Commonly used for mains electrical supply, this cable combines three critical layers of engineering to handle the toughest installation environments where non-armoured cables simply won't survive.\u003c\/p\u003e \u003ch3\u003eThree-Layer Protection You Can Trust\u003c\/h3\u003e \u003cp\u003eThe engineering behind this cable sets it apart from basic power cables. The 3 copper conductors deliver a current rating of 42 amps, making it suitable for mid-range power distribution in residential and commercial applications. The 4mm² cable features XLPE insulation with galvanised round steel wire armour—creating a protective buffer that extends the cable's lifespan and reliability.\u003c\/p\u003e \u003cp\u003eWhat makes armoured cable essential? Steel wire armour shields the cable from impact, moisture, and mechanical stress, while armour protects cables from damage by animals or shovels in direct burial applications. This is critical for outdoor and underground installations where accidental damage is a genuine risk.\u003c\/p\u003e \u003ch3\u003eXLPE Insulation: Superior to Standard PVC\u003c\/h3\u003e \u003cp\u003eXLPE cable is highly resistant to heat, moisture, and chemicals, making it ideal for applications exposed to harsh environmental conditions, such as underground or underwater installations. The technical advantage is measurable: XLPE can maintain excellent strength and toughness under mechanical stresses such as tension, bending and impact, particularly for underground cables. The cross-linked structure enables XLPE to maintain stable performance in long-term outdoor exposure environments—a concern when dealing with UV radiation and oxidation that degrades lesser cables.\u003c\/p\u003e \u003ch3\u003eReal-World Applications\u003c\/h3\u003e \u003cp\u003eThe 3 core 4mm cable can be used in supplying power to outbuildings, garden lighting or security systems. Beyond residential use, armoured cables are used for industrial and commercial machinery, making them versatile across multiple sectors. The cable is suitable for outdoor installations in damp conditions where mechanical damage is likely, can be installed in duct or clipped directly to surfaces, and may be laid direct in ground or embedded in concrete.\u003c\/p\u003e \u003ch3\u003eKey Technical Specifications\u003c\/h3\u003e \u003cp\u003eThis cable meets BS 5467—widely used in the UK as well as international projects adhering to British standards. The cable features Class 2 stranded copper conductors with a voltage rating of 0.6\/1 kV. The cable is designed for mains supply electricity, both externally and buried underground, with the cable size referring to the cross-sectional area of conductors, while the overall cable diameter including insulation and sheath will be larger than the stated conductor size.\u003c\/p\u003e \u003ch3\u003eWhy Armoured Over Non-Armoured?\u003c\/h3\u003e \u003cp\u003eIn underground applications, armoured cables with XLPE insulation provide reliable and secure power transmission, safeguarding electrical infrastructure from potential damage due to soil pressure, excavation activities, or accidental impacts. While non-armoured cables cost less, they lack the mechanical resilience required in exposed, outdoor, or buried installations. Armoring provides crucial mechanical strength, allowing the cable to resist external forces such as mechanical stress and impacts, making products well-suited for installation in challenging environments including underground, outdoor, and industrial settings where risk of physical damage is higher.\u003c\/p\u003e \u003ch3\u003eIdeal for Demanding Projects\u003c\/h3\u003e \u003cp\u003eWhether you're running power to a remote outbuilding, connecting garden lighting, establishing an emergency power supply, or handling industrial distribution, this cable handles temperature extremes from -15°C to +90°C. The combination of XLPE insulation's thermal stability with steel wire armour protection means fewer failures, fewer costly replacements, and greater safety in installations where cable damage could cause downtime or hazards. For projects where durability, code compliance, and reliable power delivery are non-negotiable, this is the cable that delivers.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"swa cable","offers":[{"title":"Default Title","offer_id":54292769898823,"sku":"H6943XL4.0","price":4.48,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0966\/1156\/5895\/files\/cable_h6943x_40655d52-374c-46b4-8bbf-637ebe598cf6.jpg?v=1783243403","url":"https:\/\/electricallighting.co.uk\/products\/4mm-3-core-pvc-swa-xlpe-armoured-cable-cut-length-sold-by-the-metre","provider":"Electrical Lighting ","version":"1.0","type":"link"}
