SYV75-2-2*4多芯同轴电缆
SYV75-2-2 * 4 multi-core coaxial cable
视频线顾名思义是用来传输视频信号的,是用来传输视频基带模拟信号的一种同轴电缆视频线一般有75欧姆和50欧姆两个阻抗,还可以按照粗细分为-3,-5,-7,-9等型号
Video cable, as the name suggests, is a coaxial cable used to transmit video signals and analog baseband signals. Video cables generally have two impedances of 75 ohms and 50 ohms, and can also be classified into models such as -3, -5, -7, and -9 according to thickness
视频线又根据材质的不同分为SYV和SYWV两种SYV
Video cables are divided into two types, SYV and SYWV, based on their different materials
指实心聚乙烯绝缘的同轴电缆,国标代号是射频电缆——又叫“视频电缆”
Refers to solid polyethylene insulated coaxial cables, with the national standard code being RF cables - also known as "video cables"
一般所指的视频线为电视有线,也可用作安防领域的监控摄像头用线。
The video cable generally refers to television cable, which can also be used as a surveillance camera cable in the security field.
下面是 一般视频线的参数
The following are the parameters of a general video cable
75代表阻抗性,后面的3和5代表它的绝缘外径(3mm/5mm)
75 represents impedance, and the following 3 and 5 represent its insulation outer diameter (3mm/5mm)
SYV中S---同轴射频电缆,Y---聚乙烯,V---聚氯乙烯.
