Abstract
A barrier layer is used against migration of a substance, wherein the barrier layer is arranged in a cable and/or around an electrical conductor, and the barrier layer contains polyethylene furanoate or solely contains polyethylene furanoate. Furthermore, an electrical conductor, a cable, and a method are used for manufacturing a coated cable or a coated hose and a use of polyethylene furanoate as a barrier layer.
Claims12
A barrier layer against migration of a substance, wherein the barrier layer is arranged in a cable and/or around an electrical conductor, wherein the barrier layer comprises polyethylene furanoate, and wherein the barrier layer is manufactured by extrusion together with a sheath layer in one operation, so that the barrier layer is permanently joined to the sheath layer.
An electrical conductor for transmitting power and/or information, said electrical conductor comprising:
- a barrier layer, wherein the barrier layer comprises polyethylene furanoate, so that the electrical conductor is protected against migration of a substance and is flexible in bending, and wherein the barrier layer is manufactured by extrusion together with a sheath layer in one operation, so that the barrier layer is permanently joined to the sheath layer.
A method for manufacturing a coated cable by an extrusion device, said method comprising:
- introducing a continuous electrical conductor into an extrusion device, and extruding a first molding compound to form a sheath layer, and a second molding compound, wherein the second molding compound comprises polyethylene furanoate, to form a barrier layer of a cable, wherein the extrusion of the first molding compound and of the second molding compound takes place in one operation, and discharging the coated cable, so that the coated cable comprises the barrier layer and is flexible in bending.
