Building Wire
BVR wire (distribution cabinet specific flexible wire), also known as secondary wire, is a copper core polyvinyl chloride insulated flexible wire, mainly used for power devices and fixed wiring of instruments and meters with AC rated voltage of 450/750V and below that require flexible laying. It is commonly used in distribution cabinets, building decoration, mechanical equipment and other fields, and is also suitable for frequent adjustment of socket circuits, lamp wiring and other occasions in home decoration .
