Abstract
The invention discloses a fireproof coaxial cable resistant to high temperature. The fireproof coaxial cable is composed of a central conductor, an outer conductor, an insulation layer, a fireproof layer and a protection jacket. An inner crusting layer is arranged between the central conductor and the outer conductor. A galvanized annealed copper alloy wire armor layer is arranged between the insulation layer and the fireproof layer. The insulation layer is an organic silicon belt comprising mica and graphite. The fireproof layer is formed by sequentially and closely arranging a plurality of ceramic fiber fire belts comprising poly (trifluoropropyl) methylsiloxane. The fireproof coaxial cable is good in conductivity, excellent in fatigue resistance and high in ability to resist breakage, is mainly applied to the fields of computers, communication and the like, and is high in anti-jamming ability, high temperature resistance and fire resistance.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of fire resistant coaxial cable.
Background technology
At present, coaxial cable is for various electronic installations and electric device, for example: diagnostic probe and the industrial robot etc. of mobile phone, portable computer, diagnostic ultrasound equipment and endoscope, require cable not only will possess good fatigue durability and anti-broken string ability, but also need to possess higher fire resistant performance and anti-interference.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the fire resistant coaxial cable that good, the anti-broken string ability of a kind of fatigue durability is strong, fire resistant performance is high and anti-interference is excellent.
The present invention takes following technical scheme to realize: a kind of fire resistant coaxial cable, it is made up of center conductor, outer conductor, insulating barrier, fireprotection layer and protective sleeve.Between described center conductor and described outer conductor, be provided with interior skinning cortex, between described insulating barrier and described fireprotection layer, be provided with the zinc-plated annealed copper B alloy wire of one deck armour, described insulating barrier is the organic silicon ribbon that contains mica, graphite, and described fireprotection layer is made up of multiple ceramic fibre fire guards that contain poly-methyl trifluoro propyl siloxanes successively close-packed arrays.
Described center conductor is some strands of zinc-plated Al-Ag alloy wires stranded forming to the right.
The present invention has following beneficial effect in sum: this kind of cable conduction performance is good, and fatigue durability is excellent, and anti-broken string ability is strong, is mainly used in the field such as computer, communication, and antijamming capability is strong, also has higher fire resistant performance simultaneously.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, center conductor; 2, interior skinning cortex; 3, outer conductor; 4, copper strips belting layer; 5, zinc-plated annealing copper wire armour; 6, ultraviolet resistant layer; 7, protective sleeve; 8, tinned copper wire drainage thread.
Embodiment
The object of this invention is to provide the fire resistant coaxial cable that good, the anti-broken string ability of a kind of fatigue durability is strong, fire resistant performance is high and anti-interference is excellent.Be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of fire resistant coaxial cable, it is made up of center conductor, outer conductor, insulating barrier, fireprotection layer and protective sleeve.Between described center conductor and described outer conductor, be provided with interior skinning cortex, between described insulating barrier and described fireprotection layer, be provided with the zinc-plated annealed copper B alloy wire of one deck armour, described insulating barrier is the organic silicon ribbon that contains mica, graphite, and described fireprotection layer is made up of multiple ceramic fibre fire guards that contain poly-methyl trifluoro propyl siloxanes successively close-packed arrays.
Described center conductor is some strands of zinc-plated Al-Ag alloy wires stranded forming to the right.
The permission bending radius of this cable is the outside diameter of cable 10 times; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown, allows to work 3.5h under 200 ℃ of hot environments.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
