FIELD: machine building.
SUBSTANCE: permanent electrical insulating joint comprises two metal nozzles, one of which is made with a socket, between which there is a ring installed made of dielectric material. The other nozzle is made with the reduced diametre, in gap produced with an internal surface of socket and external surface of reduced diametre of nozzle, there is a ring made of dielectric material, and space between them is filled with cloth impregnated with epoxy resins. Edges of nozzle with a reduced diametre are rolled to make a reliable lock joint.
EFFECT: invention simplifies design of permanent coupling joint and increases its reliability.
