Substation Dry Type Transformer Brochure

Current technology yields a dry type transformer that is fully equal to its mineral oil insulated counterpart. Dry types excel in several important aspects. They can be located indoors without the use of a fireproof vault or special catch basins, on roofs, near buildings, or anywhere within an industrial or commercial building. Industry standards have been developed to give users better yardsticks for specification and purchasing. The latest standard, set for the Underwriters Laboratories (UL), encompasses those developed by IEEE, NEMA, ANSI, and various other agencies.
