Product Overview
RVFAV-K Cable is a 0.6/1kV single-core flexible power cable with XLPE insulation and aluminium tape armor. The name follows the Spanish/French designation system: R = flexible Class 5 conductor, V = XLPE insulation, FAV = aluminium tape armor (Facing Aluminum, V = PVC bedding), K = flexible for fixed installation. Unlike all previously described armored cables, RVFAV-K uses aluminium tape rather than steel — this is essential for single-core applications because a ferromagnetic steel armor would generate inductive eddy currents that cause dangerous overheating. The aluminium tape provides equivalent mechanical protection without the magnetic penalty. Additionally, the Class 5 finely stranded conductor gives RVFAV-K a minimum bending radius of only 5 × cable diameter, making it the most flexible armored cable in this product range.
Steel vs Aluminium Armour in Single-Core Cables
| Property | Steel Tape Armour (N2XBY, NYBY...) | Aluminium Tape Armour (RVFAV-K) |
|---|---|---|
| Magnetic Properties | Ferromagnetic — induces eddy currents in single-core | Non-magnetic — safe for single-core AC circuits |
| Conductor Temperature Rise from Armour | Significant in single-core applications | Minimal — no magnetic losses |
| Weight | Heavier | ~30% lighter |
| Mechanical Protection | Excellent — steel is harder | Good — adequate for underground and conduit protection |
| Corrosion Resistance | Requires galvanization | Inherently corrosion-resistant (aluminum oxide passivation) |
| Conductor Flexibility | Class 1 or 2 (solid/stranded) | Class 5 (finely stranded, R ≤5×D bend) |

Voltage Drop Characteristics
For the first time in this product series, voltage drop data (V/A·km) is provided directly in the specification table. Use this to calculate maximum circuit lengths: Max Length = (Permissible Voltage Drop × 1000) / (Vdrop × Current × cos φ). For precise project calculations, contact our engineering team.

Typical Applications
RVFAV-K is specified for single-core flexible installations where ease of installation, tight bend radii, and non-magnetic armor are critical:
Single-Core Power Distribution
Individual phase conductors in 3-phase systems. Aluminium armor eliminates eddy current heating that steel-armored single-core cables suffer from.
Industrial Connections
Flexible connections to motors, generators, and transformers. Class 5 stranding permits easy routing in tight equipment spaces.
Underground Networks
Direct burial in LV distribution networks. Aluminium tape protects against soil pressure and rodent damage.
Outdoor Lighting
Underground feeders for street lighting, parking lot lighting, and outdoor area illumination. UV-stabilized sheath.
Cable Ducts & Conduits
Tight conduit pulls where 5×D bend radius allows installation in confined underground duct networks.
Cold Climate Installations
Rated to -40°C for fixed installations. Flexible PVC sheath remains pliable at sub-zero temperatures.
