●线芯导体为4N无氧铜绞束而成，抗氧化，讯号导通率高，衰减小。

●此型号为麦克风电缆的标准形式。此型号线适用传输低频小信号用线连接，俗称话筒线，缠绕屏蔽相对编织屏蔽更为柔软，外护套为弹性体聚氯乙烯，手感

柔软，色彩鲜艳，耐扭曲，不脆化。(低温冲击脆化温度可达-30℃)

The Cable has stranded 4Noxygen-free copperas the core conductor,which resists oxidation,ensures high transmission rate and low attenuation.

Such cables are usedforthe transmission oflow frequency signals,when they are usuall called microphone cables.Spiral shield is even softr than braid shield, The elastic protectivejackets are made o olyinylchioridein bright colors which are soft,distortion endure,and hard to go britte.(britletemperature:-30℃
