Therefore, in the present day of rapid development of information technology, in order to ensure that the requirements on reliability of information transmission and power supply are higher and higher, the requirements on the performance of the cable are put forward, and the performance indexes of the cable performance are presented in the aspects of fireproof performance, dampproof performance, explosion-proof performance, corrosion resistance, temperature performance, expansion performance, tensile strength, elasticity, plasticity, hardness, toughness, fatigue strength and the like besides the conductivity of the cable, wherein the requirements on the fireproof performance of the cable are the most strict, statistics is carried out according to relevant departments of the country, in the fire cause, the fire caused by an electric circuit reaches more than 50%, and the cable serving as a main body in the electric circuit is mainly arranged underground, so that the cable is difficult to be well protected.
In the prior art, most of cables wrapped by rubber materials are heated easily when the circuit load is overlarge or short circuit occurs, so that the cables are burnt, and accordingly casualties are caused due to fire, and meanwhile, the problem of large-scale power failure caused by power short circuit is caused due to cable faults.
Disclosure of Invention
Based on the above, the utility model aims to provide a fire-proof cable so as to solve the technical problem that the cable is spontaneous combustion and causes casualties caused by fire disaster when a heating state occurs when the circuit is overloaded or short-circuited.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a fire prevention cable, includes ceramic mica tape, ceramic mica tape's inside is provided with the filler, the cable core is installed to the inside setting of filler, ceramic mica tape's outside sets up installs fire prevention mud, this is the insulating layer of installing in outside of fire prevention mud, the shielding layer is installed in the outside setting of insulating layer, the fire-retardant layer is installed in the outside setting of shielding layer, the flame retardant coating is installed in the outside setting of fire-retardant layer, the outside setting of flame retardant layer is installed the flame retardant coating, the hydrophobic area is installed to the outside setting of flame retardant coating, glass fiber protection area is installed to the outside setting of hydrophobic area.
By adopting the technical scheme, the wear-resisting property of the glass fiber protecting belt is used for preventing the cable from being damaged outside, and the hydrophobic belt prevents rainwater or dew from entering and preventing the cable from being short-circuited.
The utility model further provides that the filler of the filler is a high-temperature resistant insulating material.
By adopting the technical scheme, the cable core is prevented from heating when being electrified, so that the cable is prevented from firing.
The utility model further provides that the ceramic mica tape is internally provided with a plurality of cable cores in a separated mode.
By adopting the technical scheme, the cable cores are isolated by utilizing the ceramic mica tape, and mutual interference of the cable cores after being electrified is prevented.
