●線芯導(dǎo)體為4N無氧銅絞束而成，抗氧化，訊號導(dǎo)通率高，衰減小。
●此型號線適用傳輸?shù)皖l小信號用線連接，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℃)
●此型號的四芯結(jié)構(gòu)型線可用二二對角兩芯相接(見圖示)法連接，此時(shí)其屏蔽噪音效果更佳，,測定噪聲電并只有兩芯麥克風(fēng)電纜的1/10。
●The Cable has stranded 4Noxygen-fre copperwire asthe core conductor,which resistsoxidation,ensureshigh transmission ate and low attenuation.
●Such cablecan be used forthetransmission of lowfrequency signals,when they are usuall called microphone cables.The protective sheaths are made ofelastic lyvinyl(PVC)in bright colors which are soft,distortion endure,and hard to go brittle.(brittle temperature:-30℃
●The fourcoresare aranged he way which the grap belowshows,whenthey can be best shielded from noises.Noise calibrationofsuch cablesis only 110of hat of two-core microphone cables.
