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-U Wire
H07V-U wire is a flexible, low voltage electrical wire commonly used in industrial, commercial, and residential applications throughout Europe. It features copper conductors insulated with PVC, which provides protection against moisture, mechanical damage, and electrical faults.
Insulated conductor is used for laying in electric - installation tubes, under and on plaster installation in dry rooms and in closed installation conduits. Direct laying in cable guides is not permitted. Also applied for internal wiring of distribution and switching boxes equipment.
