Iyo Power Transmission uye Distribution (T / D) bhizinesi unit inovandudza yakasimba uye yakanyanya kupisa-inodzivirira switch yekubatanidza masisitimu.Vatengi vedu vanoshandisa masisitimu aya kudzora mavolts anosvika 1 200 kilovolts uye mafungu anosvika makumi mashanu kiloamps.Arcing inogadzira tembiricha inosvika 20 000 °C.Apo simbi dzakajairwa dzaizokundikana, tungsten-mhangura (WCu), mhangura-chromium (CuCr) uye tungsten carbide-silver (WCAg) inochengeta musoro unotonhorera.

Kushandura mabikirwo akaitwa tungsten-mhangura anovimbwa nawo kuti avhiringidze uye abatanidze dunhu remagetsi kunyangwe pakakwirira voltages.

Isingaparadzike: Nekupokana kwavo kwakakwira uye nekunaka kwearc erosion zvivakwa, ma arcing anobatika anogona kusvika hupenyu hwesevhisi hweanopfuura makore makumi mana.

Yakagadzirira kuisirwa: Mabatiro ega haana kukwana - isu tinounganidza uye tinobatanidza ese anodiwa ega ega ega ega ega ekufambisa uye yakagadziriswa switch yekubata uye kukupa iwe yakakwana yekubata system yakagadzirira kuisirwa.
