Lub tswv yim ntawm kis tau tus yees, kis tau tus mob conductors tau txais kev txhawb nqa los ntawm ntu ntawm cov kav hlau txais xov. Cov kab hluav taws xob siab siv "hlau yees," thaum cov kab hluav taws xob tsawg, xws li cov pom hauv thaj chaw nyob, siv "cov ncej ntoo" lossis "cov ncej ntoo." Ua ke, lawv raug hu ua "towers." Cov kab hluav taws xob siab xav tau qhov kev nyab xeeb loj dua, yog li lawv yuav tsum tau txhim tsa ntawm qhov siab dua. Tsuas yog cov tuam tsev hlau muaj peev xwm txhawb nqa kaum tawm tons ntawm kab. Ib tus ncej tsis tuaj yeem txhawb nqa qhov siab lossis qhov hnyav, yog li cov ncej feem ntau siv rau qib qis dua.

Feem ntau muaj ob txoj hauv kev los txiav txim siab qhov voltage:

1.Pole tooj phaj paub txoj kev

Ntawm cov yees ntawm high-voltage kab, ncej tooj daim hlau feem ntau yog ntsia, qhia meej txog qhov sib txawv voltage xws li 10kV, 20kV, 35kV, 110kV, 220kV, thiab 500kV. Txawm li cas los xij, vim muaj cua thiab hnub ntev los yog ib puag ncig ib puag ncig, cov ntawv xov tooj ntawm tes yuav tsis meej lossis nyuaj nrhiav, yuav tsum tau saib xyuas kom nyeem kom meej.

2.Insulator hlua paub txoj kev

Los ntawm kev soj ntsuam tus naj npawb ntawm cov hlua hluav taws xob, qhov ntsuas hluav taws xob tuaj yeem txiav txim siab kwv yees.

(1) 10kV thiab 20kV kab feem ntau siv 2-3 cov hlua insulator.

(2) 35kV kab siv 3-4 cov hlua insulator.

(3) Rau 110kV kab, 7-8 cov hlua insulator siv.

(4) Rau 220kV kab, tus naj npawb ntawm cov hlua insulator nce mus rau 13-14.

(5) Rau qhov siab tshaj plaws voltage ntawm 500kV, tus naj npawb ntawm cov hlua insulator yog siab li 28-29.
