1.5mm 3 Core SWA Steel Wire Armoured Cable 25m Reel

Premium Single-Phase Power Cable for Outdoor, Underground & Harsh Environments

This 1.5mm 3 Core SWA armoured cable delivers the mechanical protection you need for challenging installations where standard cables fail. Featuring a PVC outer sheath and steel wire armour below, this construction protects the cores inside the cable which makes it suitable for direct burial into the ground. The compact 1.5mm diameter makes routing around obstacles and through tight spaces straightforward—critical for outbuildings, sheds, and properties where space is limited.

What This Cable Is Built For

This cable is primarily made for carrying mains power to low power lighting circuits whilst also being perfect for 13A switches and sockets. Domestically, this type of electrical cable is ideal for outdoor installations, with examples including installing water features in gardens, powering outdoor sheds and ideal for powering hot tubs. It's equally at home running outdoor garden lighting, supplying power to detached garages, or feeding temporary construction site installations.

Superior Mechanical Protection You Can Rely On

Thanks to the steel wire armouring, SWA cables are far more durable than standard electrical cables. They can withstand harsh environmental conditions, mechanical stress, and even potential impacts. Their ability to withstand impact, crushing, rodents and environmental hazards makes them the preferred choice for safeguarding electrical systems in demanding environments. Unlike standard unarmoured cables that require expensive conduit protection, this SWA cable can be buried directly in the soil, exposed to weather, moisture, or chemicals, and handle high-traffic areas where cables could be crushed or impacted.

Three-Core Design Built for Single-Phase Circuits

The 3-core SWA cable is predominantly used for single-phase wiring to provide a single live wire, neutral wire, and earth conductor. This makes the 1.5mm size ideal for lower-demand single-phase applications. The cable features plain annealed stranded copper for the cores, insulated with a cross-linked polyethylene coating with bedding and sheathing made from PVC.

Standards & Safety Compliance

Manufactured to BS5467 Electric cables standard, this thermosetting-insulated, armoured cable carries a 600/1000V voltage rating. The XLPE/PVC construction provides both high temperature resistance and excellent environmental protection.

25-Meter Reel Ready to Install

This convenient 25m reel eliminates the need to order by the metre for most single-site installations. While SWA cables may seem like a more expensive option compared to standard cables, their long-term durability and reduced maintenance needs make them a cost-effective choice. The initial investment often leads to fewer repairs and replacements. Pair with appropriate glands (CW20S for outdoor terminations) and cable cleats (CC5) for a complete installation.

When Standard Cable Just Won't Do

Choose this armoured cable when your installation faces moisture, mechanical damage risk, underground or direct burial conditions, or harsh outdoor environments. Long-term durability and reduced maintenance needs make them a cost-effective choice. The steel wire armour provides protection that standard cables cannot match without expensive external conduit systems.
