O pine insulators o ituaiga tuai ia o insulators i laina eletise eletise ma laina tufatufaina.Ona o lona gaosiga faigofie, taugofie, faʻapipiʻi faigofie ma e mafai ona faʻaititia le maualuga o le olo (ona o le insulator o loʻo faʻapipiʻi saʻo, o le vaega faʻavae o loʻo i lalo), o loʻo faʻaaogaina lautele i le tolu-vaega eletise eletise nominal voltage 6 ~ 35kV. , taimi e le sili atu i le 100Hz, laina eletise maualuga i luga ole laiga i nofoaga eleelea, mo le faʻapipiʻiina ma le uaea lagolago.
