20KV Grade SCB10 dry-type transformer winding is sealed up with epoxy, therefore the resininsulating dry-type transformer is flame-retardant, explosion-proof, free frommaintenance and pollution, and it is compacted and can go deep into loadcenter, besides, with scientific and reasonable design and coating craft work,it has advantages of low partial discharge capacity, low noise, good heatdispersion and it can run over a long time with 125% rated load in the circumstance of cold wind. It applies intelligent thermal controller and hasthe functions that it will alarm when there is fault or the temperature is exceededand switch off as the function of “black box”. It can be monitored andcontrolled by connecting it to the computer through its RS485 serial interface.
Therefore, it is widely used in the placessuch as hotel, restaurant, airport, power plant, hospital, skyscraper, shoppingcenter, and residential areas and other adverse environments like subways,smelt and power plant, ship, offshore drilling platform, etc.
