Pepa insait long kebol, ol i save kolim olsem insulating pepa o kebol insulating pepa, i gat ol dispela bikpela wok:
1. Insulation fanksen: Praemeri wok blong insulation pepa hemi insulation. I save blokem karent blong ron i go bitim ol kondukta blong kebol, mekem sua se i gat sefti mo reliabiliti blong pawa transmisen. insulating pepa i gat hae insulation pefomens mo i save stanap strong long hae voltej..
2. Hae-tempereja resistens mo aging resistens: Insulating pepa i save stanap strong long wan spesel tempereja ranj, i blokem ol samting we i stap kam olfala from ol jenis long tempereja mo mentenem long-tem insulesen pefomens blong ol kebol.
3. Oil absorpsen na pulapim: Long sampela kain kebol, olsem ol kebol i gat oil i stap insait long en, pepa insulesen i gat tu wanpela oil absorpsen wok, inap long kisim na lukautim sampela mak bilong insulesen .
Insulating oil i no givim moa insulation tasol, tasol em i helpim tu long mekim kebol.
4. Mekanikal sapot: Insulating pepa i givim tu sampela mekanik sapot long lukautim ol kebol kondukta long ol ekstenel fisikel bagarap.
