PURPOSE:To provide a flame resisting insulated wire for which the thickness of insulation the weight and the size are reduced. CONSTITUTION:A thin flame resisting layer 2 consisting of a tape mainly composed of glass, is formed on the outer periphery of a conductor 1, which an insulating layer 3 is formed on the outer periphery of the flame resisting layer 2, and an external insulating layer 4 is formed on the outer periphery of the insulating layer 3. The insulating layer 3 is formed of polyolefine composition of thickness of 0.1-0.4mm, while the external insulating layer 4 is formed of aromatic polymer of thickness of 0.05-0.4mm. |
