Description

The high-property transmission line

Technical field

The utility model relates to the transmission line that a kind of main use is used at industrial circles such as electronics, communication, naval vessels, especially a kind of in aircraft such as Aeronautics and Astronautics and airborne equipment thereof signal and the transmission of energy in the transmission line that uses.

Background technology

At present, the transmission line that Aeronautics and Astronautics is used has mainly adopted polytetrafluoroethylene or perfluoroethylene-propylene insulated conductor, that this wire insulation extrudes is thick, volume big, Heavy Weight and after standing the outer space high-energy electron irradiation the easy cracking of insulating barrier aging, safety and reliability are poor.Development along with the Aeronautics and Astronautics technology, requirement to the security performance of cabling system in the aircraft, anti-irradiation and indexs such as insulation property and volume weight is more and more higher, and existing polytetrafluoroethylene or perfluoroethylene-propylene insulated conductor have been difficult to satisfy the requirement that Aerospace Products develops to miniaturization, lightweight, high reliability direction.

Summary of the invention

In order to solve the problems referred to above that prior art exists, the utility model provides little, in light weight, the anti-irradiation of the needed volume of a kind of Aeronautics and Astronautics, the high-property transmission line that reliability is high.

The purpose of this utility model can reach by following measure:

A kind of high-property transmission line, it is characterized in that it comprise some strand by the multiply flexible conductor with the stranded conductor wire core that forms 1 monomer of core formula, outside per share conductor wire core 1 monomer, all closely wrap up cross-linked ethylene tetrafluoroethene insulating barrier 2 and constitute the transmission line primary traverse, outside some transmission line primary traverses, closely be enclosed with woven shield 3 or/and cross-linked ethylene tetrafluoroethene sheath 4.

High-property transmission line of the present utility model by multiply (can be 2～10 strands) conductor wire core 1 monomer and outside it close parcel cross-linked ethylene tetrafluoroethene insulating barrier 2 constitute multiply (can be 2～10 strands) transmission line primary traverses, at the outer woven shield 3 that closely is enclosed with of multiply (can be 2～10 strands) transmission line primary traverse; As preferably, outside woven shield 3, also closely be enclosed with cross-linked ethylene tetrafluoroethene sheath 4.

High-property transmission line of the present utility model by multiply (can be 2～10 strands) conductor wire core 1 monomer and outside it close parcel cross-linked ethylene tetrafluoroethene insulating barrier 2 constitute multiply (can be 2～10 strands) transmission line primary traverses, at the outer cross-linked ethylene tetrafluoroethene sheath 4 that closely is enclosed with of multiply (can be 2～10 strands) transmission line primary traverse.

The beneficial effects of the utility model:

(1) external diameter is little, in light weight: inner wire has adopted with core formula strands, and lay configuration is stable, tight, makes the inner conductor outer diameter of same cross-sectional reduce many; Insulating barrier has adopted cross-linked ethylene TFE copolymer material, and the ultra-thin and light specific gravity of insulation thickness makes this product reduce 20% than other product external diameters, and weight saving is more than 20%.

(2) anti-irradiation: owing to adopted the cross-linking type material, make transmission line that good fluorine stability be arranged, can resist the high ionization radiation of outer space, be exposed to 10 ¹²Still can operate as normal in the dosage of Mrad.

(3) safe and reliable: this product has very strong anti-resistance to vertical incision and friction, and the insulating barrier anti-cracking performance is very excellent.

(4) high flame retardant: this product has fire-retardant not flame-retarding power, and oxygen index is greater than 40.

(5) high-low temperature resistant: can use under-65 ℃～+ 200 ℃ conditions for a long time, the short time serviceability temperature can reach more than 280 ℃, and can be by continuing 300 ℃ of 7 hours accelerated aging tests.
