The purpose of this utility model is: for problems of the prior art, provide that a kind of low decay, loss are little, high-low temperature resistant, advantages of good shielding performance, flexibility is good, volume is little, lightweight, and there is the super soft high temperature resistant radio frequency cable of good resistance to bend(ing) and electric property.
The purpose of this utility model realizes by following technical proposals: a kind of super soft high temperature resistant radio frequency cable, comprise inner wire, the insulating barrier that the expanded microporous polytetra fluoroethylene-EPTEE that is coated on inner wire outer surface is material, surface of insulating layer is being coated screen, screen comprises silver-plated copper strips lapping layer and silver-plated copper single line braid, is being coated the restrictive coating that polytetrafluoroethylene is material on the surface of screen.
Further, inner wire is silver-plated copper single line bundle.
Further, inner wire forms or closes, twists and form again with fine pith bundle by the soft thin diameter silver-plated copper single line of employing multiply is stranded, and bundle twists and twist again employing processing in the same way.
Further, insulating barrier is for adopting expanded microporous polytetra fluoroethylene-EPTEE film once wrapped through multilayer, and taping head is 4 ~ 10.
Further, the copper strips lapping layer of screen is wrapped in the surface of insulating barrier, and the silver-plated copper single line braid of screen is on copper strips lapping layer surface.
Further, restrictive coating is by adopting teflin tape through wrapped processing.
The beneficial effects of the utility model:
(1) inner wire is that the softer thin diameter silver-plated copper single line strands of employing forms, or closes, twists and form again with fine pith bundle, and bundle twists and twist again employing processing in the same way, can improve the flexibility of cable.Insulating barrier adopts expanded microporous polytetra fluoroethylene-EPTEE film through the accurate lapping equipment multilayer of bull wrapped processing once, the characteristics such as expanded microporous polytetra fluoroethylene-EPTEE film wherein has porosity high (can up to more than 90%), soft, density is little, dielectric constant is little, can reduce dielectric loss and the transmission attenuation of cable, improve the stability of signal of telecommunication cable transmission under high low temperature and broadband state.Screen adopts two kinds of forms of the wrapped and silver-plated copper single line of silver-plated copper strips braiding, and stability and the consistency of good shielding properties and signal transmission is provided.Restrictive coating adopts wrapped polytetrafluoroethylene film to process, and makes cable have heat-resisting, cold-resistant, acid and alkali-resistance, corrosion-resistant, flexibility and the performance such as anti-aging.
(2) these materials that the utility model is selected, can guarantee that cable has the characteristics such as decay is low, loss is little, high-low temperature resistant, shielding properties is high, flexibility good, volume is little, lightweight, electric property is stable, can repeated flex change shape and do not affect the serviceability of cable.
