1. Siv cov peev txheej ntawm thawj tus tsiaj ntawv ntawm Suav lub cim pinyin los qhia qhov rwb thaiv tsev hom, khoom siv tus neeg xyuas pib, sab hauv sheath cov khoom thiab cov qauv yam ntxwv. Piv txwv li, Z sawv rau ntawv (zhi); L sawv rau txhuas (lv); Q sawv ua hmoov txhuas (qian); F sawv rau theem sib cais (fen); ZR sawv kev nplaim taws npliag (zuran); NH sawv rau hluav taws ua hauj (naihuo).
2. Siv cov lej los qhia qhov muaj pes tsawg leeg ntawm txheej tiv thaiv sab nraud, nrog ob tus lej. Tsis muaj lej txhais tau tias tsis muaj cov ris tsho ua rog thiab tsis muaj txheej txheej sab nrauv. Thawj tus lej qhia tias muaj cuab kav, thiab tus lej thib ob qhia txog sab nrauv. Piv txwv li, sab caj npab sab nraud ntawm tuab cov hlau tsis muaj hlau yog qhia raws li 41.
3. Lub thawv qauv qauv yog feem ntau nyob rau hauv kab raws li qhov kev teeb tsa ntawm cov qauv cable: insulating khoom siv; cov khoom neeg xyuas pib; kev tiv thaiv sab hauv txheej; txheej tiv thaiv txheej.
4. Cov khoom siv cable tau qhia los ntawm tus qauv, ntsuas cov ntsuas thiab qhov ntsuas tshwj xeeb. Cov txheej txheem yog qhia kom meej rau cov ntsuas hluav taws xob, ntau ntawm cov xoos thiab cov chaw sau npe hauv cheeb tsam tom qab tus qauv lej.
