Abstract: Introduce the materials and structures of environmentally friendly mineral insulation fire cables, through designing mineral fire prevention insulating layers, thermosetting polymer protective layers, inorganic fiber filler, low smoke halogen-free silicon porcelain insulation layer, metal armor fireproof layer, fire prevention layer, and metal armor fireproof layer. The composite refractory structure is composed of low -smoke halogen-free environmental protection external care layer, realizing the environmental protection of cable fire resistance and low toxic environmental protection performance, low toxicity, and fire-resistant cable.
