<p>Spacer for a gas-insulation electrical bushing insulator. This spacer is in the form of a wheel with an annular hub 6 covered on its perimeter by a tyre (band) 65 having wide flanks 14, 15 forming, on either side, two annular seals without discontinuity. It has the advantage of halving the number of active-seal planes and, consequently reducing, by the same proportion, the dangers of leakage or of inclusion of air. <IMAGE></p> |
