Gawo la bizinesi la Power Transmission and Distribution (T/D) limapanga makina olumikizirana olimba komanso osagwira kutentha kwambiri. Makasitomala athu amagwiritsa ntchito makinawa kuwongolera ma voltages ofikira 1 200 kilovolts ndi mafunde ofikira 50 kiloamp. Arcing imapanga kutentha kwa 20 000 ° C. Kumene zitsulo wamba zingalephereke, tungsten-copper (WCu), copper-chromium (CuCr) ndi tungsten carbide-silver (WCAg) amasunga mutu wozizira.

Kusinthana kopangidwa ndi tungsten-mkuwa kumadalira kusokoneza ndi kulumikiza dera lamagetsi ngakhale pamagetsi apamwamba.

Zosawonongeka: Ndi kukana kwawo kovala kwambiri komanso kukokoloka kwa arc, omwe timalumikizana nawo amatha kugwira ntchito zaka zopitilira 40.

Okonzeka kuyika: Zolumikizana zokha sizokwanira - timasonkhanitsa ndikulumikiza magawo onse ofunikira a cholumikizira chosunthika komanso chokhazikika ndikukupatsirani makina olumikizirana okonzeka kukhazikitsidwa.
