Seal systems for oil-filled cable terminations and assemblies and methods including the same

A method for forming a seal system for an oil-filled cable termination comprising a cable that is received through each of a cable gland and a stress cone that is spaced apart from the cable gland, the method comprising:

• forming a first oil seal layer around the cable by heating a first heat shrinkable tube, wherein the first oil seal layer overlaps and contacts the cable gland and is spaced apart from the stress cone;
• forming a second oil seal layer over the first oil seal layer by heating a second heat shrinkable tube, wherein the second oil seal layer extends between the cable gland and the stress cone;
• and
• forming a third oil seal layer over the second oil seal layer by heating a third heat shrinkable tube, wherein the third oil seal layer extends between the cable gland and the stress cone.

An assembly for use with an oil-filled cable termination, the assembly comprising:

• a cable gland comprising a plate portion and a tubular portion, the tubular portion including a first end and an opposite second end, the plate portion surrounding the tubular portion between the first and second ends thereof;
• a cable received in the tubular portion of the cable gland;
• a base plate comprising a seat defining an opening, wherein the cable gland plate portion is configured to be held on the base plate seat such that the cable and the cable gland tubular portion extend through the opening;
• and
• first and second grommets, the first grommet configured to be received in the cable gland tubular portion at the first end thereof and the second grommet configured to be received in the cable gland tubular portion at the second end thereof, the first and second grommets configured to hold the cable gland tubular portion in position such that the first end of the cable gland tubular portion is above the base plate and the second end of the cable gland tubular portion is below the base plate.
