Single Core Flexible Wire is a single piece of metal wire that is typically made of copper or aluminium with insulation around it. These can be different gauges as the size of the wire increases, and the flexibility will generally decrease. Single Core Flexible Wire is used in low voltage signals, control panels, and battery cables that are highly flexible and have high Di-electric strength. These are flexible cables that are designed in such a way that comes in use for internal wiring in power and control panels, relay and instrumentation panels.
