Description
Technical field
The utility model has related to a kind of low noise cable, but the low noise cable of especially a kind of long-term work under 500 degree temperature environments.
Background technology
Under the extraneous factor effects such as bending, vibration, impact, variations in temperature, cable itself will produce a certain amount of electrostatic signal (or claim the construction of cable noise), usually construction of cable noise will be referred to as low noise cable less than the cable of 5mV.Tiny signal measurement in a plurality of fields such as industrial measurement and control, medical science, national defence all need be used low noise cable.More common low noise cable has polyethylene insulation low noise cable, F46 insulation low noise cable, the low noise cable of anti-irradiation, low electric capacity low noise cable, watertight low noise cable etc. at present, but lacks the low noise cable of high temperature resistant grade.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-temperature resistant low-noise cable, by the selection of structure and material, can long-term work under hot environment, and noise is low during work.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of high-temperature resistant low-noise cable, comprise at least one stranded conductor, described stranded conductor all is wrapped in the total screen, described per share stranded conductor all is enclosed with semiconductive internal shield, insulating barrier, semiconductive outer shielding layer and sub-shield outward successively, and described total screen also is enclosed with outer jacket outward.
Aforesaid high-temperature resistant low-noise cable is characterized in that: described semiconductive internal shield and semiconductive outer shielding layer are extrusion type semiconductive ceramic SiClx quality of rubber materials, and described insulating barrier and outer jacket are extrusion type ceramic silicon rubber material.
Aforesaid high-temperature resistant low-noise cable is characterized in that: described stranded conductor is nickel-clad copper or pure nickel wire is stranded forms.
Aforesaid high-temperature resistant low-noise cable is characterized in that: described sub-shield and formed by the braiding of nickel-clad copper or pure nickel wire high-tension, and the diameter of described nickel-clad copper or pure nickel wire is 0.08mm-0.2mm, count is greater than 80%.
Aforesaid high-temperature resistant low-noise cable is characterized in that: described total screen is formed by nickel-clad copper or pure nickel wire braiding.
Aforesaid high-temperature resistant low-noise cable is characterized in that: the thickness of described semiconductive internal shield, insulating barrier, semiconductive outer shielding layer is 0.2mm-1.5mm.
The beneficial effects of the utility model are: by adopting at least one nickel-clad copper or pure nickel stranded conductor, the inside and outside screen of extrusion type semiconductive ceramic SiClx rubber, extrusion type ceramic silicone rubber insulation layer, and nickel-clad copper or pure nickel wire woven separated-shielding layer, ad hoc structure and the materials such as extrusion type ceramic silicon rubber outer jacket make cable of the present utility model have following advantage:
1, long-term nominal operation temperature range is :-60～500 ℃;
2, satisfy B level fire-resisting cable requirement among the standard GB12666;
3, when 500 ℃ and following temperature, the structureborne noise≤5mV of cable;
4, cable is soft before high temperature burns candle, and it is convenient to lay and install.
Description of drawings
Fig. 1 is the structural representation of the utility model high-temperature resistant low-noise cable.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of high-temperature resistant low-noise cable, comprise at least one stranded conductor 1, described stranded conductor 1 all is wrapped in the total screen 6, the described per share stranded conductor 1 outer semiconductive internal shield 2 that all is enclosed with successively, insulating barrier 3, semiconductive outer shielding layer 4 and sub-shield 5, described total screen 6 outer outer jackets 7 that also are enclosed with, described semiconductive internal shield 2 and semiconductive outer shielding layer 4 are extrusion type semiconductive ceramic SiClx quality of rubber materials, described insulating barrier 3 and outer jacket 7 are extrusion type ceramic silicon rubber material, utilize the different qualities of ceramic silicon rubber when high low temperature, make cable that firm structure can high temperature resistantly be arranged again, when 500 ℃ of high temperature, the semi-conductive layer of cable, insulating barrier is complete ceramic all, and the cable of this moment is heatproof but also firm structure is arranged not only, also keeps electric property, thereby the measuring junction of having realized cable has the characteristic of high-temperature resistant low-noise, the instrument link of cable has also satisfied the low noise requirement simultaneously, and has more flexibility, the convenient use.
And ceramic silicon rubber is directly used in the internal shield 2 of cable and outer shielding layer 4 semi-conductive layer, insulating barrier 3, outer jacket 7 extrude production, not only production technology is simple, every process conditions are easily transferred easily control, and production cost is also relatively cheap.
Stranded conductor 1 is closed or stranded forming by nickel-clad copper or pure nickel material bundle, makes it to become the multiply core, has guaranteed that stranded conductor 1 has corresponding pliability and rounding property.
