(FR) ISOLANTS ELECTRIQUES AMELIORES
Resumo: front page image
(EN)The present invention relates to a barrier (1) for an insulator having a central portion or stem with a plurality of sheds extending therefrom. The barrier (1) is, in use, located between adjacent sheds of the insulator and comprises a sheet (2) of dielectric material having one or more discontinuities in its surface. The discontinuities can be in the form of holes (3, 24) in the surface or in the form of a joint between cut edges (2) of the barrier (1).
(FR)L'invention décrit une barrière (1) pour isolant dont la partie centrale est pourvue d'une pluralité de protections faisant saillie. En utilisation, la barrière (1) est située entre les protections contiguës de l'isolant et comprend une bande (2) de matériau diélectrique comportant une ou plusieurs discontinuités sur sa surface. Les discontinuités peuvent être sous forme de trous (3, 24) dans la surface ou sous forme d'un joint entre les rebords coupés (2) de la barrière (1).
