The structure and performance of core and winding in SC9 series resin cast dry-typetransformer is introduced. Its ability of withstanding impulse and short circuit is analysed emphatically.
The zero sequence current transformer is full enclosed type. The secondary windings and iron core are insulated by epoxy resin. The middle hole is used for cable going through.
本型零序电流互感器为全封闭式。二次绕组及铁芯均浇注在聚脂树脂内。中间窗孔供三相电缆穿过。

This type of transformer is fully enclosed structure, using annular iron core and the annealing treatment. The iron core, primary and secondary windings are casted with epoxy resin.
