25mm 4 Core PVC SWA XLPE Armoured Cable Sold Metre

Professional-Grade Protection for Demanding Installations

This 25mm 4 Core SWA XLPE Cable is engineered for applications where standard electrical cables simply won't survive. Built with galvanised steel wire armour, cross-linked polyethylene (XLPE) insulation, and a robust PVC outer sheath, this cable delivers the mechanical protection necessary for underground power distribution, industrial facilities, construction sites, and outdoor infrastructure—including solar panel grid connections.

What Sets This Cable Apart

Superior Temperature Performance
The XLPE insulation allows continuous operation at up to 90°C conductor temperature, compared to standard PVC cables rated at significantly lower temperatures. This thermosetting construction also provides higher insulation resistance values and better resistance to chemical corrosion and moisture, extending service life in challenging environments.

Heavy-Duty Mechanical Protection
The helical steel wire armour layer provides exceptional resistance to crushing, impact, and tensile stress. Whether buried underground, dragged across rough terrain, or installed in high-traffic industrial areas, the 90%+ coverage armour shields the internal conductors from damage that would compromise unarmoured cables. This protective layer also functions as a circuit protective conductor (earth wire), enhancing safety redundancy.

Flexible Installation Options
Unlike single-function cables, this 4-core design accommodates various circuit configurations. The four individually insulated copper conductors (brown, black, grey, blue) provide flexibility for three-phase power, single-phase circuits with neutral and earth, or combinations suitable for control and auxiliary applications.

Direct Burial & Outdoor Capability
The black PVC outer sheath is UV-resistant and moisture-proof, enabling safe direct burial in free-draining soil (typically at 450mm depth) or installation on exterior surfaces without additional conduit protection. The cable withstands soil pressure, moisture infiltration, and temperature fluctuations from -15°C to +90°C.

Compliance & Standards
Manufactured to BS 5467, this cable meets UK electrical installation standards and is suitable for 600/1000V applications. The construction includes Class 2 stranded copper conductors, PVC bedding for internal protection, and galvanised steel armour—all components tested for mechanical strength, electrical continuity, and fire performance (BS EN 60332-1-2 flame retardant).

Common Applications

• Underground mains power supply to industrial units, warehouses, workshops, and outdoor buildings
• Solar farm AC connections between inverters, transformers, and grid interconnection points
• Fixed outdoor installations including street lighting, gate barriers, and remote monitoring systems
• Submain and distribution board connections in harsh or exposed environments
• Power supply for temporary construction installations and site infrastructure
• Agricultural and rural electrification where mechanical resilience is essential

Installation Considerations

Maintain a minimum bending radius of 12–15 times the cable diameter during installation to prevent insulation or armour damage. The cable is heavy, requiring proper support spacing in free-air runs and additional clamps for vertical installations. Use approved BW or CW cable glands for terminations to maintain the integrity of the armoured layer and ensure proper earthing. Secure to surfaces using armoured cable cleats at 450mm intervals for both mechanical and safety compliance.
