一、特點(diǎn)：
1．鐵芯選用國(guó)際系列標(biāo)準(zhǔn)鐵芯規(guī)格；
2．鐵芯由大型專業(yè)加工廠沖制。鐵芯材料、沖片質(zhì)量及貨源均有保障；
3．生產(chǎn)工裝能與國(guó)際接軌，適合批量生產(chǎn)；
4．結(jié)構(gòu)變化多樣化，產(chǎn)品售價(jià)低廉。
二、型號(hào)命名辦法：
三、規(guī)格：
四、結(jié)構(gòu)：
本公司生產(chǎn)的經(jīng)濟(jì)系列EI型變壓器從結(jié)構(gòu)上分有抽屜式骨架框夾式安裝、工字式骨架框夾式安裝和工字式骨架彎腳式安裝三種類型，若安裝尺寸、安裝方式或外形尺寸不能滿足用戶要求時(shí)，可按用戶要求定制。
