Fikradda munaaradaha gudbinta, kaariyaasha gudbinta waxaa taageeraya qaybo ka mid ah munaaradaha gudbinta. Xadhkaha korantada sare waxay isticmaalaan " munaaradaha birta ah ", halka xadhkaha korantada hooseeya, sida kuwa lagu arko meelaha la deggan yahay, ay isticmaalaan "tirarka alwaax" ama "tirarka la taaban karo." Si wada jir ah, waxaa loogu yeeraa " munaaradaha." Xadhkaha korantada ee sarreeya waxay u baahan yihiin masaafo badbaado oo weyn, sidaas darteed waxay u baahan yihiin in lagu qotomo dherer weyn. Keliya munaaradaha birta ayaa awood u leh inay taageeraan tobanaan tan oo xariiqyo ah. Tiir keliya ma taageeri karo dhererka ama miisaankan oo kale, sidaas darteed tiirarka guud ahaan waxaa loo isticmaalaa heerarka tamarta hoose.

Guud ahaan waxaa jira laba hab oo lagu go'aaminayo heerka danab:

Habka aqoonsiga saxanka lambarka 1.Pole

Taawarrada xadhkaha korantada sare, ayaa inta badan lagu rakibaa taarikada nambarada tiirarka, kuwaas oo si cad u muujinaya heerarka korantada ee kala duwan sida 10kV, 20kV, 35kV, 110kV, 220kV, iyo 500kV. Si kastaba ha ahaatee, soo-gaadhista muddada-dheer ee dabaysha iyo qorraxda ama arrimaha deegaanka awgeed, taarikada lambarrada tiirka ayaa laga yaabaa inay caddaato ama ay adkaato in la helo, waxay u baahan tahay indho-indheyn dhow si loo akhriyo si cad.

2. Habka aqoonsiga xadhigga insulator

Marka la fiiriyo tirada xargaha dahaarka, heerka korantada ayaa qiyaas ahaan la go'aamin karaa.

(1) 10kV iyo 20kV inta badan waxay isticmaalaan 2-3 xadhkaha insulators.

(2) 35kV khadadka waxay isticmaalaan 3-4 xadhkaha insulator.

(3) Xadadka 110kV, 7-8 xadhkaha insulator ayaa la isticmaalaa.

(4) Xadadka 220kV, tirada xadhkaha insulator-ku waxay kordhisaa 13-14.

(5) Heerka korantada ugu sarreeya ee 500kV, tirada xadhkaha insulator-ku waxay u badan tahay 28-29.
