Product Overview
BS6004-compliant H07V-U, H07V-R, and H07V-K cables are single-core, PVC-insulated copper conductors rated at 450/750V. Designed for internal wiring and fixed installations, these non-sheathed cables offer reliable electrical performance in enclosures, conduits, and protected environments. They feature solid (Class 1), stranded (Class 2), or flexible (Class 5) conductors to suit diverse installation requirements.

-
Flexibility Options: Class 5 (H07V-K) for tight bends; Class 1/2 (H07V-U/R) for static routes.
-
Chemical Resistance: PVC resists oils, moisture, and abrasion in controlled environments.
Application Scenarios
-
Electrical Enclosures: Switchboards, distribution panels, control cabinets.
-
Internal Wiring: Lighting circuits, industrial machinery, transformers.

-
Ideal For:
-
H07V-U/R: Rigid installations with infrequent maintenance.
-
H07V-K: Dynamic applications requiring frequent flexing.
