MC~2是应用电视和CATV大型系统工程用的干线和分支线电视电缆,用于传送电视射频信号和视频信号,是目前美国最新的低损耗高强度电缆,国内也有相类似的干线电缆生产。一、MC~2名称由来“MC~2”纯属商业名称,它源于爱因斯坦的相对论,爱氏提出物体的能量和质量之间有着严格的正比关系,即E=MC~2,这就是有名的质能方程,美国Trilogy通信公司就用MC~2作为它们生产的竹节式同轴电缆的商品名称。MC~2还有另一种解说,即同轴电缆英文是Coaxial Cable,两个词的第一字母均为C,故谓C的平方;而M即Modern的第一个字母,有现代化先进之意。二、MC~2电缆的发展最早的射频电缆绝缘结构是实芯聚乙烯,这种结构成本高,介电常数大,电气性能就显得差。但事物总是一分为二的,除了上述的缺点外,因为是实芯电缆,
MC ~ 2 is a trunk and branch cable used for large-scale systems engineering of television and CATV. It is used to transmit TV RF signals and video signals. It is the latest low-loss and high-strength cable in the United States and has similar trunk cable production in China. First, the origin of MC ~ 2 “MC ~ 2” is purely a commercial name, it is derived from Einstein’s theory of relativity, Ai’s proposed object has a strict proportional relationship between energy and quality, that is, E = MC ~ 2, which Is a well-known mass-energy equation, the United States Trilogy Communications MC ~ 2 on the use of them as the production of bamboo coaxial cable brand name. MC ~ 2 There is another explanation, that Coaxial Cable in English is Coaxial Cable, the first letter of the two words are C, so that the square C; and M that Modern is the first letter of the modern advanced meaning. Second, the development of MC ~ 2 cable Earliest RF cable insulation structure is solid core polyethylene, this structure is high cost, high dielectric constant, the electrical performance is poor. But things are always divided into two, in addition to the above shortcomings, because it is a solid core cable,
