SYV75-2-2*4多芯同軸電纜
SYV75-2-2 * 4 multi-core coaxial cable
視頻線顧名思義是用來傳輸視頻信號(hào)的，是用來傳輸視頻基帶模擬信號(hào)的一種同軸電纜視頻線一般有75歐姆和50歐姆兩個(gè)阻抗，還可以按照粗細(xì)分為-3，-5，-7，-9等型號(hào)
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
視頻線又根據(jù)材質(zhì)的不同分為SYV和SYWV兩種SYV
Video cables are divided into two types, SYV and SYWV, based on their different materials
指實(shí)心聚乙烯絕緣的同軸電纜，國標(biāo)代號(hào)是射頻電纜——又叫“視頻電纜”
Refers to solid polyethylene insulated coaxial cables, with the national standard code being RF cables - also known as "video cables"
一般所指的視頻線為電視有線，也可用作安防領(lǐng)域的監(jiān)控?cái)z像頭用線。
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 一般視頻線的參數(shù)
The following are the parameters of a general video cable
75代表阻抗性,后面的3和5代表它的絕緣外徑(3mm/5mm)
75 represents impedance, and the following 3 and 5 represent its insulation outer diameter (3mm/5mm)
SYV中S---同軸射頻電纜,Y---聚乙烯,V---聚氯乙烯.
S-coaxial RF cable in SYV, Y-polyethylene, V-polyvinyl chloride
SYV75-3傳輸在300米之內(nèi)效果好.

75-9 transmission distance 1000-1500 meters
75-12傳輸距離 2000----3500米
75-12 transmission distance 2000-3500 meters
SYWV
SYWV
sywv 指聚乙烯物理發(fā)泡絕緣的同軸電纜，國標(biāo)代號(hào)是射頻電纜
Sywv refers to coaxial cables with polyethylene physical foam insulation, and the national standard code is RF cables
