Problems solved by technology

[0002] At present, cables are widely used in power, communication and related transmission projects. They are usually rope-like cables twisted by several or several groups of wires, each of which is twisted with at least two wires. Each group of wires is insulated from each other and often wrapped around It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The cables in the prior art do not have good fire resistance and fire extinguishing functions. When a fire occurs or special production requires fire and pressure resistance, ordinary cables The cables are easily melted, exposing the conductors, causing electrical accidents or making electrical failures, and may even cause serious fire accidents
[0003] In addition, mice biting cables are also the main cause of electrical accidents.

Embodiment 1

[0016] Such as figure 1 Shown is a cable device with anti-rat bite, high-efficiency heat dissipation and fire prevention function, including a cable core 1, an insulating layer 2, a flame-retardant line 3 and a protective layer 4, and a flame-retardant line 3 in the center of the cable. The flame retardant lines 3 are surrounded by at least three cable cores 1 wrapped with an insulating layer 2, and the periphery of the cable core 1 wrapped with an insulating layer 2 is surrounded by at least fifteen flame retardant lines 3, and the outermost layer of the cable is a protective Layer 4, the protective layer 4 is provided with anti-rat biting steel wire netting 6, and the outer layer of the anti-rat biting steel wire netting 6 is provided with anti-bite vertical ribs 7.

Embodiment 2

[0018] Such as figure 1 Shown is a cable device with anti-mouse bite, high-efficiency heat dissipation and fire prevention function. On the basis of Example 1, the inside of the flame-retardant line 3 is filled with fire-extinguishing powder, and the outside of the flame-retardant line 3 is a rubber layer. When a fire breaks out, the fire extinguishing powder can be filled in the flame retardant line 3 in time.

Embodiment 3

[0020] Such as figure 1 Shown is a cable device with anti-rat bite, high-efficiency heat dissipation and fire prevention function. On the basis of Example 1, the diameter of the flame-retardant line 3 in the center of the cable is the diameter of the flame-retardant line 3 surrounded by the cable core 1. times, the larger the inner diameter of the flame retardant line 3, the more fire extinguishing powder is filled inside, and the fire extinguishing from the inside of the cable is the most effective.

Abstract

The invention discloses a rat bite resistant cable device with efficient heat dissipation and a fire prevention function, which comprises cable cores, insulating layers, flame retardant lines and a protection layer, and is characterized in that the cable center is provided with one flame retardant line, the periphery of the flame retardant line is provided with at least one cable core wrapped with the insulating layer in a surrounding mode, the periphery of the cable core wrapped with the insulating layer is provided with at least one flame retardant line in a surrounding mode, the outermost layer of the cable is the protection layer, the protection layer is internally provided with a rat bite resistant steel wire sleeve net, and the other layer of the rat bite resistant sleeve net is provided with bite resistant vertical ribs. The outer layer of the cable is provided with heat dissipation bulges, thereby playing a role of efficient heat dissipation, and preventing a fire caused by overheat of the cable. The internal part of the cable is provided with the flame retardant lines with a fire extinguishing function. When the cable is on fire, a fire extinguishing powder agent in the flame retardant lines can extinguish the fire effectively and timely.
