Wires intended use
PV3, PV3ng-LS
Wires are intended for permanent laying within lighting and power networks, as well as for installation of electrical equipment, machines, mechanisms and machining units designed for up to 450 V nominal voltage (up to 450/750 V for networks) and up to 400 Hz frequency or up to 1000 V DC voltage.
Used for installation of electric circuit sections subject to cord bends. Used in all spheres of production and industry as well as for wiring installation. For outdoor wiring it is recommended to use trays, ducts and cable troughs, which protect cords from mechanical damage and ultraviolet radiation.
