Abstract
The invention discloses a high-temperature resistant twisted-pair cable which is formed by twisting of two insulated wire cores through a pair twister, wherein each insulated wire core comprises a conductor and a silicon rubber insulating layer extruded outside the conductor; contact surfaces of silicon rubber insulating layers of the insulated wire cores are extruded and connected together. According to the invention, the insulating layers adopt a silicon rubber material structure, and have high-temperature resistant performance, so that start-up of an alarming device can be effectively ensured in case of fire, as a result, safe start-up of a fire extinguishing system is ensured, and people's lives and property are further ensured.
Description
Technical field
The present invention relates to the electric wire field, specifically refer to a kind of high temperature resistant twisted-pair feeder.
Background technology
Twisted-pair feeder plays an important role in the modernization life, the more detector lines that still is used for the fire-fighting automatic fire alarm system.Fire fire-fighting automatic alarm system; be to protect the life property; to be the smog of breaking out of fire or temperature by equipment sense cigarette or temperature-sensitive sensed principle begins to report to the police, and the warning system that also linked simultaneously starts fire extinguishing system, just indirectly the reduction of property life and property loss.Existing twisted-pair feeder often all is to extrude one deck polyvinyl chloride insulation in the stranded conductor outside to constitute insulated wire cores, and then insulated wire cores is carried out pair twist formation twisted-pair feeder.And the insulating material that twisted-pair feeder adopts in the prior art is pvc material, and its temperature resistant grade is low, and 80～85 ℃ begin to soften, and 130 ℃ become the viscoelastic attitude, and 160～180 ℃ begin to change into viscous state.Though can touch alarm activation immediately when fire takes place, the temperature resistant grade of polyvinyl chloride is difficult to effectively ensure the fire extinguishing system clean boot when big fire burns.
Along with the continuous development of all kinds of buildings, construction scope is increasing, and level is more and more higher, and the standard of building is also more and more higher.Newly-built all kinds of buildings all possess characteristics such as personnel are intensive, equipment is advanced, function is many, decoration is luxurious, and therefore, possessing perfect automatic fire alarm and the automatic fire extinguishing system of a cover has become indispensable important component part in the modern life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high temperature resistant twisted-pair feeder, effectively ensures clean boot fire extinguishing system when fire takes place, thereby reduces people's life and property loss.
A kind of high temperature resistant twisted-pair feeder of the present invention thoroughly does away with the edge core by two and forms by pair twister is stranded; Insulated wire cores is by conductor and be extruded in the outer silicone rubber insulation layer of conductor and constitute; Described two contact-making surfaces that thoroughly do away with edge core silicone rubber insulation layer extrude and link together.
Further improve, described conductor is by many stranded the forming of oxygen-free copper monofilament.
Beneficial effect of the present invention is:
Compared with prior art, insulating barrier of the present invention adopts the silicon rubber material-structure, has resistance and high temperature resistance property, when breaking out of fire, can effectively ensure alarm activation, thereby ensure the clean boot of fire extinguishing system, make people's life and property that guarantee also arranged.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of high temperature resistant twisted-pair feeder of the present invention thoroughly does away with the edge core by two and forms by pair twister is stranded; Insulated wire cores is by conductor 1 and be extruded in the outer silicone rubber insulation layer 2 of conductor 1 and constitute; Described two contact-making surfaces that thoroughly do away with the silicone rubber insulation layer 2 of edge core extrude and link together.
The concrete application approach of the present invention is a lot, and the above only is preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
Claims (2)
1. a high temperature resistant twisted-pair feeder thoroughly does away with the edge core by two and forms by pair twister is stranded; It is characterized in that insulated wire cores is by conductor (1) and be extruded in outer silicone rubber insulation layer (2) formation of conductor (1); Described two contact-making surfaces that thoroughly do away with the silicone rubber insulation layer (2) of edge core extrude and link together.
