Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figure 1. The utility model provides a technical solution: a low-smoke, halogen-free, high-performance, fire-proof wire and cable, comprising a wire and cable body 1, the wire and cable body 1 comprising a conductor 2, a plurality of conductors 2, and further comprising: a limiting component 3, the limiting component 3 is coated on the outside of the conductor 2, and the limiting component 3 is used to separate and limit the plurality of limiting components 3; a heat insulation layer 4, the heat insulation layer 4 is coated on the outer wall surface of the limiting component 3, and the heat insulation layer 4 is used to reduce the damage of the conductor 2 caused by the external high temperature; and a fireproof layer 5, the fireproof layer 5 is coated on the outer wall surface of the heat insulation layer 4, and the fireproof layer 5 is used to slow down the spread of fire, control combustion, and reduce the release of harmful gases;

Through the multiple wires 2 in the wire and cable main body 1, signals can be transmitted and the limiting component 3 can be conveniently covered. Then, through the limiting component 3, the multiple wires 2 can be separated and limited, so that each wire 2 can be in a stable state, thereby reducing mutual interference between them. Since the thermal insulation layer 4 is coated on the outer wall surface of the limiting component 3, and the fireproof layer 5 is coated on the outer wall surface of the thermal insulation layer 4, the thermal insulation layer 4 can block external heat, thereby reducing the influence of external heat on the wire 2, thereby improving the stability of the signal transmitted by the wire 2. At the same time, the fireproof layer 5 can slow down the spread of fire, control combustion, and reduce the release of harmful gases, further improving the safety and life of the wire and cable main body 1.

Referring to FIG. 1 and FIG. 2 , the limit assembly 3 includes an insulating inner sheath 31 , the inner cavity of the insulating inner sheath 31 is provided with a partition frame 32 for separating a plurality of wires 2 , and the gap between the inner cavity of the partition frame 32 and the wires 2 is filled with a flame retardant rubber filler 33 ;

The insulating inner sheath 31 in the limiting component 3 can not only resist the influence of external current on the wire 2, but also wrap and protect the partition frame 32. Since the inner cavity of the insulating inner sheath 31 is provided with a partition frame 32 for separating multiple wires 2, and the gap between the inner cavity of the partition frame 32 and the wire 2 is filled with a flame-retardant rubber filler 33, the partition frame 32 can not only separate the multiple wires 2, but also cooperate with the flame-retardant rubber filler 33 to limit the separated wires 2, thereby improving the stability of the wire 2 when used.

Referring to FIG. 2 and FIG. 3 , the heat insulation layer 4 includes an aerogel felt layer 43, which is disposed on the outer wall surface of the insulating inner jacket 31, and a high temperature resistant heat insulation cloth layer 41 is disposed outside the aerogel felt layer 43. The heat insulation layer 4 also includes a copper braided layer 42, which is disposed between the aerogel felt layer 43 and the high temperature resistant heat insulation cloth layer 41;

The aerogel felt layer 43 in the thermal insulation layer 4 can not only cover the outer wall surface of the insulating inner sheath 31, but also effectively prevent the spread of fire and protect people's lives and property. The high-temperature resistant thermal insulation cloth layer 41 can effectively resist the penetration of external high temperature, and thus can cooperate with the aerogel felt layer 43 to achieve the purpose of double thermal insulation, so as to protect the wire 2. At the same time, the copper braided layer 42 can serve the purpose of skeleton support, thereby improving the deformation resistance of the wire and cable main body 1 and further improving the service life of the wire and cable main body 1.

