Product Overview
LXS Aluminium Overhead Aerial Bundle Cable is a 0.6/1kV bare twisted overhead cable with aluminium conductors and XLPE insulation, manufactured to Portuguese standard NP 3528, harmonised European standard HD 626 DMA C33-209, and IEC 60754-1 / EN 60754-1 for halogen-free performance. LXS is the aluminium-conductor counterpart of the copper XS — sharing the same left-hand (S) conductor stranding, right-hand (Z) helical core assembly, and bare (no outer jacket) construction. XLPE insulation serves as both dielectric and weather barrier, enabling outdoor overhead installation on poles and building façades without additional sheathing. LXS is designed for 25-year service life in extreme climates (-60°C to +50°C ambient), with the aluminium conductor offering ~50% weight reduction versus the copper XS for budget-sensitive public distribution networks.
Aluminium Conductor
Class 2 stranded aluminium, left-hand (S) outer layer lay. ~50% lighter than copper XS at the same configuration. Cost-effective for long spans.
XLPE Insulation
Cross-linked polyethylene. 90°C continuous, 130°C overload (8h/day), 250°C short-circuit. No separate outer jacket — insulation is the weather barrier.
Right-Hand (Z) Helical Lay
Cores laid-up helically in right-hand direction. Self-cleaning bundle — ice, snow, and water drain naturally from twisted geometry.
No Outer Sheath
Open bundle design — XLPE insulation directly exposed to weather. Lighter and simpler to install than sheathed ABC. Halogen-free per IEC 60754-1.
Extreme Climate Rated
-60°C to +50°C operating. -20°C min laying. 25-year design service life. Bending radius 10×D. Excellent resistance to external agents.
Aluminium ABC Economics
LXS = aluminium. Copper equivalent is XS. LXS offers lower cost for long-distance public distribution where aluminium's lighter weight reduces pole loading.

Typical Applications
LXS cables are designed for overhead public distribution networks in outdoor environments. The aluminium conductor combined with bare XLPE insulation provides a lightweight, halogen-free solution for pole-to-pole distribution and building façade attachment:
Public Distribution
Overhead distribution for residential and commercial subscribers. Lightweight aluminium reduces pole loading for cost-effective network deployment.
Extreme Climates
-60°C to +50°C operating range. Arctic to desert — wider temperature envelope than sheathed ABC or armoured cables.
Street Lighting
Combined phase + lighting cores in a single twisted bundle. 16mm² auxiliary conductors dedicated to public lighting circuits.
Building Façade Mounting
Suitable for lines attached directly to building façades. Bare XLPE insulation rated for outdoor exposure without degradation.
Portuguese / EU Markets
NP 3528 certified. HD 626 DMA C33-209 ensures acceptance across CENELEC member countries.
Halogen-Free Safety
IEC 60754-1 verified zero halogen acid gas emission. Safe for lines routed through populated areas — no toxic fumes in fire events.
