  • SUBSEA SUBSTATION SYSTEM
    Publication number: 20240421568
    Abstract: A subsea substation system including: an oil-filled water impermeable enclosure; an AC-transformer, and at least one overcurrent device electrically connected to the AC-transformer, the at least one overcurrent device, the AC-transformer, and the electrical connections between them are accommodated in the oil-filled water impermeable enclosure, wherein the enclosure includes thermal zones within the enclosure, wherein the AC-transformer is arranged in a first thermal zone and the overcurrent devices are arranged in a second thermal zone of the enclosure, a thermal layer separate the first thermal zone and the second thermal zone, the at least one thermal layer is configured to allow oil flow between the thermal zones while reducing heat flow between the zones.
