Product use 

This product performance is low dissipation, good energy saving effect and economic operation, free maintenance. In addition to the process of advanced structure, short circuit, high level of lightning shock resistance, also has a resistance, moisture, dust, low noise characteristics, can be further load center. Being widely used in high-rise buildings, airport, station, wharf, power plants, substations, etc. Especially suitable for installing on the places where inflammable and explosive fire prevention requirement high. 
The standard transformer is without a shell, protection grade for IP00, if customer needs to provide for IP20 protection grade and IP23 shell. Shell can be selected according to the customer request of ordinary steel plate, stainless steel plate, aluminum alloy, such as materials, and pickling, phosphate, coating and other processing. The temperature control display, load recording meter installed in the low voltage side of shell, easy observation, safe and reliable.
