The GTB layer is configured to surround the electrical substrate to define a protected chamber containing the electrical substrate and to inhibit ingress of a gas through the cover assembly into the protected chamber. ## Claims ### Claim 1 A cold-applied cover assembly for environmentally protecting an electrical substrate, the cold-applied cover assembly comprising: a cold-applied polymeric cover member configured to surround the electrical substrate; and a gas transmission barrier (GTB) layer configured to surround the electrical substrate to define a protected chamber containing the electrical substrate and to inhibit ingress of a gas through the cover assembly into the protected chamber. ### Claim 2 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer has a moisture vapor permeability of less than about 0.08 grams/m2/day. ### Claim 3 (depends on 2) The cold-applied cover assembly of claim 2 wherein a thickness of the GTB layer is less than about 30 microns. ### Claim 4 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer is interposed between the cold-applied polymeric cover member and the GTB layer. ### Claim 5 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer is bonded to the cold-applied polymeric cover member. ### Claim 6 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer is not bonded to the cold-applied polymeric cover member. ### Claim 7 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer includes an adhesive to secure opposed edge portions of the GTB layer to one another. ### Claim 8 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer includes a metal layer. ### Claim 9 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer includes a ceramic layer. ### Claim 10 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer includes a layer of polytetrafluoroethylene (PTFE). ### Claim 11 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer includes a polymeric film. ### Claim 12 (depends on 11) The cold-applied cover assembly of claim 11 wherein the polymeric film is a biaxially oriented polyethylene terephthalate (BoPET) film. ### Claim 13 (depends on 1) The cold-applied cover assembly of claim 1 wherein the GTB layer is a multilayer composite layer including a polymeric film substrate and a coating layer on the polymeric film substrate. ### Claim 14 (depends on 1) The cold-applied cover assembly of claim 1 wherein the cold-applied polymeric cover member is an elastomeric sleeve member defining a passage to receive the electrical substrate. ### Claim 15 (depends on 14) The cold-applied cover assembly of claim 14 wherein the elastomeric sleeve member is formed of EPDM rubber. ### Claim 16 (depends on 14) The cold-applied cover assembly of claim 14 wherein the GTB layer includes a helically wound strip. ### Claim 17 (depends on 14) The cold-applied cover assembly of claim 14 including a holdout, wherein the elastomeric sleeve member is mounted in a radially pre-expanded condition and can be selectively released from the holdout to cold shrink to a radially retracted condition on the electrical substrate. ### Claim 18 (depends on 17) The cold-applied cover assembly of claim 17 further including: an elastomeric, electrically insulating inner sleeve member mounted on the holdout in a pre-expanded condition; and an electrical shield sleeve mounted on and surrounding the inner sleeve member; wherein the cold-applied polymeric cover member and the GTB layer are mounted on and surround the electrical shield sleeve. ### Claim 19 (depends on 1) The cold-applied cover assembly of claim 1 wherein the cold-applied polymeric cover member is a wrap-around sleeve member. ### Claim 20 (depends on 19) The cold-applied cover assembly of claim 19 wherein the wrap-around sleeve member is formed of a thermoplastic elastomer. ### Claim 21 (depends on 19) The cold-applied cover assembly of claim 19 including a mass of gel sealant premounted on the wrap-around sleeve member, wherein the GTB layer is interposed between the mass of gel sealant and the wrap-around sleeve member. ### Claim 22 A method for environmentally protecting an electrical substrate, the method comprising: providing a cold-applied cover assembly including a cold-applied polymeric cover member and a gas transmission barrier (GTB) layer; and mounting the cold-applied cover assembly about the electrical substrate such that: the cold-applied polymeric cover member surrounds the electrical substrate; and the GTB layer surrounds the electrical substrate to define a protected chamber containing the electrical substrate and to inhibit ingress of a gas through the cover assembly into the protected chamber. ### Claim 23 A cold-applied cover assembly for environmentally protecting an electrical substrate, the cover assembly comprising: a cover body;
