Inkcazo:

Ikhondaktha nganye yomgama omde kunye nomthamo omkhulu weentambo zothumelo lwamandla ombane aphezulu zamkelwe ezimbini, ezine & ngakumbi iingcingo ezicandekileyo.Ukuza kuthi ga ngoku iintambo zothumelo ze-220KV & 330KV zixhotyiswe ngeengcingo ezimbini ezicandiweyo ngelixa iintambo zothumelo ze-500KV zixhotyiswe ngeengcingo ezintathu okanye ezine ezicandiweyo;ezo migca yamandla ombane aphezulu kakhulu okanye i-ultrahigh yamandla ombane aphezulu kuno-500KV idityaniswa neengcingo ezintandathu nezisibhozo ezicazululiweyo.

Ukugcina umgama phakathi kweentambo zombane zombane ongaguquguqukiyo wokubonelela ukusebenza kombane okusekiweyo kunye nokunciphisa i-voltage gradient ibonakala kumphezulu ukuze iintambo zingavusi amandla ombane okhokelela kunxibelelwano kwisekethe emfutshane, kufuneka i-spacer ifakwe. kwisithuba phakathi kwezithuba ezahlukeneyo.Ngaphaya koko ufakelo lwe-spacer luya kuba luncedo ukususa i-swing kwi-span kunye ne-aero vibration.
