Abstract
The utility model relates to a cable, more specifically a fireproof cable with high temperature resistance. The utility model is characterized in that a fireproof layer is added between the conductor of a cable core and an insulating layer; the outer protective layer outside the cable core is orderly composed of a glass fiber tape wrapping layer, a braid layer and a polytetrafluoroethylene or poly-perfluoro-ethylene-propylene sheath layer. The approved operating temperature of the utility model is 200 to 250 DEG C in long term. When fire happens, the utility model can provide power normally for 90 minutes. With the characteristics of acid resistance, alkali resistance, fire resistance and high temperature resistance, the utility model is suitable for high-temperature hostile environments and situations requiring fire resistance.
Description
Technical field
The utility model relates to a kind of cable, specifically the fire resistant cable.
Background technology
Fireproof cable and high temperature-resistant cable are two kinds of matured products, common fire-resistant (fire prevention) cable is the cable by the fire resistance test method standard of GB12666.6 (IEC331) cable, when breaking out of fire, promptly more than energy normal power supply 90min under 900-1000 ℃ the flame temperature, to reach the purpose of lifesaving, when general cable use, the highest long-term work temperature of conductor can only reach 90 ℃ at ordinary times.High temperature-resistant cable is that a kind of insulation and sheath all adopt the plastics king--the cable that-fluoroplastics are made, and it can be worked under 200-250 ℃ hot conditions for a long time, but it does not have fire prevention, fire-resistant function, and can not normal power supply when fire takes place.
Summary of the invention
Both high temperature resistant in order to solve simultaneously, fire-resistant, fire safety problem again, the utility model provides a kind of fire resistant cable.
The present invention seeks to be achieved through the following technical solutions:
1, fire resistant cable comprises cable core and outer jacket, and cable core comprises that conductor and polytetrafluoroethylene or perfluoroethylene-propylene insulating barrier is characterized in that:
A, between the conductor of cable core and insulating barrier, set up fireprotection layer;
The outer jacket of B, cable core outside is followed successively by glass fiber tape lapping layer, braid and polytetrafluoroethylene or perfluoroethylene-propylene restrictive coating.
2, described fireprotection layer or be mica tape, or be glass fiber tape.
3, described braid is made up of copper wire and glass fiber braiding.
Advantage applies of the present utility model is aspect following three:
(1), the long-term working temperature that allows of the utility model is 200-250 ℃.
(2), this cable when fire takes place, can normal power supply 90 minutes.
(3), cable of the present utility model has acid and alkali resistance, fire-resistant, high-temperature stability, be applicable to high-temperature severe environment and requirement fireproof occasion arranged.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1, the master core of this cable is made up of conductor 1 and insulating barrier, and insulating barrier comprises fireprotection layer 2 and polytetrafluoroethylene or perfluoroethylene-propylene insulating barrier 3 structures.The material of fireprotection layer 2 is made up of fire-resistant isinglass belt and glass fiber tape, wrapped on conductor 1 as refractory insulating layer, polytetrafluoroethylene or perfluoroethylene-propylene have plastics king's title, make temperature-resistant insulation layer 3.
The outer jacket of cable core outside is followed successively by glass fiber tape lapping layer 4, braid 5 and polytetrafluoroethylene or perfluoroethylene-propylene restrictive coating 6.Braid 5 is made up of copper wire and glass fiber braiding, and is wrapped outside glass fiber tape lapping layer 4, extrudes polytetrafluoroethylene or perfluoroethylene-propylene restrictive coating 6 again outside it.
Other characteristic according to product can increase other structural detail, as anti-interference braiding copper screen or the steel screen of adding, can add steel band or wire armoring as anti-mechanical external force.
Claims (3)
1, fire resistant cable comprises cable core and outer jacket, and cable core comprises that conductor and polytetrafluoroethylene or perfluoroethylene-propylene insulating barrier is characterized in that:
A, between the conductor of cable core and insulating barrier, set up fireprotection layer;
The outer jacket of B, cable core outside is followed successively by glass fiber tape lapping layer, braid and polytetrafluoroethylene or perfluoroethylene-propylene restrictive coating.
2, fire resistant cable according to claim 1 is characterized in that: described fireprotection layer or for mica tape, or be glass fiber tape.
3, fire resistant cable according to claim 1 is characterized in that: described braid is made up of copper wire and glass fiber braiding.
