Silicone sponge rabha ndiyo yakanakira insulating zvinhu muwaya uye tambo indasitiri. High-temperature vulcanized silicone foam rabha inoshingirira kupisa-inoshingirira, ozone-inoshingirira, inodzivirira mamiriro ekunze-uye ine magetsi akanakisa. Kana ichipisa nekuora, iyo silica yakasara inogadzirwa ichiri kushanda se insulator. Iyo inewo yakanaka yekupisa conductivity uye inogona kukurumidza kubvisa kupisa kunokonzerwa nemutoro wezvino. Yayo arc resistance performance yakanaka kwazvo. Pasi pemamiriro ekubuda kwehalo, inogona kuramba ichishandiswa kwemaawa 1000, nepo general organic rubber insulated tambo dzinogona kushandiswa kwemaminetsi makumi matatu chete.
Naizvozvo, waya netambo dzinonyanya kuiswa nepamusoro-tembiricha yakanyungudutswa yesilicone rabha inosanganisira tambo dzemagetsi, tambo dzengarava, tambo dzekudziisa, tambo dzekubatidza moto, tambo dzeatomu dzemagetsi emagetsi, waya dzemuchadenga, nezvimwewo. Murubha rinoshandiswa mu high{2}}voltage insulated circuits, kuwedzera kwealuminiyamu inodzivirira hydrsion, kuwedzera kwealuminiyamu yemagetsi ekudzivirira hydrsion uye arc.