Referring to Figures 3 and 4, the fireproof layer 5 includes a silicate glass fiber layer 53 disposed on the outer wall surface of the high temperature resistant heat insulation cloth layer 41, and the outer wall surface of the silicate glass fiber layer 53 is compounded with a nano aluminum hydroxide layer 52. The fireproof layer 5 also includes a PE flame retardant protective cover 51, and the PE flame retardant protective cover 51 is disposed on the outer wall surface of the nano aluminum hydroxide layer 52;

The silicate glass fiber layer 53 in the fireproof layer 5 can not only adhere to the outer surface of the high-temperature resistant heat-insulating cloth layer 41, but also achieve the purpose of fireproofing. Since the silicate glass fiber in the silicate glass fiber layer 53 is a common halogen-free flame retardant material, it can be used to enhance the flame retardant properties of polymer-based composite materials. Since the outer wall surface of the silicate glass fiber layer 53 is compounded with a nano aluminum hydroxide layer 52, when the temperature rises to a certain level, the nano aluminum hydroxide layer 52 will decompose and release moisture, thereby absorbing heat and reducing the burning rate of the material, further reducing the risk of fire and reducing the impact on the environment. The PE flame retardant protective cover 51 can not only achieve the purpose of preliminary flame retardancy, but also provide preliminary protection, thereby improving the service life and safety of the fireproof layer 5.

During operation, the multiple wires 2 in the wire and cable main body 1 can not only transmit signals, but also facilitate the covering of the limiting component 3. Then, the multiple wires 2 can be separated and limited by the limiting component 3, so that each wire 2 can be in a stable state, thereby reducing mutual interference between them. Since the thermal insulation layer 4 is coated on the outer wall surface of the limiting component 3, and the fireproof layer 5 is coated on the outer wall surface of the thermal insulation layer 4, the thermal insulation layer 4 can block external heat, thereby reducing the influence of external heat on the wire 2, thereby improving the stability of the signal transmitted by the wire 2. At the same time, the fireproof layer 5 can slow down the spread of fire, control combustion, and reduce the release of harmful gases, further improving the safety and life of the wire and cable main body 1.

The insulating inner sheath 31 in the limiting component 3 can not only resist the influence of external current on the wire 2, but also wrap and protect the partition frame 32. Since the inner cavity of the insulating inner sheath 31 is provided with a partition frame 32 for separating multiple wires 2, and the gap between the inner cavity of the partition frame 32 and the wire 2 is filled with a flame-retardant rubber filler 33, the partition frame 32 can not only separate the multiple wires 2, but also cooperate with the flame-retardant rubber filler 33 to limit the separated wires 2, thereby improving the stability of the wire 2 when used.

The aerogel felt layer 43 in the thermal insulation layer 4 can not only cover the outer wall surface of the insulating inner sheath 31, but also effectively prevent the spread of fire and protect people's lives and property. The high-temperature resistant thermal insulation cloth layer 41 can effectively resist the penetration of external high temperature, and thus can cooperate with the aerogel felt layer 43 to achieve the purpose of double thermal insulation, so as to protect the wire 2. At the same time, the copper braided layer 42 can serve the purpose of skeleton support, thereby improving the deformation resistance of the wire and cable main body 1 and further improving the service life of the wire and cable main body 1.

The silicate glass fiber layer 53 in the fireproof layer 5 can not only adhere to the outer surface of the high-temperature resistant heat-insulating cloth layer 41, but also achieve the purpose of fireproofing. Since the silicate glass fiber in the silicate glass fiber layer 53 is a common halogen-free flame retardant material, it can be used to enhance the flame retardant properties of polymer-based composite materials. Since the outer wall surface of the silicate glass fiber layer 53 is compounded with a nano aluminum hydroxide layer 52, when the temperature rises to a certain level, the nano aluminum hydroxide layer 52 will decompose and release moisture, thereby absorbing heat and reducing the burning rate of the material, further reducing the risk of fire and reducing the impact on the environment. The PE flame retardant protective cover 51 can not only achieve the purpose of preliminary flame retardancy, but also provide preliminary protection, thereby improving the service life and safety of the fireproof layer 5.

In summary, the device can not only keep each conductor 2 in a stable state, thereby reducing mutual interference between them, but also reduce the impact of external heat on the conductor 2, while also slowing down the spread of fire, controlling combustion and reducing the release of harmful gases, further improving the safety and life of the wire and cable main body 1.
