Tus naj npawb ntawm cov tsis muaj zog nyob rau ntawm qhov kis tau tus mob no ntau dua 60, thiab nws qhov voltage tau pom tseeb yog 1000 kv.
Zoo li qhov no, 750 kv xa kab muaj ntau dua li ntawm 35 daim ntawm insulator.
Nov yog 500 kv kis kab nrog ze li ntawm 30 insulator daim hlau.
Thiab tus naj npawb ntawm cov insulators rau 330 kV kis kab yog li 20.
Txog rau 220 kv kis kab, tus naj npawb ntawm insulator daim hlau yog 12-14.
Rau rau 110 kV kis kab, tus naj npawb ntawm cov kab hluav taws xob yog kwv yees li 7-9.
Yog tias nyob rau ntawm qhov chaw siab, thaj chaw muaj kuab paug ntau, cov neeg ntawm cov rwb thaiv tsev yuav nce.
