<p>The invention relates to an insulator for an electrical conductor provided with an outer shield, especially a so-called coaxial cable or shielded twin cable, in order to achieve an insulation at the shield that insulates against DC and low frequency AC signals transforming through the conductor and that includes a first and a second element (3, 4) formed from electrically conducting material that by means of a dielectric (5) are electrically insulated and delineated from one another and that are intended to be connected between an interruption at the shield or between the shield and an external earth connection. To achieve an insulator of the type that uses a standard type of capacitive element and that is simple and cheap to produce at the same time as it only has small dimensions, the elements (3, 4) are, according to the invention, arranged with one or several continuous openings running through them for passing the conductor through the elements and that the delineation between the elements defined by means of the dielectric (5) is crossed by one or more discrete capacitive elements (6) that are electrically connected between the first and second elements.</p> |
