High pressure, high voltage penetrator assembly

A high pressure, high voltage penetrator assembly upright attachable to an operation unit to which power is to be delivered or from which power is to be conveyed, the penetrator assembly comprising:

• penetrator unit for feed-through of electric power or signals,
• a funnel shaped housing with a housing chamber, the penetrator unit being located at an upper end of the chamber;
• a grid located inside the chamber transversely of a longitudinal axis of the chamber, the penetrator unit being located above the grid,
• a filter located in the chamber below the grid and above an inlet to a housing of the operation unit, and
• a sensor unit extending into the chamber from the penetrator unit and towards the grid.

High pressure, high temperature, high voltage penetrator assembly (100) is attachable to a subsea equipment vessel wall, the penetrator assembly comprising:

• a cable guiding passage interconnection piece (99) connected at one end to an exterior portion of a subsea equipment vessel wall of a subsea equipment, and communicating with an interior portion of the subsea equipment vessel through a passage in the subsea equipment vessel wall;
• a housing (101, 117) with a housing chamber (107, 116) arranged on the interconnection piece (99) at another end thereof and at a distance from an exterior location of the subsea equipment vessel wall, the housing chamber (107, 116) containing a pressure barrier (102) exhibiting an electrically insulating material (106) around the conductor pin or pins (103) penetrating the pressure barrier (102) of the penetrator assembly (100),
• the housing (101, 117) being at such a distance from the exterior portion of the subsea equipment vessel wall by means of the interconnection piece (99), and the housing exhibiting a surface area and shape so as to enable heat transfer to the seawater and thereby cooling of the housing (101, 117) and the interconnection piece (99), the seawater freely flowing about the housing (101, 117) and the interconnection piece (99) in thermal contact therewith, the cooling yielding a temperature of the housing (101, 117) and the interconnection piece (99) and their contents to be is lower than the temperature inside the subsea equipment vessel and subsea equipment vessel wall during operation of the subsea equipment.
