2. Product Features
The overload capacity of dry-type transformer is influenced by environmental temperature, overload conditions (origin load), the insulation of the transformer cooling and heating time constant, etc., and among which the environment temperature has greatest impact on dry-type transformer overload performance. High environment temperature cripples the overload capacity of transformer, vandalizes insulation, and also influences the safe operation of dry-type transformer and service life. Thus, suitable cooling method to reduce the environmental temperature is critical for the operation of dry type transformer, and temperature control system is designed to tackle the problem.
Pearl electric Co., ltd. has developed low flux density and load loss design, reasonable arrangement of the coil airway for lower temperature rise.
Imported Peter Huntsman H-class resin system has been adopted, and insulation system passed heat resistance test.
