Process for insulating high voltage electrical conducting media

摘要

A process for insulating high voltage conducting media by insulating such media with a silicone rubber composition capable of being converted to a rubbery elastomer superior in high voltage electrical insulating characteristics is provided. The composition comprises the following components (a) to (e) and not containing a platinum catalayst: (a) 100 parts by weight of an organopolysiloxane gum; (b) 10-100 parts by weight of a finely divided silica filler; (c) 15-300 parts by weight of aluminum hydroxide; (d) 1-20 parts by weight of a OH terminated organosilane or organosiloxane oligomer; and (e) 0.05-6 parts by weight of an organic peroxide.
