Product Overview
Zhenglan Cable Technology Co., Ltd. manufactures H07V-U harmonized building wire — a 450/750 V single-core, PVC-insulated, non-sheathed copper cable for fixed installation in buildings. H07V-U uses a solid (Class 1) plain copper conductor with a single PVC insulation layer, intended for wiring inside conduits, switchboards and fixed protected routes in European and export markets.
The 1×2.5 mm² size is the most common final-circuit conductor for sockets and lighting in residential and commercial buildings.
