  • Information on 11kv dry type transformer loading from ANSI/EEE C57.96-1989 indicates that you can have a 20-yr life expectancy for the insulation system in a dry cast resin transformer. For dry electric transformer having a 220 (degrees) C, insulating system and a winding hot-spot temperature of 220 (degrees) C, and with no unusual operating conditions present, the 20 yr life expectancy is a reasonable time fame. However, due to degradation of the insulation, a cast resin transformer might fail before 20 years. Most 150 (degrees) C rise 11kv dry type transformer are build with 220 (degrees) C insulation systems. Operating such a dry cast resin transformer at rated kVA on a continuous basis with a 30 (degrees) C average ambient in dry electric transformer should equate to a "normal"dry cast resin transformer useful life.
    The life of a dry electric transformer increases appreciably if the operating temperature is lower than the maximum temperature rating of the dry electric transformer. However, you should recognize that the cast resin transformer life expectancy of cast resin transformer operating at varying temperatures is not accurately known. Fluctuating load conditions and changes in ambient temperature of dry electric transformer make it difficult, if not impossible, to arrive at such definitive information.
    11kv dry type transformer are available in three general classes of insulation. The main features of insulation are to provide dielectric strength and to be be able to withstand certain thermal limits. dry electric transformer insulation classes are 220(degrees) C (Class H). 185 (degrees) C (Class F), and 150 (degrees) C (Class B). Temperature rise ratings are based on full-load rise over ambient (usually 40 (degrees) C above ambient and are 150 (degrees) C (available only with Class H insulation), 115 (degrees) C (available with Class H and Class F insulation) and 80 (degrees) C (available with Class H, F, and B insulation). A 30 (degrees) C winding hot spot allowance is provided for each class of dry cast resin transformer.
