Title
(EN) A TERMINATION FOR ELECTRICAL CABLE
(FR) TERMINAISON DE CABLE ELECTRIQUE
Abstract
(EN)
A termination for an electrical power cable (1) includes a load carrying conductor (2), the termination comprising an insulating outer member (5) through which the load carrying conductor, or an extension of it, runs substantially longitudinally, and means (11) for controlling electrical stress concentrations within the outer member. Residual space (13) within the outer member is occupied by electrically insulating solid granules and interstices between the granules are filled with electrically insulating fluid. Suitably chosen granules may have better thermal conductivity, lower thermal expansion coefficient and lower cost than the fluid that might otherwise occupy the whole of the residual space, and granules are cheaper and more versatile than moulded bodies.
(FR)
La présente invention concerne une terminaison de câble (1) électrique comprenant un conducteur (2) porteur de charge, un élément (5) isolant extérieur par lequel passe sensiblement longitudinalement le conducteur porteur de charge, ou une extension de ce dernier, et des moyens (11) permettant de réguler les concentrations de contraintes électriques dans l'élément extérieur. L'espace (13) résiduel à l'intérieur de l'élément extérieur est occupé par des granules solides d'isolation électrique et les interstices situés entre les granules sont remplis de fluide d'isolation électrique. Des granules correctement choisis présentent une meilleure conductivité thermique, un coefficient de dilatation thermique inférieur et un coût inférieur par rapport au fluide qui pourrait sinon occuper l'espace résiduel entier. De plus, les granules sont moins chers et présentent des possibilités d'utilisation plus variées que les corps moulés.
