Abstract
The utility model relates to a coaxial cable insulated by winding polytetrafluoroethylene circular tubes, which is used for high-temperature resistant, high-power and remote communication transmission. The cable is formed by closely compositing an inner conductor (1), an insulator (2), an outer conductor (3) and a jacket (4) from inside to outside sequentially; the inner conductor (1) is one silver plated copper wire or a plurality of silver plated copper wires or one copper clad aluminium wire or a plurality of copper clad aluminium wires; the insulator (2) is formed by a plurality of polytetrafluoroethylene hollow circular tubes which are wound on the inner conductor (1), so as to form a winding insulator. The diameter of each hollow tube can reach more than 50mm, and the diameter of the coaxial cable insulated by winding polytetrafluoroethylene circular tubes can reach more than 150mm, and the insulator can be made thicker, so as to be suitable for high-power transmission.
Description
(1) technical field
It is low and can make large diameter coaxial cable that the utility model relates to a kind of insulative dielectric constant, be generally used for high temperature resistant, high-power, communication transmission at a distance.
(2) background technology
The teflon insulation of coaxial cable is realized with wrapped microporous barrier always at present, but just very difficult around arriving more than the diameter 15mm.And along with the increase in demand of powerful device, high performance transmission cable is essential.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can accomplish insulator very slightly, and the polytetrafluoroethylene pipe that is fit to powerful transmission twines insulation coaxial cable.
The purpose of this utility model is achieved in that a kind of polytetrafluoroethylene pipe twines insulation coaxial cable, described cable from the inside to the outside successively by inner wire, insulator, outer conductor and sheath totally four layers closely be composited, described inner wire is single or many silver-coated copper wires or copper-clad aluminum conductor; Described insulator is made up of many polytetrafluoroethylene hollow circular-tubes, and many polytetrafluoroethylene hollow circular-tubes twine in the conductor, forms and twines insulator.
The beneficial effects of the utility model are:
The utility model polytetrafluoroethylene pipe twines insulation coaxial cable and has bigger advantage than similar teflon insulation product, twining insulator is to be formed by many hollow pipe parcel inner wires, the hollow pipe diameter can reach more than the 50mm, the polytetrafluoroethylene pipe twines the insulation coaxial cable diameter can be accomplished more than the 150mm, so can accomplish insulator very slightly, be fit to powerful transmission.And insulator is because what use is that winding arrangement also has good pliability, outer course body support force uniformly, and it is maximum that to use power be more than 10 times of conventional polytetrafluoroethylene low-density insulated cable.
(4) description of drawings
Fig. 1 is the Facad structure schematic diagram that the utility model polytetrafluoroethylene pipe twines insulation coaxial cable.
Fig. 2 is the sectional drawing of Fig. 1.
Reference numeral among the figure:
Inner wire 1, insulator 2, outer conductor 3, sheath 4.
(5) embodiment
Referring to Fig. 1～2, Fig. 1 is the Facad structure schematic diagram that the utility model polytetrafluoroethylene pipe twines insulation coaxial cable.Fig. 2 is the sectional drawing of Fig. 1.By Fig. 1 and Fig. 2 as can be seen, the utility model polytetrafluoroethylene pipe twines insulation coaxial cable, from the inside to the outside successively by inner wire 1, insulator 2, outer conductor 3 and sheath 4 totally four layers closely be composited.
Described inner wire 1 is single or many silver-coated copper wires or copper-clad aluminum conductor.
Described insulator 2 materials are polytetrafluoroethylene, are earlier polytetrafluoroethylene to be processed into hollow circular-tube, then many polytetrafluoroethylene hollow circular-tubes are wound in uniformly the winding insulator on the inner wire 1.
Described outer conductor 3 can adopt the braiding of silver-plated circular copper wire or adopt silver-plated flat type copper wire braiding or adopt vertical copper-clad to mould composite membrane or adopt vertical alclad to mould the paper tinsel composite membrane or the ripple copper pipe is realized;
Described sheath 4 is according to environment for use and requires difference can adopt poly-perfluor one propylene or polyurethane or polyethylene or polyvinyl chloride.
