穩(wěn)變SGB(DGB)系列三相(或單相)變壓器主要型式為高低壓線繞或餅繞，繞組材質(zhì)為雙絲包(漆包)線，選 用優(yōu)質(zhì)鐵芯。采用整體浸漆的形式保證了良好的絕緣和機(jī)械強(qiáng)度，大大提高了變壓器的使用壽命以及可靠性。

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.
