フィルム。Figure 1 is a cross-sectional view showing an example of the fire-resistant electric wire of this invention, and Figure 2 is a cross-sectional view showing the structure of the fire-resistant tape used to form the fire-resistant layer used in the fire-resistant electric wire of this invention. The mica plastic tape used is the tape used for the outer layer. When the mouth is used to bond the glass yarns arranged parallel to the mica foil, the part C is the tape used to attach the polyethylene tape to the glass yarns arranged parallel to each other. 2 shows a case in which a mica foil is attached to polyethylene on the opposite side of the glass yarn, and a case in which a polyethylene tape is attached to glass yarns arranged in parallel, and a mica foil is attached to the glass yarn surface. 1...
