Embodiment 1
[0038] Embodiment one: see figure 1 , an environment-friendly composite functional flexible fireproof single-core cable, which sequentially includes a conductor core 1, a fireproof layer 2, an insulating layer 3, a waterproof layer 4, a fireproof inner sheath 5 and a fireproof outer sheath 6 from inside to outside. Among them, the conductor core 1 is made of a number of soft round copper wires with the same diameter in a regular and concentric layered twist; the refractory layer 2 is processed by synthetic mineral refractory composite tape; the insulating layer 3 is made of 150 ° C It is processed by irradiation cross-linked polyolefin halogen-free insulating material; the waterproof layer 4 is processed by heat-insulating, halogen-free, low-smoke and high flame-retardant material; the fire-proof inner sheath 5 is processed by high-temperature-resistant high-strength carbon fiber composite tape; The outer sheath 6 is made of environmentally friendly, highly flame-retardant, lo...
Embodiment 2
[0039] Embodiment two: see figure 2, an environment-friendly composite function flexible fireproof multi-core cable, which is composed of a cable inner core and an insulating and protective outer layer, the insulating and protective outer layer is wrapped around multiple cable inner cores, and fillers are arranged between the multiple cable inner cores 7. The cable inner core includes conductor core 1, refractory layer 2 and insulating layer 3. There are two or more cable inner cores (4 cable inner cores in the figure), and the outer insulation protection layer includes waterproof layer 4. Fireproof Inner sheath 5 and fireproof outer sheath 6. Among them, the conductor core 1 is made of a number of soft round copper wires with the same diameter in a regular and concentric layered twist; the refractory layer 2 is processed by synthetic mineral refractory composite tape; the insulating layer 3 is made of 150 ° C It is processed by irradiation cross-linked polyolefin halogen-fr...
