Product Overview
RVFV-K Cable is a 0.6/1kV flexible armored power cable available in single-core through 61-core configurations. Naming: R = flexible Class 5 conductor, V = XLPE insulation, FV = tape armor (steel or aluminium), K = flexible for fixed installation. It is the general-purpose flexible armored cable — single-core versions use non-magnetic aluminium tape to prevent eddy current heating, while multi-core versions (both steel and aluminium tape are acceptable) since opposing magnetic fields from balanced phases cancel out. The Class 5 finely stranded conductor gives a bend radius of only 5 × D for single-core and 6-8 × D for multi-core — the most flexible armored cable family available in the 0.6/1kV range.

Cable Construction

1. Conductor — Class 5 flexible copper, EN 60228
2. XLPE Insulation — 90°C rated
3. PVC Bedding — Separation sheath
4. Tape Armour — Steel or aluminium, double layer
5. PVC Outer Sheath — Flexible PVC, black
Flexible Copper Conductor
Class 5 finely stranded per EN 60228. Allows tight bend radii (5-8×D) impossible with Class 2 stranded cables.
XLPE Insulation (V)
Cross-linked polyethylene, 90°C continuous. XLPE chosen over PVC for higher current capacity in flexible armored cables.
PVC Bedding
Extruded PVC separation sheath between laid-up cores and armor. Provides smooth bedding surface and protects insulation.
Tape Armour (FV)
Double steel or aluminium tape, helically applied. Steel for multi-core (cost-effective, field-cancelling). Aluminium for single-core (non-magnetic).
Flexible PVC Sheath
Black flexible PVC. Maintains pliability at sub-zero temperatures while providing mechanical and chemical protection.
Installation Versatility
Open air, buried, in conduit. -5°C min installation, -40°C service. Meter-by-meter marking.
