APPLICAZIONE
H07V-K Cable is flexible, single-core PVC-insulated hook-up wire designed for protected installations.
Ideal for the internal wiring of switchgear, distributor systems, control cabinets (including those for high and medium-voltage infrastructure), macchinari, and electrical panels. Also suitable for laying in conduits (on or under plaster) and closed installation ducts for domestic and industrial lighting circuits.

FAQs of XWA H07V-K Cable
What does the designation H07V-K stand for?
The H07V-K naming convention follows the European harmonized standards (HAR) for cable identification.
- “H” sta per Approvazione Armonizzata
- “07” denota una tensione nominale di 450/750 V
- “V” indicates the standard PVC (Cloruro di polivinile) isolamento
- “K” signifies a flexible, fine-wire copper conductor (Classe 5) that is intended for fixed installations.
Detailed regulations for this coding can be found in EN 50525-2-31.
What is the main difference between H07V-K, H07V-U, and H07V-R?
While all three are single-core, PVC-insulated cables rated for 450/750V, the difference lies entirely in the flexibility of the copper conductor:
- H07V-K: Features a flexible fine-wire conductor (Classe 5). It is the easiest to bend and route through tight spaces, making it the top choice for complex control panels and switchgear.
- H07V-U: Features a solid, single-wire conductor (Classe 1). It is rigid and typically used for straightforward, permanent installations where bending is minimal.
- H07V-R: Features a stranded conductor (Classe 2), offering a middle ground. It is more flexible than solid wire but less flexible than the “K” variant, often used for heavier power circuits.
Can H07V-K cable be used outdoors or directly buried in the ground?
NO, H07V-K is a single-core insulated wire without a protective outer sheath. It is not UV-resistant, nor is it designed to withstand moisture, mechanical impact, or direct soil contact. If used outdoors or in exposed environments, it must be securely enclosed within protective conduits, cable trunking, or weather-proof electrical panels.
Is H07V-K wire flame retardant?
SÌ, the PVC insulation used in H07V-K cables is self-extinguishing and flame retardant according to standard IEC 60332-1-2. Tuttavia, because it is made of PVC, it will release smoke and halogen gases if exposed to a severe fire. If your project requires installation in public buildings with strict fire safety codes (like hospitals or airports), you should consider our H07Z-K cable, which is the Low Smoke Zero Halogen (LSZH) equivalent.
What are the most commonly used H07V-K specifications and colors?
Because H07V-K is primarily used for panel wiring and circuit identification, it is highly requested in a wide variety of solid and bi-colors (such as Green/Yellow for grounding, Blue for neutral, and Brown/Black/Grey for phases). The most frequently utilized cross-sectional sizes include:
- Light Control & Domestic Circuits: The H07V-K 1×1.5 and H07V-K 1×2.5 are heavily used for standard lighting, relay wiring, and internal cabinet connections.
- Medium Power Distribution: The H07V-K 1×4 and H07V-K 1×6 are standard for feeding sub-circuits and industrial machinery components.
- Main Feeds & Heavy Equipment: For main grounding lines and larger switchboard power feeds, thicker gauges like H07V-K 1×16, H07V-K 1×25, and H07V-K 1×35 are the industry standards.
