Product Overview
LXRV Cable is a 0.6/1kV XLPE-insulated steel wire armoured PVC-sheathed power cable with aluminium conductor, manufactured to the Spanish national standard UNE 21123-2 and international standard IEC 60502-1. Naming follows Spanish UNE convention: L = aluminium conductor (aluminio), X = XLPE insulation (polietileno reticulado), R = round steel wire armour (armadura de alambres de acero), V = PVC outer sheath. For single-core AC circuits, steel armour wires are substituted by aluminium wires (designated IR) to prevent eddy current heating. LXRV is the standard Spanish SWA cable for outdoor fixed installations requiring mechanical protection against aggression, rodents, and direct burial. Available with both circular stranded and sector-shaped conductors, the latter offering a more compact cable diameter for the same cross-section.
PVC Jacket — Black PVC type ST 2, UV resistant
Steel Wire Armour — Galvanized wires, helical applied
PVC Bedding — Extruded separation sheath
XLPE Insulation — 90°C, HD 308 S2 colour coded
Aluminium Conductor — Class 2, circular or sector shaped
Aluminium Conductor
Class 2 stranded per IEC 60228. Available in circular (standard) and sector-shaped (compact) configurations. Sector-shaped reduces overall cable diameter.
XLPE Insulation
90°C continuous, 250°C short-circuit (max 5s). Test voltage 3.5kV AC (5 minutes). Insulation resistance ≥20 MΩ×km.
PVC Bedding
Extruded PVC separation sheath. Protects XLPE insulation from steel wire abrasion during bending and thermal cycling.
Steel Wire Armour
Galvanized steel wires, helical applied. Substituted by aluminium wires (IR) for single-core AC circuits to prevent eddy current losses.
PVC Jacket (ST 2)
Black PVC type ST 2 per UNE 21123-2. Flame retardant (IEC 60332-1). High resistance to UV, moisture, and mechanical abrasion.
Circular vs Sector
Left: standard stranded circular. Right: sector-shaped — compact diameter, less bedding material, lighter weight per ampacity. Both available across the range.

Typical Applications
Outdoor Fixed Installation
Designed for outdoor environments where mechanical aggression or rodent threat requires armoured protection. Direct burial, ducts, or free air.
Underground Distribution
Direct burial in soil for LV power distribution. SWA provides superior mechanical protection during laying, installation, and service life.
Industrial Networks
Power supply to factories and production facilities. 10×D bending radius allows routing through conduits and tight spaces.
Spanish & LATAM Markets
UNE 21123-2 certified for Spain and Latin American countries where UNE standards are adopted or referenced in local regulations.
Renewable Energy
LV collection in solar farms where aluminium conductor economics and SWA mechanical protection are required for field installation.
Infrastructure
Water treatment plants, pumping stations, and transport infrastructure requiring UNE-certified armoured power cable.
