Abstract
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.
