The present invention relates to a device for terminating cables (1), particularly for underwater termination of high voltage power cable and for conducting high voltage conductors in an electrical underwater apparatus, with the purpose of providing a liquid and water tight termination, at the same time as it provides pressure relief for vital components. According to this it is suggested that: each high voltage conductor (phase) (2a, 2b, 2c) is terminated in a separate, liquid filled and pressure compensated interior chamber (7a, 7b, 7c); conduction of the high voltage conductor from each interior chamber into attached electrical apparatus is carried out by means of a solid electrical conductor (10a, 10b, 10c), said conductor being fixed in an insulation material (11) which is liquid and gas tight, the solid electrical conductor and insulation material forming a gas and liquid tight barrier between the cable conductor and attached apparatus, and all interior chambers (7a, 7b, 7c) are adapted to a common, liquid filled and pressure compensated outer chamber (4).
