FIELD: electricity.
SUBSTANCE: invention is related to electric engineering and may be used to ensure sealed input of electrical conductors through protective walls to the high-pressure area and impact loads, which contains highly toxic products. The low-frequency transition to the polluted area through the metal wall of the protective structure comprises a sealed cylindrical metal body installed in the wall with mounted electrical conductors sealed by glass insulator and shaped as conducting pins, at the body landing surface there are grooves to install O-rings in them. The body is equipped with inner partition having through holes for pins transition and each pin is soldered to the partition through its individual glass insulator. The body made of "12X18H10T" chrome-nickel steel of austenitic class forms the whole entity with the partition.
EFFECT: higher reliability of a device.
