S series roj-immersed transformers feem ntau suav nrog cov qauv S9, S11, S13, S18, S20, thiab S22. Cov yam ntxwv tseem ceeb thiab cov xwm txheej siv tau ntawm cov qauv no yog raws li hauv qab no:
1. S9 thiab S10: Cov no tsis yog -cov roj nyob hauv- cov tshuab hloov pauv, dav siv hauv kev lag luam thiab mining lag luam, kev ua liaj ua teb, thiab kev tsim vaj tsev.
2. S11: Siv high-zoo, siab-permeability txias-rolled silicon steel los xij, los ntawm cov longitudinal thiab transverse shearing thiab tsis siv neeg lamination tshuab, nws zoo txo qhov tsis muaj -load poob thiab tsis muaj-load tam sim no, featuring tsawg poob, tsis muaj suab nrov.
3. S13: Tsis tas li siv high-zoo, siab-permeability txias-cov ntaub ntawv silicon steel, los ntawm cov txheej txheem lamination thiab kev vibration damping ntsuas, nws ntxiv txo cov suab nrov thiab xyuas kom tsis muaj qhov to thiab muaj zog luv luv - Circuit Court withstand peev.
