Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to shown in Fig. 1-3, a kind of halogen-free flameproof power cable, including sheath 1, insulating barrier 4 and conductor 10；It is described
The inside of sheath 1 sets external shielding layer 2, and the inside of external shielding layer 2 sets outer fire-retardant set 3；The outer fire-retardant inside of set 3 sets insulation
Layer 4, and fire-retardant set 5 in the setting of the inside of insulating barrier 4；The interior fire-retardant inside of set 5 sets sealed colloid 6, and inside sealed colloid 6
