●線芯導(dǎo)體為4N無(wú)氧銅絞束而成,抗氧化,訊號(hào)導(dǎo)通率高,衰減小。
●此型號(hào)線適用傳輸?shù)皖l小信號(hào)用線連接,俗稱話筒線,外護(hù)套為彈性體聚氯乙烯,手感柔軟,色彩鮮艷,耐扭曲,不脆化。(低溫沖擊脆化溫度可達(dá)-30℃)
●此型號(hào)的四芯結(jié)構(gòu)型線可用二二對(duì)角兩芯相接(見圖示)法連接,此時(shí)其屏蔽噪音效果更佳,,測(cè)定噪聲電并只有兩芯麥克風(fēng)電纜的1/10。
●The Cable has stranded 4Noxygen-fre copper wire asthe core conductor,which resists oxidation,ensures high transmision rate and low attenuation.
●Such cable can be usedforthe transmission of lowfrequency signals,when they are usuall called microphone cables.The protective sheaths are made ofelastic polyvinyl(PVC)in bright colors which are soft,distortion endure,and hard to go brittle.(brittle temperature:-30℃)
othefour cores are aranged the way which the graph below shows,henthey can be best shieided fromnoises.Noise calibrationofsuch cablesis only 110 of hat
of two-core microphone cables.
