Heat-resistant electric cable feedthrough for pressure vessel - contains individual cable supports mfd. of high-temp. ceramic and sealed into body of tubular insert

摘要

The body (3) of the device sealed (8) into the wall (2) of the pressurised container has four ducts (35) for electric conductors (4) which are guided, sealed and secured by their supports (5) of refractory alumina ceramic with bores (51) soldered (52) throughout their length. The low-pressure narrow end of each support (5) abuts against an annular shoulder (37) on the inside of the body (37) and is sealed with an O-ring (10). ADVANTAGE - Electric conductors and their supports or seals can be replaced individually so that leaks or other defects can be remedied without whole feedthrough being dismantled.
