A TUBULAR INSULATION DEVICE A HIGH VOLTAGE POWER ARRANGEMENT AND A METHOD FOR PROVIDING AN INSULATED HIGH VOLTAGE POWER CABLE

摘要

The present invention relates to a tubular electrical insulation device (108) for a cable. According to the invention the insulation device is arranged for receiving a plurality of electrical conductors segments (104) by insertion. The insulation dev ice (108) is flexible and comprises an inner circumferential electrically conductive layer (110) for establishing an electric contact to the electrical conductors (104) once inserted into the tubular electrical insulation device (108). The invention also relates to a high voltage power cable arrangement comprising a plurality of elongated electrical conductor segments (102) arranged to be placed alongside one another and in electrical contact to one another to form an inner electrical conductor (104) of a h igh voltage power cable and an elongated tubular electrical insulation device (108) arranged to house and surround the inner electrical conductor. The tubular electrical insulation device (108) is according to the present invention. The invention relates also to a method for providing a flexible insulated high voltage power cable. The method includes i. a. the step of assembling a plurality of elongated electrical cond uctor segments and an electrical insulation device on site to form the cable.
