Abstract
A non-halogen flame-retardant insulated electric wire includes a conductor and a crosslinked single-layer or a multilayer insulating layer on an outer periphery of the conductor. The insulating layer has a tensile elastic modulus of 500 MPa or more and an elongation at break of 120% or less in a tensile test performed at a displacement rate of 200 mm/min, and has a storage elastic modulus at 125° C. of 3×106 Pa or more in a dynamic viscoelasticity test.
Claims8
A non-halogen flame-retardant insulated electric wire, comprising:
