Abstract
A pressure-balanced sleeve assembly for an electrical cable termination is disclosed. The sleeve assembly includes an outer sleeve surrounding the electrical cable; a chamber defined between the outer sleeve and the electrical cable; dielectric fluid contained within the chamber; and a seal that is positioned between the outer sleeve and the electrical cable to delimit and seal an end of the chamber to prevent the escapement of the dielectric fluid from the chamber, the seal being moveable along the cable in response to differences between a pressure within the chamber and a pressure outside of the chamber. Also disclosed herein is a pressure-balanced electrical cable assembly and a method of pressure-balancing a termination of an electrical cable.
Claims18
A pressure-balanced sleeve assembly for an electrical cable termination comprising:
- an outer sleeve surrounding an electrical cable;
- a chamber defined between an interior surface of the outer sleeve and an outer surface of the electrical cable;
- dielectric fluid contained within the chamber;
- and
- a seal having an opening for receiving the electrical cable, the seal being positioned between the outer sleeve and the electrical cable to delimit and seal an end of the chamber to prevent the escapement of the dielectric fluid from the end of the chamber, and the seal being moveable along the electrical cable in response to differences between a pressure within the chamber and a pressure outside of the chamber.
A pressure-balanced electrical cable assembly comprising:
- an electrical cable;
- a tube positioned over the electrical cable;
- an outer sleeve surrounding the electrical cable;
- a chamber defined between an inner surface of the outer sleeve and an outer surface of the electrical cable;
- dielectric fluid contained within the chamber;
- and
- a seal having an opening for receiving the tube, the seal being positioned between the tube and the outer sleeve to delimit and seal an end of the chamber in order to prevent the escapement of the dielectric fluid from the end of the chamber, the seal being moveable along the tube in response to differences between a pressure within the chamber and a pressure outside of the chamber.
A method of pressure-balancing a termination of an electrical cable comprising:
- positioning a seal within an outer sleeve;
- positioning the electrical cable within the outer sleeve and through a hole in the seal such that the seal is moveable along an outer surface of the electrical cable in response to differences between a pressure within a chamber and a pressure outside of the chamber;
- distributing dielectric fluid within the chamber that is defined between an inner surface of the outer sleeve and the outer surface of the electrical cable and is delimited by the seal.
