H07

H07 is a designation used primarily within European electrical cabling systems to classify a family of low-voltage power cables and cords. It appears as part of a broader naming convention for flexible and fixed-installation cables, where the H07 prefix designates a category within the IEC/EN standards. The designation is used in several variants that specify insulation and sheath materials, temperature ratings, and intended use, for example H07RN-F, H07V-U, and H07V-K.

H07RN-F denotes a rubber-insulated, flexible power cable with an outer sheath, typically rated for 450/750 V and used for portable equipment and temporary installations. H07V-K and H07V-U designate PVC-insulated and sheathed cables for fixed installations, with similar voltage ratings and temperature classes. The exact properties vary by variant and standard, but all H07 cables are designed for low-voltage power transmission and domestic or industrial applications.

In standards, H07 cables are governed by European and international specifications such as EN 50525 and related IEC harmonization, which address conductor material, insulation, sheath, temperature performance, fire behavior, and mechanical durability. The precise requirements depend on the variant (rigid vs flexible, rubber vs PVC insulation, and outdoor or indoor use).
