A capacitor assembly and a method of assembling a capacitor assembly are provided. The capacitor assembly has at least two capacitor stacks, which have a layer structure including a top layer and a bottom layer. A support assembly supports the capacitor stacks. The capacitor stacks are stacked on top of each other in the support assembly. The support assembly has a compression member which compresses the at least two capacitor stacks in a direction substantially perpendicular to the layer structure. A pressure distribution arrangement adjusts the distribution of the pressure applied to the capacitor stacks by the compression member. Further, a subsea device in particular a subsea variable speed drive is disclosed.

A subsea power distribution system is provided. The subsea power distribution system has a power input for receiving electrical power at a first voltage level and an input transformer coupled to the power input and adapted to transform received electrical power to a second voltage level which is lower than the first voltage level. A distribution circuit distributes received electrical power to two or more power distribution paths. At least one rectifier unit is provided that receives transformed electrical power from the input transformer and outputs rectified electrical power. The two or more power distribution paths each have an inverter configured to receive rectified electrical power from the rectifier unit and to output AC electrical power at a third voltage level, and a distribution path transformer coupled to the respective inverter and configured to transform the output AC electric power to a fourth voltage level which is higher than the third voltage level.

The present invention relates a subsea fuse device (100, 200) exposed to a high ambient pressure when deployed. The fuse device comprises a metallic fuse housing (107, 207) enclosing a low-pressure hollow space (110, 210) and a fuse (105, 205) arranged in the low-pressure hollow space, the fuse having two electrical connectors, wherein one of the electrical connectors of the fuse (151, 251) is electrically and thermoconductively coupled to the metallic fuse housing so as to provide an electrical connection between the fuse connector and the housing and to dissipate heat from the fuse.
