With the advanced technology brought in from overseas, we developed SC9, SCB9 series and SC10, SCB10seriespadding thin-insulation dry-type distributing transformer whose winding is sealed up with epoxy. therefore theresin insulatinodry-type transformer is flame-re tardant, explosion-proof, free from maintenance and pollution, and it is compacted and cango deep into load center. Besides, with scientific and reasonable design and coating craftworkit has advantages of lowpartial discharge capacity, low noise, good heat dispersion and it can run over a long time with140% rated load in thecircumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault orthe temperature is exceeded and switch off as well as the function of “black box”. It can be monitored and controlled byconnecting it to the computer through its Rs485 serial interface. Therefore, it is widely used in the places such as hotel, restaurant, airport, power plant, hospital, skyscraper, shoppingcenter, and residential areas and other adverse environments like subways, smelt and power plant, ship, ofshore drllingplatform,etc.
