H07V-U, H07V-R and H07V-K are PVC-insulated harmonised cables with a 450/750 V rated voltage. The principal decision point among these three products is the copper conductor construction: H07V-U has a solid conductor, H07V-R has a stranded conductor, and H07V-K has a fine-stranded conductor. This difference is relevant when assessing cable routing, panel installation approach and the documented usage information.
This comparison applies only to the H07V-U, H07V-R and H07V-K product family. The products should not be considered direct substitutes; cross-section, installation conditions, terminal type, circuit length, voltage drop and applicable standards should be evaluated together on a project-specific basis.
Key differences by conductor construction
H07V-U: solid copper conductor
H07V-U has a solid copper conductor and PVC insulation. According to its documented usage information, it may be used in panels, protected building installations, main distribution boards, switching and control equipment, installations in conduit, and fixed lighting circuits. It is specified for fixed and protected installations rather than connections subject to continuous movement or frequent bending.
H07V-R: stranded copper conductor
H07V-R has a stranded copper conductor. Its documented applications include main distribution boards, switchgear systems, control panels and protected fixed circuits inside buildings. It is described as providing routing convenience at larger cross-sections and is specified for installations that remain fixed after installation. It is not as flexible as H07V-K and is not specified for systems involving continuous movement or repeated bending.
H07V-K: fine-stranded copper conductor
With its fine-stranded copper conductor, H07V-K has documented usage information for connections requiring installation flexibility within these three products. It may be used in distribution and control panels, switching equipment, protected connections inside machinery, and fixed systems where flexibility is required during installation. The fine strands are stated to require termination with suitable connection accessories. The cable should be protected from outdoor applications exposed to continuous mechanical stress.
Selection approach for the 450/750 V product family
Common documented characteristics
All three cables are PVC-insulated and have a 450/750 V rated voltage. The test voltage is documented as 2-2.5 kV for all three products, while the operating temperature is 70 °C and the insulation material is documented as PVC(TI1). The insulation colour standard is stated as TS 9758, the conductor resistance standard as TS EN 60228, and the flame test standard as TS EN 60332-1-2.
The construction standard records list “TSE EN 50525-2-31; TSE IEC 60227; VDE 0281” for H07V-U and H07V-K, and “TS EN 50525-2-31; TSE IEC 60227; VDE 0281” for H07V-R. The minimum bending diameter is documented as 6xD, 12xD for H07V-U and H07V-R, and as 6xD for H07V-K.
Documented cross-sectional range
The source technical rows list cross-sections of 1.50–16 mm² for H07V-U, 1.50–240 mm² for H07V-K and 1.5–500 mm² for H07V-R. The documented cross-sectional range alone does not determine suitability for a specific application or constitute a selection outcome; it should be assessed together with project conditions.
