1.5mm² 27 Core SWA XLPE Armoured Cable Cut To Length

Multi-Core SWA Armoured Cable Built for Harsh Environments

The 1.5mm² 27 Core SWA XLPE cable is engineered for electrical installations where mechanical protection and durability are non-negotiable. Designed with a layer of galvanised steel wires that protect the inner conductors from impact, pressure, and environmental damage, this cable delivers robust performance across industrial, outdoor, and underground applications where standard unarmoured cables would fail.

Superior Protection Without Compromise

SWA cables deliver outstanding mechanical protection, dual-function armour as CPC, high current-carrying capacity in power cables, and steel wire armoured XLPE cable provides excellent thermal performance, supporting heavier loads with less severe derating than PVC-insulated alternatives. The 27-core configuration visible in the cable's cross-section provides optimized current distribution for demanding multi-circuit applications.

The steel wire armour layer serves a triple function: mechanical shield against crushing and impact, protective conductor for fault currents, and structural support during installation. The galvanized steel layer provides a robust shield against accidental shovel strikes during excavation, rock pressure in deep trenches, and heavy vehicle traffic on construction sites.

Ideal for Direct Burial and Outdoor Installations

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. They are suitable for direct burial into free draining soil or can be clipped directly onto a surface, on a tray, in a basket or in free air. Unlike unarmoured alternatives, this cable eliminates the need for expensive conduit protection in buried installations.

XLPE Insulation for Enhanced Performance

Most SWA cables are thermosetting insulated. Thermosetting cables are capable of operating at conductor operating temperatures of 90 °C, providing superior thermal stability and longer service life compared to PVC-insulated cables. XLPE cable is highly thermally resistant. The type of cable has a higher current carrying capacity and operating temperature, therefore it has a longer lifespan in underground installations.

Real-World Application Reliability

Smaller sizes, such as 1.5mm to 4mm, are typically used for lighting and low-demand circuits, making the 1.5mm² cross-section suitable for a range of lighting systems, garden installations, and auxiliary power distribution. 1.5mm armoured cable is perfect for small, low power outdoor lighting circuits and to connect to small generators.

Built to British Standards

SWA Cable primarily complies with BS 5467 (UK) for XLPE-insulated, PVC-bedded and sheathed armoured cables, and IEC 60502-1 for extruded solid dielectric cables rated up to 1 kV. These standards define construction details, voltage testing, insulation properties, armour conductivity, and mechanical performance. Compliance ensures the cable meets UK electrical safety regulations and performs reliably in fixed installations.
