PENETRATION OF ELECTRIC COMMUNICATIONS Russian patent published in 2010 - IPC H01B17/26 

FIELD: electric engineering.

SUBSTANCE: invention may be used to provide for tight passage of conductors in the form of wires, cables, harnesses in electric communications with the possibility of their replacement via sealed partition, which separates service zone from zone of ionising radiation, for instance at nuclear power plants. Substance of invention consists in the fact that proposed device comprises cylindrical body with its own biological shield and modules fixed in its ends, produced by electric conductors, tight insulators and elements of biological shield in the form of cylindrical inserts with slots for arrangement of conductors, besides modules are equipped with shell arranged in the form of location beds that are movably fixed in longitudinal direction to each other, every of which is fixed to according tight insulator only by one end. Besides elements of biological shield arranged in the form of cylindrical inserts with slots are connected to location beds by cylindrical section.

EFFECT: improved reliability of penetration in case of mechanical action, improved quality of manufacturing and assembly, increased efficiency of biological shield with simplification of penetration design, which provides for reduction of costs in commercial production.
