FIELD: electrical engineering; stuffing conductors to enter them in hermetically sealed premises or spaces at nuclear power stations or other projects.
SUBSTANCE: proposed sealed cable entry has cylindrical case incorporating flanges with holes wherein metal-sheathed mineral-insulation covered seven-conductor cables are soldered at its butt-ends, this metal sheath being electrically connected to case flanges. Conductors are disposed about central cable conductors to form screens and are electrically connected to screens of leading-in cables; central conductors of mineral-insulation covered cables are connected to those of leading-in cables. Every conductor of common-screen leading-in cable is electrically connected to one central conductor of mineral-insulation covered seven-conductor cable, and leading-in cable screen is connected to all external conductors of cable around central conductor.
EFFECT: enhanced noise immunity of screened-conductor leading-in cables in radio-frequency data transmission range.
