Abstract
An assembly for use with an oil-filled cable termination includes a cable gland, a cable received in the cable gland, and a stress cone received around the cable and spaced apart from the cable gland. The cable includes a central conductor and a polymeric insulation layer surrounding the central conductor. A lug is spaced apart from the stress cone and includes a barrel portion with the central conductor of the cable received in the barrel portion. An oil barrier system including an oil barrier layer surrounds the polymeric insulation layer of the cable between the stress cone and the lug.
Claims18
An assembly for use with an oil-filled cable termination, the assembly comprising:
- a cable gland;
- a base plate, wherein the cable gland is on the base plate;
- a cable received in the cable gland, the cable comprising a central conductor and a polymeric insulation layer surrounding the central conductor;
- a stress cone received around the cable and spaced apart from the cable gland;
- a lug spaced apart from the stress cone, the lug comprising a first end portion comprising a barrel and an opposite second end portion, with the central conductor of the cable received in the barrel;
- an oil barrier system comprising an oil barrier layer surrounding the polymeric insulation layer of the cable between the stress cone and the lug;
- and
- an insulator housing mounted on the base plate and/or the cable gland and surrounding the stress cone and at least a portion of the cable gland and the first end portion of the lug, wherein the insulator housing is configured to receive and hold oil with the oil directly contacting the oil barrier layer.
A method for preparing an oil-filled cable termination assembly, the method comprising:
- providing a cable having a distal end portion and comprising a central conductor and a polymeric insulation layer surrounding the central conductor;
- installing an oil barrier layer on the polymeric insulation layer of the cable;
- receiving the cable in a cable gland;
- receiving a stress cone around the cable with the stress cone spaced apart from the cable gland;
- receiving the cable gland on a base plate;
- mounting an insulator housing on the base plate and/or the cable gland;
- and
- filling an interior cavity of the insulator housing with oil such that the oil directly contacts the oil barrier layer;
- wherein:
- the oil barrier layer comprises a first end portion and an opposite second end portion;
- the first end portion of the oil barrier layer is at the distal end portion of the cable;
- and
- the oil barrier layer extends from the distal end portion of the cable to the stress cone.
