Technical field
This utility model relates to a kind of cable insulation extrusion die, particularly relates to a kind of cable abnormity insulating barrier high temperature extrusion die.
Background technology
Radio-frequency cable is the cable of electromagnetic energy in transmission radio-frequency region, and radio-frequency cable is indispensable element in various radio communications system and electronic equipment, is widely applied at aspects such as radio communication and broadcast, TV, radar, navigation, computer and instrument.
Radio frequency coaxial-cable has referred to two concentric conductors, and conductor and screen layer share the cable in same axle center.RF coaxial cable insulation cable material uses physical blowing polyethylene isolation copper conductors composition, is another layer of ring shaped conductor i.e. outer conductor in the outside of nexine insulant, and outer conductor (tissue screen layer) uses copper strips molding, welds, pricks stricture of vagina；Or employing aluminium pipe structure；Or employing braiding structure, the most whole cable is encased by the sheath of pvc material.
The physical foaming material that insulating barrier is solid of the radio frequency coaxial-cable used in industry at present or other insulator.The insulator using solid construction certainly exists the problem that dielectric constant is high so that signal is decayed greatly in transmitting procedure, and through-put power is difficult to improve, and transfer rate is low, and the consumption of material is big, and product weight is big, and cost is high, and non-refractory；Use perfluoroethylene-propylene (FEP) or tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer perfluoroethylene-propylene (PFA) expanded material as insulating barrier, although the problem that hot environment can be solved, the most solid, still suffer from the problem that above-mentioned dielectric constant height brings, and the cost of FEP and PFA material is higher.
Find through long-term production process, the bottleneck problem improving radio frequency coaxial-cable performance is the dielectric constant of insulating barrier, through long-term test, have developed employing FEP and PFA expanded material and make hollow insulation system radio frequency coaxial-cable, reduce the dielectric constant of insulating barrier, dielectric constant, between 1.3 to 1.65, saves material, solves above-mentioned problem.
Our company proposes application with regard to above-mentioned hollow insulation system radio frequency coaxial-cable, meanwhile, and contents of which patents to be realized, in addition it is also necessary to a set of cable abnormity insulating barrier high temperature extrusion die adapted therewith, it is achieved the production of this insulating barrier.
