Abstract
A cable (1) entering a submersible machine, such as an electrically driven pump, a turbine etc., is surrounded by a collar (3) of a rigid material, and the collar (3) is secured to the machine shell (2) by bolts (4). Two sockets (5) and (6) of an elastic material surround the cable (1), one of them mounted in the shell (2) and the other in the collar (3). A ring (8) of a rigid material is arranged between the two sockets (5) and (6). The collar (3), during mounting, is moved towards and into contact with the shell (2), thereby causing the sockets (5) and (6) to be compressed axially and expanded radially so that the cable (1) is secured and sealed.
