Iphepha elinamachashazi edayimane liyi-insulating material eyenziwe ngekhebula lephepha njenge-substrate kanye ne-epoxy resin ekhethekile eguquliwe enamathiselwe ephepheni lekhebula elisesimweni samachashazi wedayimane.Ikhoyili inekhono elihle kakhulu lokumelana nengcindezi ye-axial short-circuit;ukuthuthukisa ukumelana komthelela okungapheli wekhoyili ngokumelene nokushisa namandla kunenzuzo empilweni nokuthembeka kwe-transformer.
