4mm 7 Core SWA XLPE Armoured Cable For Power Distribution

Heavy-Duty Power Distribution Cable Built for the Harshest Environments

The 4mm 7-core SWA XLPE armoured cable is engineered for applications where durability and mechanical protection are non-negotiable. Designed for low-voltage connections with a maximum rating of 50Vdc, this multicore cable delivers reliable power transmission across demanding installations from industrial facilities to renewable energy systems.

Superior Construction for Maximum Protection

The XLPE insulation delivers higher insulation resistance values, increased mechanical protection and resistance to chemical corrosion and water, while galvanised steel wires are applied helically to ensure near-100% coverage and high impact resistance. The black PVC outer sheath provides UV resistance and weatherproofing, making this cable suitable for extended outdoor exposure without degradation.

What sets this cable apart is its ability to handle both mechanical and environmental stress simultaneously. SWA cables reduce fault risks in underground or exposed runs, support high-load circuits, and integrate effectively with circuit breakers and protective devices. The 7-core configuration provides flexible current-carrying options for three-phase power systems with neutral and earth conductors, or parallel neutral arrangements where increased capacity is needed.

Proven Performance in Real-World Applications

The cable is best equipped to be installed straight underground with no extra conduit or trunking, with steel armour wire providing protection against undesired impression while excavating and also pressure and soil displacement. This makes direct burial installation straightforward and cost-effective.

Factories, warehouses, and building sites use SWA cables to energize heavy-duty machinery, conveyor belts, and lighting, while SWA cables are mostly used in solar and wind energy systems for power transmission from the place of generation to the main distribution board. The cable's temperature rating of 90°C allows sustained operation in warm climates and equipment-dense facilities without derating.

Standards Compliance & Long Service Life

Compliance with rigorous standards such as BS 5467 and IEC 60502, and proven performance in demanding conditions make it the preferred choice for electrical contractors facing mechanical and environmental challenges. Armoured cables are typically designed to last more than 30 years, with XLPE SWA cables resistant to water ingress, chemicals, and temperature fluctuations (-20°C to 90°C).

Installation Flexibility Across Multiple Environments

These cables are used for power networks, direct burial, outdoors, indoors and in cable ducts for electricity supply in low voltage installation system. Whether you're connecting outbuildings, powering industrial equipment, or laying cables for renewable energy projects, the 4mm core size offers the right balance of current capacity and flexibility for mainstream applications.

The armour provides superior tensile strength, allowing the cable to endure pulling forces during installation and minor ground movement post-burial, reducing the risk of installation damage and future failures from ground settlement or movement.

Safety & Regulatory Confidence

In the majority of applications, the armour itself can double as an earth conductor, simplifying grounding arrangements and reducing installation complexity. Due to their durability, armoured power cables are ideal for use in harsh and potentially hazardous environments and are designed to supply an uninterrupted electrical connection, offering increased protection, and therefore decreasing the risk of power loss.

Choose this cable when reliability matters—where cable damage could disrupt operations, compromise safety, or require expensive repairs. The upfront investment in armoured construction pays dividends through decades of trouble-free service in challenging applications.
