Wire that has a core composed of many thin copper strands woven together and surrounded by insulation. Stranded conductor wire is generally used for drop cables between computers and wall plates and for patch cables connecting patch panels with hubs and switches. Stranded conductor wire has more attenuation than solid conductor wire and should be used only for short cable runs.
Stranded conductor wire is more durable and reliable than solid conductor wire because it can be bent numerous times without fracturing or breaking, and because damage to the wire has less impact on the surface area of the wire and hence on its capacity to carry alternating current.
Stranded wire comes in two basic configuration types:
