16mm Bare Copper Earth Wire
Application field
Stranded 16mm2 stranded flexible round copper stranded wire is generally used for the production of Class 5, class 6 cable conductors.
Class 5 cable is a kind of multimedia cable that transmits data, voice and other information and communication services. It is widely used in broadband access projects such as broadband user's resident network. Its quality is directly related to the transmission quality of information and communication
Class 6 conductors are extra soft conductors, used for special moving cables, such as welding machine taps.
Among them, Class 5 conductors and class 6 conductors are further divided into tinned copper conductors and untinned copper conductors. The most common conductor material is copper. We all know that copper has bare copper (called brass, red copper), tinned copper, silver-plated copper wire, etc., which are essentially copper, but the surface is plated with other substances.
Class 5 conductors are general soft conductors, that is, conductors used as general moving cables.
Class 6 conductors are extra soft conductors, used for special moving cables, such as welding machine taps.
Physical property
Specification structure of Class 5 and Class 6 conductorsThe softness of class 6 conductors is better than that of class 5 conductors, and is generally used for cables with high softness requirements.
