Electric wires are conductive materials used to carry electrical current between power sources, devices, and systems. They are fundamental to modern electrical systems, providing safe and efficient energy transmission for various residential, commercial, and industrial applications.
Home / Product / Electric Wire / H07V-K Wire
H07V-K wire is a type of low voltage, PVC-insulated cable commonly used in residential, commercial, and industrial electrical installations across Europe. It consists of one or more copper conductors, encased in a flexible PVC insulation that provides excellent protection against moisture, abrasion, and chemical exposure.
Application: For indoor fixed installations in dry locations, in electrical equipment, switchboards and distributors. Should be installed in surface mounted or embedded conduits, for protected fixed installations in or on lighting fittings. Suitable for installations in machines for nominal voltages up to 1.000 V alternating current or up to 750 V to earth direct current. Cannot be used for installations under the wall surface.
