<p>Provided is an insulation material, which ensures maintenance of functions for an insulation wire, cable and cable core in a significantly extended range of temperatures, and is cost-efficient. The insulation material for use in stabilization upon a fire accident is based on polymer synthetic resins to which different types of glass particles having different softening points are added. In the insulation material, the glass particles include three types of glass having a different softening point from one another, which are comprised of a first type of glass having a softening point of about 470 deg.C or less, a second type of glass having a softening point of about 470 deg.C to about 620deg.C, and a third type of glass having a softening point of about 760 deg.C or higher.</p> |
