25mm² 2 Core PVC SWA XLPE Steel Wire Armoured Cable

Heavy-Duty Armoured Cable Built for Demanding Power Applications

This 25mm² 2-core PVC SWA XLPE cable represents the gold standard for power distribution in challenging environments where durability and safety cannot be compromised. Designed with a layer of galvanised steel wires that protect the inner conductors from impact, pressure, and environmental damage, this cable delivers exceptional mechanical protection in demanding installations.

Unmatched Mechanical Protection for High-Stress Environments

The steel wire armour makes SWA cables highly resistant to crushing, impact, and external damage, making them ideal for underground installations and heavy-duty environments. Unlike standard cables, the robust steel armour layer shields your electrical system from the physical stresses encountered in industrial facilities, construction sites, and outdoor installations where excavation damage, machinery impact, and harsh weather pose constant threats.

Superior Thermal Performance and Current Capacity

The XLPE insulation provides a critical advantage over standard PVC alternatives. Steel wire armoured XLPE cable provides excellent thermal performance, supporting heavier loads with less severe derating than PVC-insulated alternatives. This 2 core, 25mm² SWA cable has a current rating of 146 amps, allowing you to handle substantial power demands without the derating penalties that plague lower-grade cables in confined spaces or grouped installations.

Dual-Function Armour for Simplified Installation

This armour can also be used as a secondary Earth (CPC), eliminating the need for separate earth conductors in many applications. This dual functionality reduces installation complexity and material costs while maintaining full electrical safety compliance.

Direct Burial and Outdoor Installation Without Additional Conduit

Thanks to its strong steel-wire armour, it can be buried directly in the ground without extra piping for protection. This makes the cable ideal for supplying power to remote buildings, agricultural facilities, solar installations, or any outdoor application where running cables through protective ducting would be impractical. The integrated protection eliminates expensive conduit systems while maintaining full mechanical integrity.

Proven Resistance to Environmental Hazards

Armoured cables excel in their resilience against harsh conditions, with the protective armour shielding them from moisture, dust, dirt, and extreme temperatures, ensuring reliable performance even in the most challenging environments. The cable withstands temperature extremes, chemical exposure, and moisture-prone conditions that degrade standard cables.

Enhanced Safety Against Electrical Faults

The armoured layer significantly lowers the risk of electrical faults or fire hazards, and combined with proper earthing, SWA cable provides a safer and more reliable power system. The steel armour also acts as a mechanical safeguard—if the outer sheath is breached during installation or operation, the inner insulation remains protected.

Standards Compliance and Long Service Life

Armoured XLPE SWA mains cables are manufactured to British Standard BS5467 and are suitable for power networks. SWA cables are built for long-term use, even in harsh environments such as moisture, corrosion, and high mechanical stress, reducing maintenance costs and ensuring stable operation. This investment in a properly specified cable pays dividends through reduced downtime and lower lifetime ownership costs.

Versatile for Multiple Installation Methods

Whether you're running power to agricultural sites, renewable energy installations, industrial operations, or residential outbuildings, this cable adapts to your requirements. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting, it delivers reliable performance in both hidden and exposed installations. The 25mm² cross-section provides the capacity needed for substantial power demands without requiring multiple cable runs.

Professional Installation Considerations

Proper termination is essential—use compatible brass or metal cable glands that grip the armour properly and always earth the steel wire layer for safety compliance. The cable's weight and rigidity, while enhancing durability, require appropriate handling equipment and installation planning. Consulting with a qualified electrician ensures compliance with local electrical codes and optimal system performance.
