The Teflon microporous film used for the telecommunication cable has the advantages of being good in electrical insulating performance and high-frequency performance, voltage-resisting, high-temperature-resisting, low-temperature-resisting and ageing-resisting, particularly has a very low permittivity and a dielectric loss angle tangent value, is capable of being not affected by change of temperature and frequencies, effectively reducing transmission attenuation and loss characteristics of signals, and improving transmission rate of the signals greatly, in addition, a manufactured communication electric cable is good in flexibility, good in humidity-resistance performance, and capable of being used for a long time period in the temperature range of -65 DEG C to 260 DEG C. The Teflon microporous film used for the telecommunication cable is suitable for communication cbale applications.
Description
Technical field
The present invention relates to a kind of telecommunication cable, particularly relate to a kind of telecommunication cable microporous teflon membran.
Background technology
The insulating barrier that traditional telecommunication cable often adopts mostly is tubular body greatly; reason owing to shape and material; in actual use; usually can occur wearing out, not corrosion-resistant, non-uniform temperature; easily produce the crack; make telecommunication cable meet with signal attenuation simultaneously, through-put power descends, and has had a strong impact on the transmission of signal system.Along with the development of telecommunications, the demand of telecommunication cable is constantly soaring, and also more and more higher to the requirement of telecommunication cable, and for this reason, the supporting new product that must continually develop telecommunication cable is with immediately following the market paces, and satisfies the demands.
