10.5kv dry distribution transformers
1. General introduction of dry type transformer
With the advanced technology brought in from overseas, we developed SC9,SCB9 series and SC10,SCB10 series padding thin-insulation dry type transformer whose winding is sealed up with epoxy, therefore the resin insulating dry-type transformer is flame-retardant, explosion-proof, free from maintenance and pollution, and dry type transformer is compacted and can go deep into load center, besides, with scientific and reasonable design and coating craft work, dry type transformer has advantages of low partial discharge capacity, low noise, good heat dispersion and it can run over a long time with 125% rated load in the circumstance of cold wind. It applies intelligent thermal controller and has the functions that it will alarm when there is fault or the temperature is exceeded and switch off as the function of “black box”. dry type transformer can be monitored and controlled by connecting 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, shopping center, and residential areas and other adverse environments like subways, smelt and power plant, ship, offshore drilling platform, etc.
