A pressure compensator is configured to compensate for volume variations of an insulation medium of a subsea installation. The pressure compensator includes a first bellows chamber having walls and a first bellows part. The first bellows chamber is in flow connection with an insulation medium chamber of the subsea installation, and the walls of the first bellows chamber are configured to separate the insulating medium from surroundings. The first bellows chamber is surrounded by a second bellows chamber having walls and a second bellows part. The second bellows chamber is configured to form a closed intermediate space around the first bellows chamber. The walls of the second bellows chamber are configured to separate at least the bellows parts of the first bellows chamber from the surrounding sea water. The second bellows chamber is further filled with an intermediate medium.
