Nonthreaded line bushings

Description

Industrial processes often take place in closed containers under increased pressure or even under vacuum conditions. When electric leads are run through, care must be taken to prevent any transfer of mass through the conductor or drops in pressure/vacuum.

BARTEC pressure-proof/vacuum-sealed line bushings provide a simple and cost-effective way of dealing with this problem. These line bushings consist essentially of a metallic sleeve which encapsulates and longitudinally seals the electric conductors in cast resin. This means that sealing is not only ensured along the lengths of the conductors but also through the conductor strands themselves. BARTEC pressure-proof/ vacuum-sealed line bushings can be designed for working temperatures of -70 °C to +150 °C depending on the application. Depending on the working temperature and ambient medium, it is possible to control pressure levels of 10^-6 mbar to 200 bar. Depending on the application, it is also possible to use BARTEC line bushings under conditions which deviate from the following technical basic data.
