●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。

●此型号线适用传输低频小信号用线连接,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 andlow atenuation.

●Such cables are usedforthetransmision oflow frequency signals,Spiral shieldis even softer than braid shield,The elastic protective jackets are made of polyvinyl chloride in bright colors which are soft,distortion endure,and hard to go brittle.(brittle temperature:-30℃
