The novel fire-resistant compensating lead wire has high temperature-resisting performance and high fireproof performance and has a low-capacitance low-inductance stable signal transmission function.
Description
Technical field
The utility model belongs to the electric wire field, relates to a kind of Novel fire-resistant compensating wire.
Background technology
Connect in the transmission of the hot thermocouple electrical effect of the industrial and mining enterprises such as electric power, metallurgy, chemical industry etc. at present and use compensation lead of thermocouple, basically adopt traditional polyvinyl chloride insulation.This wire has the superior electrical performances such as dielectric constant is little, dielectric loss is little, insulation resistance is large as insulating material, so wire has low electric capacity, inductance and stablizes good transmission performance because of employing.But along with some problems that are widely used of this cable also occur thereupon, be used for connecting the compensating wire of thermocouple, its Main Function is the cold junction that extends the multiple spot focus utmost point and mobile thermocouple, connect and compose multi-point temperature measurement system with Displaying Meter, the mechanical and physical performances such as the insulation of common compensating wire and sheath make the serviceability of wire descend under the impact that is subjected to high temperature, oxidation and impulsive force, cause transmission of electric signals that deviation is arranged, can not satisfy the needs of accurate transmission.
The utility model content
Use the problem that exists in some particular surroundings occasions in order to overcome existing common compensating wire, the purpose of this utility model is to provide a kind of and has high-temperature resistant performance and high fire protecting performance, and has the Novel fire-resistant compensating wire of the stabilization signal transfer function of low electric capacity, low inductance.
Scheme of the present utility model is as follows: a kind of Novel fire-resistant compensating wire, and its insulated wire cores from-inner-to-outer is made of alloy conductor, insulating barrier, and positive and negative insulated wire cores is by doubling group unit, and doubling group unit is outside equipped with belting layer and screen, and external sheath layer forms.
Described insulating layer material adopts ceramic silicon rubber insulation material to make.
Described belting layer material is the flame-proof glass fibre rope.
Described polymeric barrier layer materials is the proof copper-wire braided screen.
Described restrictive coating material is ceramic silicone rubber jacket material.
The beneficial effects of the utility model:
1, the insulating material of compensating wire adopts new ceramics SiClx rubber-covered material, and this material is a kind of organosilicon macromolecule composite material.This material is compared with common material, and is high temperature resistant higher with fire resistance, guarantees that cable has stable transfer function.
2, the sheath material of cable adopts ceramic silicone rubber jacket material equally.This material composition is equal to the various compositions of Insulation Material, has taken into full account the Halogen of cable, low cigarette, fire resistance.Not only have good fire resistance, and when burning the amount of being fuming low, on every side personnel and equipment without illeffects.
3, the auxiliary band material of cable is to adopt the combustion-proof glass fiber material, not only has good fire resistance, and all is not halogen-containing environment-friendly materials.The utility model provides a kind of novel compensating wire that fire-resistant, high temperature resistant, acid and alkali-resistance, chemical-resistant reagent, ageing-resistant performance have stable signal transfer functions simultaneously that has.

Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of Novel fire-resistant compensating wire, it is made of conductor 1, insulating barrier 2 the insulated wire cores from-inner-to-outer, and positive and negative insulated wire cores is by doubling group unit, and doubling group unit is outside equipped with belting layer 3 and screen 4, and external sheath layer 5 forms.
Shown in Figure 1, the described a kind of Novel fire-resistant compensating wire of present embodiment, conductor 1 adopts the multiply soft copper tow compositing conducting core of the 5th class formation, the following step of conductor production process: wire drawing-annealing-synnema, the form that conductor adopts bundle to close, wherein 1mm
2 The monofilament maximum gauge is as 0.21mm in the lower conductor, 1.5-2.5 mm
2 The monofilament maximum gauge is 0.26mm in the conductor.Insulating barrier 2 adopts ceramic silicon rubber insulation material, and its production process is finished the production of SJ85 extruder, adopts plsitive mold to extrude, and drying tunnel temperature is controlled at 260 ± 20 ℃.Belting layer 3 adopts the halogen-free flame-retardant glass fiber band, and production form adopts overlapping wrapped, and the rate of putting up is not less than 15%, and Main Function is tightened the line group.The production process of shielding layer of copper wires 4 is finished at 16 ingot braiding machines, and the braiding angle general control is controlled at count more than 80% by regulating braiding angle or lay of braiding between 30～60 degree.Restrictive coating 5 adopts ceramic silicone rubber jacket layer, also adopts plsitive mold to extrude, and drying tunnel temperature is controlled at 260 ± 20 ℃.In the XJ85 extruder, use.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
