Abstract

The electrical insulator for high tension has a central support of vitreous resin (1) and finning of EPR elastomer (5, 7), in which the fins are applied to the support: globally, in a single body, or individually or in groups and directly, or with interposition of a tubular sleeve (3) of said EPR elastomer. The parts are assembled into a single whole by means of an appropriate olefin polymer-based self-vulcanising adhesive mixture. The pertinent production process provides for the formation and vulcanisation of the fins (5, 7) and of the tubular sleeve (3) according to choice: separately - with subsequent assembly onto the support (1, or 1 + 3) - or directly onto the actual support (1, or 1 + 3). The insulators obtained in this manner are characterized by a very low weight/mechanical strength ratio, and by there ability to tolerate the intense operational vibrations, as compared with the conventional porcelain insulators. Moreover, they exhibit substantial properties of resistance to aging and to surface discharges, and high auto-extinction capability, as compared with insulators made from organic material of the prior art.
