Quneng Cast resin dry type transformer
Dry transformers: rely on air convection for cooling, generally used for local lighting, electronic lines. Mechanical equipment and other transformers, in the power system, the general turbine transformer, boiler transformer, ash transformer, dust transformer, desulfurization transformer, etc. are dry transformers, the ratio of 6000V/400V and 10KV/400V, for the rated voltage 380V load. Simply put, a dry-type transformer is a transformer whose iron core and winding are not impregnated in insulating oil.
