What is Sheathed Wire?
Sheathed wire refers to single-core or multi-core wires with an outer protective sheath, offering enhanced safety. Simply put, the most commonly used "sheathed wire" consists of a white PVC jacket enclosing several BV wires inside. This type of wire generally uses copper conductors, with an insulation layer around the conductor plus an additional outer protective layer. Common sheathed wire types include RVV, BVV, RVVB, and BVVB. Sheathed wires can be divided into hard sheathed wire and soft sheathed wire. Based on application environment and shape, they are classified into round sheathed wire (typically multi-core) and flat sheathed wire (typically single-core).
