The invention relates to a medium-voltage power transmission fire-resistant cable, which is characterized in that the outer fire-resistant layer of the medium-voltage cable core is made of fire-resistant inorganic fiber heat insulation layer on the inner side, and the outer side is a soft thermosetting elastomer for normal use. The composite fire-resistant and heat-insulating layer of the heat layer, the thermosetting elastomer, is composed of 30-50wt% silicon-based elastic material, 40-60wt% inorganic filler, 5-15wt% medium and low temperature frit, 4-10wt% vulcanizing agent, It is made by mixing extrusion molding and vulcanization. The composite fire-resistant and heat-insulating layer is a relatively soft sheath material when it is not exposed to flames, which can ensure good bending performance of the refractory structure in normal conditions, and quickly transforms into a shell-and-tube refractory and heat-insulating structure when it encounters fire or high temperature. In the fire-fighting environment, it can still maintain a certain period of time without being damaged, effectively preventing damage to the inner insulation caused by flames or high temperatures. When the flame temperature of the outer layer is 850°C, the temperature of the inner insulation surface is lower than 180°C. This fire-resistant and heat-insulating structure can be applied according to conventional cable production methods, and the production efficiency is extremely high.
