Description
Technical Field
The utility model belongs to the technical field of power cable, specifically be a novel fire resisting cable.
Background
With the continuous development of society, the requirements of people on safety protection are continuously improved, and the cable for providing electric power for production and life of people is also regarded as a lot in this respect.
However, ordinary cable on the market can lead to the short circuit because of conflagration or other reasons at present, leads to power transmission then can not continue the operation, seriously influences people's production life, consequently the utility model designs a neotype fire resisting cable in order to solve above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel fire resisting cable to solve among the prior art ordinary cable security problem high, that fire resistance is not good enough.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel fire resisting cable, includes the outer and cable inner core of cable, the outer inside of cable is equipped with the steel band, and the material of steel band is the steel, and the effect is thermal-insulated, the fire prevention, and the steel band tightly twines in the outside of filling layer, the cable inner core includes conductor, first insulation layer, flame retardant coating, second insulating layer, the inside of second insulating layer is equipped with the flame retardant coating, the inside of flame retardant coating is equipped with the first insulation layer, the inside on first insulation layer is equipped with the conductor.
Preferably, a filling layer is arranged between the steel belt and the cable inner core, the filling layer is a flame-retardant glass fiber belt, the flame-retardant glass fiber belt is wound on the cable inner core to tightly wrap the three cable inner cores, and the steel belt is wound and wrapped outside the cable inner core.
Preferably, the first insulating layer is a PVC material, and the PVC material functions to isolate electric current so that the conductor does not leak electricity.
Preferably, the fireproof layer is a glass fiber rope, the glass fiber rope is an elastic glass fiber rope woven by an innovative weaving method, has the performances of fire resistance, corrosion resistance and high strength, and is wrapped on the first insulating layer to play a role in flame retardance.
Preferably, the second insulating layer is made of a PE material, the PE material has the functions of isolating current and preventing electric leakage, no solid is generated after the PE material is burnt to prevent other flame-retardant materials from exerting efficacy, and the second insulating layer is wrapped and fixed with the glass fiber rope.
Preferably, there are three of the cable cores.
Compared with the prior art, the beneficial effects of the utility model are that: through the cable skin, steel band and the fire-retardant glass fiber band of winding on the cable inner core, when making the more fire-resistant of cable, also make the electromagnetic shield nature and the security of cable better, because the melting point of steel band is very high, even consequently the conflagration breaks out, flame that the temperature is not high also lets the cable inner core melt at most, and can not the direct combustion, very big reduction the harm that the conflagration caused, through first insulating layer, second insulating layer and flame retardant coating, there is dual fail-safe when making the cable meet the conflagration, can be more safe and reliable.
Drawings
Fig. 1 is a front sectional view of the present invention.
In the figure: the cable comprises an outer layer of a cable 1, an inner core of the cable 2, a first insulating layer 21, a second insulating layer 22, a fireproof layer 23, a conductor 24, a filling layer 3 and a steel belt 4.
Detailed Description
Referring to fig. 1, a novel fire-resistant cable includes an outer cable layer 1 and an inner cable core 2, a steel belt 4 is disposed inside the outer cable layer 1, the inner cable core 2 includes a conductor 24, a first insulating layer 21, a fireproof layer 23 and a second insulating layer 22, the fireproof layer 23 is disposed inside the second insulating layer 22, the first insulating layer 21 is disposed inside the fireproof layer 23, and the conductor 24 is disposed inside the first insulating layer 21.
Referring to fig. 1, a filling layer 3 is arranged between a steel belt 4 and cable cores 2, the filling layer 3 is a flame-retardant glass fiber belt, the flame-retardant glass fiber belt is wound on the cable cores 2 to tightly wrap the three cable cores 2, and the steel belt 4 is wound and wrapped outside the cable, because the steel belt 4 and the flame-retardant glass fiber belt are difficult to burn, the cable can withstand higher temperature.
Referring to fig. 1, the first insulating layer 21 is made of PVC, the PVC has a function of isolating current so that the conductor 24 does not leak electricity, the fireproof layer 23 is made of glass fiber rope, the glass fiber rope is woven by a special process, the fireproof layer is an elastic glass fiber rope woven by an innovative weaving method, the fireproof layer has fire resistance, corrosion resistance and high strength, and the glass fiber rope is wrapped on the first insulating layer 21 to play a role of flame retardance.
Referring to fig. 1, the second insulating layer 22 is made of PE, and the PE has the functions of isolating current and preventing leakage, and because the PE does not produce solid after burning to block other flame retardant materials from performing, three are wrapped and fixed with glass fiber ropes, and three are cable cores 2.
The working principle of the scheme is as follows: when the conflagration breaing out, filling layer 3 and steel band 4 can play fine flame retardant action, because the melting point of steel band 4 is very high, even consequently, the conflagration breaks out, flame that the temperature is not high also lets cable inner core 2 melt on top more, and can not direct combustion, the very big harm that the conflagration caused that has reduced, and moreover, the fire-retardant glass fiber band of filling layer 3, also difficult burning, the heat conductivity is also not good, and still contain the glass fiber rope in the cable inner core 2, so, under double-deck protection, when the true burning of cable, also can be very big speed of slowing down the burning, guarantee the completeness of cable, strive for the time for the activity of putting out the conflagration or other maintenance people property.
