Whether you're running power to outdoor structures, burying cable underground, or working in high-risk environments, this cable's multi-layered construction shields your electrical system from the physical stresses that would quickly compromise unarmoured alternatives.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eEngineered Construction That Lasts Decades\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eBuilt with stranded copper conductors, XLPE insulation rated to 90°C, PVC bedding, and galvanised steel wire armour, every component serves a specific protective function. The XLPE insulation handles higher operating temperatures than standard PVC, allowing the 4mm² conductors to carry their 42-amp current rating reliably even under demanding conditions. The steel wire armour wraps around the insulation—not exposed directly—so it's defended by an outer PVC sheath that resists moisture, UV exposure, and chemical hazards.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eDirect Burial Capability Without Additional Conduit\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe steel wire armour eliminates the need for expensive protective ducts when burying cable underground. You can install this cable directly into free-draining soil at depth, and the galvanised steel provides continuous mechanical protection against crushing, rodent damage, and impact from digging or ground movement. This reduces both material costs and installation complexity compared to running unarmoured cable through separate conduit.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eReal-World Applications That Depend on Durability\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe 3-core configuration (live, neutral, and earth) makes this cable ideal for single-phase power distribution in single-phase circuits with grounding. Common installations include outdoor garden lighting systems, sheds and outhouses, external pond pumps and switching circuits, security lighting, electric gates, detached workshop power supplies, and temporary construction site feeds. You can also use it to connect renewable energy systems—including solar arrays—to grid infrastructure or property wiring.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eSuperior Performance in Harsh Environments\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eWhere temperature extremes, moisture saturation, chemical exposure, or mechanical stress would degrade unarmoured cables, XLPE insulation maintains electrical integrity. The cross-linked polyethylene structure provides higher insulation resistance and better resistance to water ingress than thermoplastic alternatives, extending service life across industrial sites, manufacturing facilities, construction areas, coastal installations, and situations where cables face twisting, crushing, or impact.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eStandards Compliance and Long Service Life\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eManufactured to BS 5467 specifications for low-voltage armoured cables rated 600\/1000V, this cable meets stringent safety and performance requirements across the UK and EU. The robust construction typically delivers 20–30+ years of reliable service under normal conditions, reducing replacement frequency and long-term maintenance costs. The 25-metre reel provides a practical pre-cut length for smaller projects without excessive surplus.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eProper Termination and Support\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eWhen terminating this cable, use CW20 outdoor cable glands for external connections or BW20 indoor glands for internal terminations. Secure the cable with CC6 cable cleats to prevent stress on termination points. The armour must be properly bonded to earth at both ends to ensure safe fault current paths and prevent electrical shock risk—this is essential regardless of installation environment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"swa cable","offers":[{"title":"Default Title","offer_id":54292774715719,"sku":"H6943XL4.0025","price":101.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/1156\/5895\/files\/cable_h6943x_2753701b-0357-4dcd-ad71-387eec5b36d8.jpg?v=1783243435","url":"https:\/\/electricallighting.co.uk\/products\/4mm-3-core-pvc-swa-xlpe-armoured-cable-25m-reel","provider":"Electrical Lighting ","version":"1.0","type":"link"}
