Iswishi yokuvula umthwalo enezikhundla ezimbili ecwiliswe uwoyela engu-35kV
1. Indawo yokucisha i-arc iyi-insulation uwoyela.
2. Isakhiwo esilula, ukusebenza okuthembekile
3.Isebenza ezinhlelweni zokusatshalaliswa kwamandla kagesi aphakathi naphansi
4. Ivame ukusetshenziswa kanye nama-fuse ane-voltage ephezulu
5. Kunezindlela ezahlukene zokusebenza.
