O le fa'amautu sa'o ulu insulator ma lelei lelei ma tau maualalo ma mautu tulaga lelei e liliu i taimi uma e tagata faatau

O le faʻamalolo saʻo ulu insulator na gaosia e Johnson o loʻo i ai tulaga lelei faʻapitoa i le fanua atoa o Saina.O le tulaga lelei o oloa e matua mautu, o faʻamaufaʻailoga e atoatoa ma faigofie ona faʻafetaui le tulaga IEC, ma mafai ona pasi le suʻega.E le mafaitaulia ona tuʻuina atu ma e leʻi iai lava ni faʻafitauli lelei.E ala i le faʻatau fou ma faʻapipiʻi atoatoa o meafaigaluega suʻega, o le au faʻapitoa e faʻamautinoa o oloa e sili atu nai lo manaʻoga o tagata faʻatau, ma faʻaauau pea ona faʻaopoopo e tagata faʻatau.E ui lava o le gaosiga o loʻo faʻatonutonuina ma o le tulaga lelei o oloa e mautu ma maualuga, o le tau e le taugata.Ona o le tele o le poto masani, o lenei oloa e maualuga lona lelei ma le tau maualalo, taugofie ma taugofie.
