●线芯导体为4N 无氧铜束绞而成，抗氧化，讯号导通率高，衰减小。

●此线为高，低音频传输的理想线材。

●优质聚乙烯护套，耐弯折，抗扭绞，适用工程安装穿管。

●外形圆整紧密，不易受潮，耐低温，不脆化。(低温冲击脆化温度可达-30℃)

●The cables have stranded 4Noxygen-free copper asthe core conductor,which resists oxidation,nsures high 4transmission rate and low attenuation.

●These cables are perfect for the transmission of both high and low frequency signals.

●The protectivejacket is madeofquality polyinylchloride,which has exceptional twist resistance capabilties and can be used for pipe penetrationin engineering installation projects.

●The cable is in circular shape,damp proof and has low brittle temperature.(brittle temperature:-30℃
