Submarines
Over 500 naval vessels worldwide need to be at sea for long periods without refueling. To achieve this, they are often powered by small nuclear reactors. Most are submarines but they also include other naval vessels, ranging from civil icebreakers to aircraft carriers.
In order to control the reactor, cable penetrations safely conduct electricity through the fire-protective, pressure resistant and hermetically sealed walls of bulkhead compartment while – in cases of accidents –preventing steam, pressure and radioactivity from escaping.
The vital role these special ships play, the fact that the lives of the crew depend on its proper functioning, and the dangers inherent in a nuclear reactor underline the importance of product safety and quality for nuclear powered ships. This is especially critical in case of an accident.
Highest quality standards combined with leading engineering know-how have made us the first-choice partner for carriers and navies around the world.

Product Description
A penetration module for submarines mainly consists of
- A metal housing with sealed-in conductors
- Two glass-to-metal-seal barriers (in compression technique)
- Mating connectors, cabled according to customer specifications on demand
Product Advantages
Our hermetically sealed penetrations for use in submarines and other naval vessels have the following advantages:
- Pressure resistant
- Flame-retardant, obtaining electrical functionality for several hours at elevated temperatures
- Highest quality standards combined with leading engineering know-how
- Virtually no aging of the used conductors and glass seal
- Sealed conductors carry up to 1000 Amperes while permanently retaining hermeticity
- A lifetime of up to 40 years (qualified life)
The penetration systems also include connectors qualified for use in nuclear powered submarines. The plugs are easy to connect and allow fast exchange of tails in case of a system modification.
Applications
Our glass-to-metal sealed penetrations are used for Light Water Reactors (LWR) such as Boiling Water Reactors (BWT) and Pressurized Water Reactors (PWT) on nuclear driven ships and submarines.
Technology
Penetrations for use in submarines involve compression glass-to-metal sealing (GTMS) technology. Please contact our sales department for further details, or refer to our technology pages for more information about GTMS.
