Tiav daws qhov kev raug mob ntawm tus kheej thiab kev tuag tshwm sim los ntawm qhov tsis zoo ntawm cov txee thiab cov khoom sib tshooj ntawm cov khoom txawv teb chaws;
Cov kev siv dav dav tus nqi yog tsawg, thiab kev nqis peev ib zaug siv tau ntau dua 20 xyoo (kev zam ntawm lub thawv hloov cov thawv ua haujlwm thiab cov nqi siv ntxiv);
Qhov tshwj xeeb tsim ntawm lub txee tuaj yeem tiv thaiv kev cuam tshuam ntawm sab nraud;
Tus nqi rov ua dua tshiab ntawm cov khoom siv lub thawv yog qhov siab, uas tuaj yeem tiv thaiv lub cev kom tsis txhob nyiag;
Txoj kev siv lub tshuab raj yuav txo cov kev saib xyuas tus nqi ntawm lub txee (koj tsuas tuaj yeem hloov kho cov khoom puas);
Kev sib tov nrog qhov kub thiab txias tsis tsim cov pa txaus.
Hauv ntej, qhov qis-voltage cable cable lub thawv ua los ntawm cov khoom siv fiber ntau polyester muaj ntau yam zoo xws li kev rwb thaiv tsev zoo, kev tiv thaiv corrosion, kev pab lub neej ntev, thiab kev txhim kho yooj yim.
