    摘要: An electrical cable for use in submersible well pumps in oil and gas well environments is provided having an electrical conductor core which is surrounded by an insulating layer of cross-linked polyethylene. A barrier layer surrounds the cross-linked polyethylene insulating layer. The barrier layer is impermeable to oil and other liquid hydrocarbons, but is permeable to low molecular gases. The barrier layer is preferably formed from a fluoropolymer and is surrounded by a polymeric protective layer. An adhesive layer attaches the barrier layer to the insulating layer.
