Description
Technical Field
The utility model belongs to the technical field of the enameled wire technique and specifically relates to a compound seamless membrane envelope curve of individual layer or multilayer Teflon insulated wire.
Background
In order to improve the toughness of the Teflon insulated wire rod and improve the surface wear resistance degree of the Teflon insulated wire rod, at least one layer of PET adhesive tape is wound on the periphery of the Teflon insulated wire rod generally, and because the PET adhesive tape has no viscosity, when the wire rod is bent, a gap between the adjacent PET adhesive tapes can be enlarged or even exposed out of the Teflon insulated wire rod of the body. The PET tape then lost its protective effect on the Teflon insulated wires.
Disclosure of Invention
Not enough to prior art, the utility model provides a compound seamless membrane envelope curve of individual layer or multilayer Teflon insulated wire.
The technical scheme of the utility model is that:
the utility model provides a compound seamless membrane envelope curve of individual layer or multilayer Teflon insulated wire which characterized in that: the novel PET cable comprises a Teflon insulated wire, a PET adhesive tape and a PPS adhesive tape, wherein the PET adhesive tape is wound on the periphery of the Teflon insulated wire, and the PPS adhesive tape is wound on the periphery of the PET adhesive tape.
The PET adhesive tape and the Teflon insulated wire form a helix angle of 15-70 degrees.
The Teflon insulated wire comprises a bare wire, an ETFE layer, an FEP layer and a PFA layer, wherein the ETFE layer, the FEP layer and the PFA layer are wrapped on the periphery of the bare wire.
The PET adhesive tape is provided with one layer or a plurality of layers.
The PPS adhesive tape can also be a combination of PI adhesive tape, PEN adhesive tape and PPS adhesive tape or one of the PI adhesive tape, the PEN adhesive tape and the PPS adhesive tape.
The utility model has the advantages that: ETFE plastics, FEP plastics and PFA plastics are arranged on a bare wire through an extrusion die, then PET adhesive tapes or PEN, PI and PPS adhesive tapes are wound to improve toughness and voltage resistance, and the like, in addition, the PPS hot melt adhesive tapes wrap the PET adhesive tapes to seal gaps formed when the PET adhesive tapes are wound, so that the insulating capacity, toughness and the like of the wire are further improved, and the wire is suitable for various high-speed winding automatic machines; thereby realizing the functions of dust prevention, air obstruction, radiation resistance, ultraviolet resistance, flame retardance, high temperature resistance, voltage resistance and insulation, and being particularly suitable for the wire use in special occasions of radiation research departments, nuclear power departments and the like.
