Aforesaid superhigh temperature resistant low noise cable is characterized in that: the pure nickel wire high-tension braiding that said pure nickel wire braiding sub-shield employing diameter is 0.08mm-0.25mm forms, and count is greater than 80%.
Aforesaid superhigh temperature resistant low noise cable is characterized in that: said pure nickel wire weaves total screen and closely contacts with each pure nickel wire braiding sub-shield.
The invention has the beneficial effects as follows: through adopting multiply pure nickel stranded conductor, the compound inside and outside screen of semiconductive, composite insulation layer, pure nickel wire braiding sub-shield and total screen; Ad hoc structure and technologies such as compound outer jacket have the flexibility of ordinary silicon rubber cable under the normal temperature, be easy to use and lay; In the time of 1000 ℃, because the design of the special construction of selected materials characteristic and this cable, the cable of this moment is heatproof but also firm structure is arranged not only; Also keep good electric property, thereby realized the high-temperature resistant low-noise characteristic of cable, the different qualities when having made full use of the high low temperature of ceramicization silicon rubber and the high-temperature stability of silicon oxide fibre silk; The measuring junction of having realized this cable satisfies the high-temperature resistant low-noise requirement; The instrument link of cable also satisfies the low noise requirement simultaneously, also has more flexibility, the convenient use.
Make cable of the present invention have following advantage:
1, long-term nominal operation temperature range is :-60～1000 ℃;
2, satisfy B level fire-resisting cable requirement among the standard GB12666;
3, when 1000 ℃ 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 superhigh temperature resistant low noise cable of the present invention.
Embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of superhigh temperature resistant low noise cable; Comprise that multiply all is wrapped in same pure nickel wire and weaves the pure nickel stranded conductor 1 in total screen 10, said pure nickel wire weaves total screen 10 outer compound outer jackets of being made up of the silicon oxide fibre silk braiding outer jacket 11 and first high temperature coating 12 that also wrap up; The said per share pure nickel stranded conductor 1 outer compound internal shield of forming by the first semiconductive ceramic silication rubber layer 2 and the first semiconductive silicon oxide fibre silk braid 3 of semiconductive that all is enclosed with; The compound internal shield of semiconductive is wrapped with the composite insulation layer of being made up of mica lapped insulation layer 4, silicon oxide fibre silk braiding insulating barrier 5 and second high temperature coating 6; Composite insulation layer is wrapped with the compound outer shielding layer of being made up of the second semiconductive ceramic silastic-layer 7 and the second semiconductive silicon oxide fibre silk braid 8 of semiconductive; The compound outer shielding layer of semiconductive is wrapped with pure nickel wire braiding sub-shield 9.
Pure nickel stranded conductor 1 adopts bundle to close or stranded technology, makes it to become the multiply core, guarantees that stranded conductor has corresponding pliability and rounding property, and guarantees that oxidation fusing can not take place conductor in the time of 1000 ℃; Through outside pure nickel stranded conductor 1, wrap up outer 7, the second semiconductive silicon oxide fibre silk braid 8 of the first semiconductive ceramic silastic-layer 2, the first semiconductive silicon oxide fibre silk braid 3, mica lapped insulation layer 4, silicon oxide fibre silk braiding insulating barrier 5, second high temperature coating 6, the second semiconductive ceramic silicon rubber successively, pure nickel wire weaves sub-shield 9; Guaranteed the Stability Analysis of Structures of cable, and the electrostatic signal (also can be referred to as structureborne noise) that cable itself is produced has dropped to minimum.When 500 ℃ of high temperature; The semiconductive ceramic silicon rubber internal shield 2 of cable is potteryization fully; During to 1000 ℃ of superhigh temperature; The composite insulation layer of being made up of mica lapped insulation layer 4, the silicon oxide fibre silk braiding insulating barrier 5 and second high temperature coating 6 still can keep excellent electric characteristics, and under the acting in conjunction of the first semiconductive ceramic silication rubber layer 2, the first semiconductive silicon oxide fibre silk braid 3 and pure nickel stranded conductor 1, cable at this moment is heatproof but also firm structure is arranged not only; Also keep electric property, thereby realized the high-temperature resistant low-noise characteristic of cable.
