General purpose, economical audio and control cable for permanent installation in conduit, walls, or ceilings. The conductive elements consist of stranded, bare copper conductors that are insulated with a PVC insulation compound. For added noise rejection and supression, the conductors are shielded with a durable 100% foil/mylar and tinned copper drain wire. The outer jacket is extruded from a low-friction PVC that is easy to install and pull through conduit.
