●線芯導(dǎo)體為4N無氧銅絞束而成，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，纏繞屏蔽相對(duì)編織屏蔽更為柔軟，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℃)
●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℃
