Stranded Bare Coppers is flexible and easily shaped, formed, welded and soldered. It is used in overhead transmission and distribution systems and for grounding grid systems. It has PVC or non-floating PVC outer jacket. It is suitable for use in CCTV monitoring, conduction and unidirectional control systems, including various high-frequency equipment and various A/V devices. Wire and cable is made with solid bare copper conductors which is not as flexible as made with stranded copper conductors. The decrease in flexibility is made up for with the reduced expense of solid bare copper alarm cable. Most low voltage alarm systems use a small gauge size wire and the small loss of cable flexibility.
