PROBLEM TO BE SOLVED: To provide a sufficiently flexible fire resistant wire keeping an excellent withstand voltage characteristics by using a twisted wire conductor in the same manner as by using a single wire conductor. SOLUTION: This fire resistance wire comprises, each on a linear conductor, power mica, especially a fire resistance rubber layer 3a made of silicone rubber filled with powder mica of grain size 50 to 2,500 μm, a mica tape layer 3b made by winding a tape on which flake mica is adhered on a reinforcement base material on the fire resistance rubber layer, an insulation layer 4 made by synthetic resin, and an additionally a sheath 5 is provided as required. |
