Title:
ELECTRICAL WIRE FOR IN-VEHICLE NETWORK CABLE, AND IN-VEHICLE NETWORK CABLE
Document Type and Number:
WIPO Patent Application WO/2021/193545
Kind Code:
A1
Abstract:
The present disclosure provides an electrical wire for an in-vehicle network cable, the electrical wire being light and highly bendable thin wire, and having a thin wall coating layer having uniform capacitance on a conductor having a small diameter. The electrical wire for an in-vehicle network cable retains the shape of a coating, even when exposed to an environment of 150 °C for a long period of time, thus being less likely to have defects, and has excellent electrical characteristics. The present disclosure relates to an electrical wire which is for an in-vehicle network cable, has a diameter of 0.5-1.5 mm, and is provided with a conductor and a covering material that covers the periphery of the conductor, wherein the covering material is characterized by being a tetrafluoroethylene/hexafluoropropylene/perfluoro(alkyl vinyl ether) copolymer, and including a fluororesin having a melt flow rate as measured at 372 °C and a 5 kg load of 20-40 g/10 minutes, a relative permittivity as measured at 25 °C and 6 GHz of 2.2 or less, a melting point of 250 °C or more, an MIT bending life of 2000 cycles or more, and a tensile elongation at 150 °C of 300% or more.
