectifier cabinets utilize a hot-dipped galvanized (zinc) finish, that is very durable, but not extremely attractive. There are more attractive paint or FBE powder coating options that allow for color variations, which may be a need in city settings.

Aluminum cabinets are available in raw aluminum (not recommended), painted or FBE powder coated, and/or anodized.

Stainless steel cabinets are typically provided in raw metal due to the protective nature of stainless.
