结构简介Construction

本型电流互感器为全封闭式支柱式结构，耐污染及潮湿。本产晶有两种不同的结构尺寸。LZZB9-35是LCZ-35替代晶。

This current transformer is fully enclosed and posts type. It has a good ability of antipollution and moisture-proof especially being used in damp tropics and highland. This product has two different striations and size. It is a new product for superseding the current trans former of the type LCZ-35.
