Definitions
- ABSTRACT Electric cables of the type known as composite electrical insulated cables are insulated with a first inner layer of insulation material such as polyolefin and second outer layer of an irradiated cross-linked co-polymer of tetrafluoroethylene and hexafluoropropylene known in the trade as FEP to form a superior high temperature cable.
- first inner layer of insulation material such as polyolefin
- second outer layer of an irradiated cross-linked co-polymer of tetrafluoroethylene and hexafluoropropylene known in the trade as FEP to form a superior high temperature cable.
- cables are to be'used at high temperatures or in mechanically abrasive areas that they be coated with a material which has high mechanical strength, high operating temperature and can be easily fabricated.
- FIGURE shows a cut-away prospective view of the end of a sheet cable made in accordance with our invention.
- the cable indicated in the drawing. has a central copper conductor which may be in stranded or unstranded form, coated with a cross-linked polyolefin extruded thereon with a sheath of cross-linked FEP extruded over this insulating material.
- this outer sheath is in accordance with the present invention composed of a co-polymer' of tetrafluoroethylene and hexafluoropropylene'(FEP either in its natural state or radiation cross-linked.
- the cable of the present invention is characterized bythe novel; use of a thin sheath of cross-linked FEP over the cross-linked polyolefin material.
- a suitable F EP material is sold du l Pont de Nemours and Company of Wilmington, Delaware under the designation Teflon I00 FEP Fluorocarbon resin.
- the method of making the preferred cable consists of coating a central copper conductor with a composition consisting of a mixture of high density, high molecular weight polyethylene composition, plus ingredients such as antioxidants, cross-linking promoters and flame retardants to provide various desired characteristics as is now known to the art.
- This insulated wire is then subjected to an irradiation dose of approximately 10 megarads using high energy electrons as the irradiation source. Following irradiation of the initial polyolefin coating,
- the FEP material utilized for the purpose preferably comprises the Teflon I00 FEP fluorocarbon resin noted above.
- high energy electron, X-ra'ys or ultraviolet light is used to induce cross-linking in the FE? sheath. It is important to note that it is necessary this irradiation of this jacket occur at temperatures above the glass (internal friction) transition temperature of the FEP where cross-linking predominates over degradation.
- Such high energy electrons ,ensasi ltz realizes re s a itiqya u sqxsaff me ami- To irradiate cable coated in the described manner, it is preferable that the cable be passed under a 250 microamp 2 Mev beam at a rate such that the beam energy exposure of the completed cable is approximately 11 watts-seconds/cmF/pass.
- the cable will thus receive a total dose of approximately [.3 megarads.
- net degradation will occur.
- the temperature is raised to the glass (internal friction) transition temperature of the FEP resin (approximately 80 C.) the cross-linking of the resin becomes predominant and net degradation does not occur.
- FEP FEP, irradiated At dose rates greater than 2.6 megarads, improved elongation, resistance to deformation under load at elevated temperatures, increased stress resistances with only some slight loss in toughness.
- the sheath retains its full characteristics athigh' stresses while at low stresses there is an advantageous decrease in flow rate.
- the FEP resin of the sheath increases the cable's mechanical strength at high operating temperatures while simultaneously preventing oxidation of the underlying polyolefin thus preventing degradation of the product.
- the method of cable construction thus described permits a significant increase in the operating temperature of cables by creating a wire construction which utilizes one of the best insulations known today, namely irradiated polyolefin. It further provides elevated structural strengths, elevated operating temperatures, reduction in thickness, reduction in weight and prevents combustion of the irradiated polyolefin wire in normally combustible situations. All of this is achieved without I ture ofthe co-polymer.
- the outer layer of cross-linked FEP provides a highly adherent oxygen barrier preventing oxygen degradation at high temperatures of the inner polyolefin insulating layer. This permits a great increase in the allowable noted temperature of the wire with a reduced thickness which is essentially non-flammable and electrically inert.
- the irradiated polyolefin inner layer can be compounded with antioxidants, cross-linking promoters and flame retardants.
- a structural article of manufacture comprising at least one electric conductor and an insulating material surrounding at least a portion of said conductor, said insulating material comprising an inner layer comprising an irradiated crosslinked polyolefin and an outer layer comprising an irradiated cross-linked co-polymer of tetrafluoroethylene and hexafluoropropylene.
- a structural article comprising a first layer consisting a polyolefin and a second layer consisting of a co-polymer of tetrafluoroethylene and hexafluoropropylene, each of said layers being irradiated and thereby cross-linked throughout and each of said layers being irradiated and thereby crosslinked at least to an extent that when heated above its respective crystalline melting temperature it has form stability.
- An electric cable comprising at least one conductor, a plurality of layers of insulation surrounding said conductor, one of said layers comprising an extruded cross-linked polyolefin intimately in contact with said electric conductor and a sheath surrounding said cross-linked polyolefin material and in intimate contact with said cross-linked polyolefin, said sheath comprising an irradiated cross-linked co-polymer of tetrafluoroethylene and hexafluoropropylene.
- an electrically insulated current carrying body comprising selecting electrical current carrying bodies whose lengths are substantially greater than their widths, forming a polyolefin layer over substantially the entire length of one of said electrical current carrying bodies, irradiating and thereby cross-linking said cross-linked polyolefin, coating said polyolefin layer with a co-polymer of tetrafluoroethylene and hexafluoropropylene and, irradiating and thereby cross-linking said co-polymer, said cross-linking being accomplished above the glass transition temperature of the co-polymer.
