High performance ISO9001 Approved Amorphous Alloy Power Transformer and Distribution housing
1.Classification of housing protection grade is determined according to GB4280.
2.Normally dry type transformer is not equipped with housing protection, i.e. IP00. But we will mount housing of IP20 and IP23 under customer's requirement.
3.IP20 housing can prevent substance whose diameter is longer than 12mm coming to it, works as safety shield for the live part. There are punched holes on the top and bottom of housing for air circulation.
4.IP23 housing can prevent water that is 60° to the vertical line dropping into it, this kind of housing has ventilation shutter on its front and back wall plate (when applies IP23 housing, cooling ability of transformer will fall, and its capacity will fall for 5%).
5.Housing material has steel plate, aluminum alloy and stainless steel. If the housing is made of steel plate, it will be coated with the color that customer required.
6.There are doors on front and back wall plates, it is very convenient for users to maintain. And a hole is prepared at cable entrance, used to inlet cable.
