  • Patent number: 4045611
    Abstract: A hermetic lead wire for use in conducting electricity to a motor in a hermetically sealed system such as a refrigeration system is formed with an electrically wound, laminated flexible foil tape surrounding an internal stranded conductor. The laminated tape is formed with an inner nonwoven fibrous layer of polyester fibers for interlocking with the conductor when melted by a hot stripping tool. An outer impervious foil layer of polyester on said laminated tape provides a dielectric shield for the wire. Preferably, the laminated tape is helically wound about the conductor and is covered with an outer flexible braided sheath of polyester filaments.
