稳变SGB(DGB)系列三相(或单相)变压器主要型式为高低压线绕或饼绕，绕组材质为双丝包(漆包)线，选 用优质铁芯。采用整体浸漆的形式保证了良好的绝缘和机械强度，大大提高了变压器的使用寿命以及可靠性。
Wenbian The main type of SGB (DGB) series three-phase (or single-phase) transformers is high and low voltage wire wound or cake wound. The winding material is double wire (enameled) wire and high-quality iron core is selected. The overall dipping paint form ensures good insulation and mechanical strength, and greatly improves the service life and reliability of the transformer.
