High pressure transits are designed for situations where the standard MCT cable transits (5 bar) no longer meet the requirements, in very high pressure conditions such as in offshore or submarines. MCT Brattberg has a number of different high pressure transits, all of which are custom made. The RGPM and RGPH are transits for multiple cables up to a continuous pressure of 15 bar. When you have to feed a cable under extreme conditions, the LSJ and PHP transits are the right choice. Both tested to a pressure of 90 bar.
In addition to the penetrations, MCT also has an Encapsulation option, which seals sensors and connectors for very high pressure (50 bar) conditions.
