電線電纜
SYV50Ω系列實(shí)芯聚乙烯絕緣氯乙烯護(hù)套同軸電纜
SYV50Ωseries solid polyvinyl insulated and PVC jacket coaxial cable
1應(yīng)用:
電視與廣播發(fā)射系統(tǒng)及微波、衛(wèi)星通訊系統(tǒng)、也可以用于電腦網(wǎng)絡(luò)(如以太網(wǎng))的互聯(lián)。居有較高的傳輸頻率和較低的衰減。被廣泛應(yīng)用在衛(wèi)星電視系統(tǒng),單向控制系統(tǒng)及電子器材等較長距離的連接中。
Application: Applicable to TV, broadcast emission system, micro-wave and satellite communication system, also internet (as Ethernet). It has a rather high transmission frequency and low attenuation. It’s broadly applied in long distance of equipment cable in satellite TV system, unilateral control system, electric equipment and etc.
