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℃
