Ntauwd yog feem ntau faib los ntawm cov duab ua tsib hom: goblet-zoo li tus, miv- taub hau-shaped, (shàng)-puab, (gān)-puab, thiab chim{5}}puab. Lawv kuj raug cais los ntawm lub hom phiaj mus rau hauv cov tuam tsev nro, ncaj- kab yees, lub kaum ntse ntse, cov tsev hloov pauv (ntauwd rau kev hloov pauv tus neeg xyuas pib txoj haujlwm), lub davhlau ya nyob twg, thiab cov neeg hla kev.
Raws li lawv txoj haujlwm hauv cov kab sib kis, cov yees tuaj yeem muab faib ua ncaj nraim - kab yees, nro cov yees, lub kaum sab xis, cov yees hloov, hla cov yees, thiab cov pej thuam davhlau ya nyob twg. Ncaj- kab yees thiab nro yees yog tsim rau ntawm cov kab ncaj nraim; lub kaum sab xis yog txhim tsa ntawm khoov hauv cov kab sib kis; siab hla ntauwd yog tsim rau ntawm ob sab ntawm cov khoom raug hla; transposition towers yog ntsia rau ntawm ib ntus kom sib npaug ntawm qhov impedance ntawm peb tus neeg xyuas pib; thiab lub davhlau ya nyob twg yees tau txhim tsa qhov twg cov kab sib txuas txuas mus rau cov qauv substation.
Raws li cov txheej txheem siv cov khoom siv, cov yees siv hauv cov kab sib kis feem ntau suav nrog cov pob zeb ua kom muaj zog thiab cov yeeb yaj kiab hlau. Los ntawm qhov kev xav ntawm kev tswj xyuas tag nrho cov qauv kev ruaj ntseg, lawv tau muab faib ua tus kheej - txhawb nqa cov pej thuam thiab cov tub yees. Muaj ntau yam qauv qauv ntawm lub zog xa hluav taws xob yees. Saib ntawm cov kab sib txuas uas twb tau tsim hauv kuv lub tebchaws, hlau yees yog feem ntau siv rau cov qib voltage ntau dua 110kV, thaum cov pob zeb muaj zog yog feem ntau siv rau qib voltage tsawg dua 66kV. Ntauwd txiv leej tub xov hlau yog siv los sib npaug ntawm cov load sab nraud thiab tus neeg xyuas pib nro ntawm tus pej thuam, txo cov sijhawm khoov ntawm tus pej thuam. Kev siv cov txiv neej cov xov hlau txo cov khoom siv ntauwd thiab txo tus nqi ntawm cov kab. Guyed towers feem ntau yog siv rau txoj hauv kev hauv tiaj tiaj. Kev xaiv ntauwd hom thiab cov duab yuav tsum tau ua raws li kev suav kom paub tseeb tias cov khoom siv hluav taws xob tau ntsib thaum tseem xav txog qib voltage, tus naj npawb ntawm circuits, struts, thiab geological tej yam kev mob ntawm cov kab sib kis. Hom pej thuam tsim nyog rau ib txoj haujlwm tshwj xeeb yuav tsum raug xaiv raws li kev xav tau, thiab los ntawm kev sib piv ntawm kev lag luam thiab kev ua haujlwm, yuav tsum xaiv cov cuab yeej thev naus laus zis thiab kev lag luam tsim nyog ntauwd.
