5kVA-1000kVA Solar isolation transformers

Product Overview：

The transformer is the main component of various power supplies and electrical equipment, the transformer is composed of cylindrical windings and laminated iron cores, and the iron cores are stacked with new high-quality high-silicon silicon steel sheets and fully mitered joints. The company adopts advanced production technology, with imported Spanish winding machine and a full set of vacuum pressure impregnation equipment; The winding adopts the whole column winding method; Vacuum impregnation of the transformer to make the insulation grade of the transformer reach class F or H. The output and input voltages of the transformer can be designed according to customer needs.
