6mm² 3 Core PVC SWA XLPE Armoured Cable Length Metre

Professional-Grade Armoured Power Cable for Demanding Installations

The 6mm² 3 Core PVC SWA XLPE Armoured Cable is engineered for power distribution and transmission in applications where mechanical protection isn't optional—it's essential. With 6mm² copper conductors, rigid XLPE insulation colour-coded brown, black and grey, rated 600/1000V for distribution circuits and high-current installations, steel wire armour safeguards against impact and abrasion, whilst the compact 15.6mm profile, PVC sheath and -15 to 90°C operating range provide dependable performance in challenging locations.

Why Armoured Cable Matters

The main difference between armoured and unarmoured cable is the presence of a protective metallic layer designed to improve resistance against mechanical impact, crushing, abrasion, or other external stress during and after installation. Steel wire armour provides mechanical protection, which means the cable can withstand higher stresses, be buried directly and used in external or underground projects. This is why SWA cable is the industry standard for underground installations and outdoor power networks.

Perfect for Real-World Applications

Common applications for LV armoured cables include the supply of mains electricity and for auxiliary control cables in diverse environments including aerial power networks, outdoors, indoors, underground systems and in cable ducting. 6mm x 3 Core SWA cable is generally used for garden lighting, street lighting, industrial ring mains, power radial circuits as well as a whole host of other uses.

The 3-core configuration makes this cable particularly versatile—three core SWA cables are live, neutral and earth, for Class I or Single Insulated which must have earth connections. Whether you're connecting solar installations, powering outbuildings, or running circuits across construction sites, this cable handles the load without compromise.

Superior Performance in Harsh Conditions

Modern steel wire armoured XLPE cable employs cross-linked polyethene (XLPE), offering superior short-circuit withstand, lower dielectric losses, and higher temperature tolerance compared with traditional PVC. XLPE insulation acts as a waterproof barrier around each conductor, preventing internal moisture absorption, steel wire armour provides structural support and acts as a physical barrier against punctures, and the durable PVC outer sheath forms a continuous, impermeable layer that resists water penetration, UV degradation, and chemical exposure.

The protective armour effectively deters rodents and other pests, which can wreak havoc on unarmoured cables and cause costly disruptions. This makes it ideal for direct burial applications where underground pests pose a real threat to unprotected cables.

Proper Installation and Capacity

A 6mm² copper SWA cable can safely carry between 34A and 47A for single-phase circuits, or higher for three-phase installations. For accurate sizing, the ampacity depends on several factors, including the installation method, temperature, and type of load. Always consult local electrical standards and a qualified electrician to confirm the correct cable size for your specific application.

For 6mm SWA armoured cable, the typical gland size is 20mm (known as BW20 or CW20 depending on the type)—BW glands for indoor installations where the cable isn't exposed to moisture and CW glands for outdoor use, offering weatherproof sealing.

Built to Last

With proper installation, these cables can last 25+ years in stable environments. SWA Cable primarily complies with BS 5467 (UK) for XLPE-insulated, PVC-bedded and sheathed armoured cables. This certification means you're getting a cable that meets rigorous British Standards and is trusted across industrial, commercial, and residential installations.

Available in single-metre lengths or custom cut to your exact requirements, this SWA armoured cable delivers the reliability and durability that demanding projects demand.
