Zusammenfassung: | The proposed fire-resistant electric cable contains a core consisting of one or several separate or twisted conductors with insulating coating of silicon rubber, with screening braiding or without such a braiding, a reinforcing layer, and a sheath. The reinforcing layer is constructed as a layer of glass-cloth that is impregnated with fire-resistant material and wound onto the insulated core of the cable. The sheath is made from fire-resistant material based on cross-linked polymer, without chlorine or chlorine compounds, or from fire-resistant material produced in coke processing. |
