I-silicone yerabha ye-fiberglass ye-tubing luhlobo lwetyhubhu ephothiweyo nge-fiberglass engeyiyo-alkali kwaye igqunywe ngohlobo olukhethekileyo lwe-silicone resin nangona ubushushu obuphezulu. Olu hlobo Icala langaphakathi yi-fiberglass kwaye yangaphandle yirubha ephothiweyo ye-silicone. Umgangatho wokumelana nobushushu ngu-200°C, Isetyenziselwa ngokubanzi ukukhusela i-high-voltage ye-insulation yezixhobo zombane kunye nokuveliswa kokushisa okuphezulu, njengokukhuselwa kwe-insulating, oomatshini bombane, izixhobo zasekhaya, izixhobo zombane, njl.
