75 ohm  triaxial cable for video signals in cabinentertainment  
      75-ohm  video cables are designedto minimize emi while providing low-loss transmission of videosignals for security, means of an isolated second 95% coverageshield — the major benefit of a triaxial design, in-flightentertainment and cockpit displays.
used for video signals in cabin entertainment andother air-borne applications, the outer shield is customarilygrounded   in order to provide a bypass for both inducedand electric  field noise currents. thus emi is significantlyreduced.

在实际使用中,cmp线缆在燃烧冒烟解体之前可以忍受高达800℃以上的温度,它比通常无卤线缆最高可承受150℃的温度要高数倍。同时,cmp缆线还有一个显著特点是即使强制使其燃烧,燃烧时产生的烟雾也很少。在大楼火灾中保证人员有良好的视线去逃生,这是极为重要的。
电缆具有优良的机械和电气特性,被用于很多场合,这些场合的温度达到200°c以上,以及零下40°c以下,在很多恶劣的环境下,很多电缆都会受到化学烟雾和液体的侵蚀,众所周知,许多年来一直在电缆行业被用作耐用性的聚合物,它具有优良的介电特性,甚至在升温的情况下,使它更适合于电缆绝缘,铁氟龙绝缘电缆具有阻燃,耐化学侵蚀,防紫外线,以及阻碍潮湿和电晕。
 氟塑料电缆具有很宽的耐高温和耐低温范围,与传统的pvc相比,聚全氟乙烯电缆更是有下列一些优点,它可以在极端天气环境温度下,从-80°c到+200°c的进行安装,减少了电缆的擦伤和拉伤,由于它具有极低的摩擦系数,使其在布线,拉线和穿管时,都是最小可能的造成对护套损伤。这种护套还具有耐各种燃料,耐油,耐溶剂,耐酸,耐化学腐蚀,防紫外线,防水。适合直接预埋,而且,它更是对电缆穿管布线空间的节省。被应用于电力项目的仪器仪表,化工,钢铁厂,军事,航天以及各种其它工业工程。
