Each core combines 25 strands of copper wire and 20 strands of copper-clad aluminium (CCA) in a hybrid construction that balances conductivity and cost. The black PVC outer sheath measures 7.8mm in diameter and provides mechanical protection for indoor runs through ceilings, walls and conduit.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial PA installations in retail spaces, offices, schools and hospitality venues, the 1.15mm² cross-sectional area handles loads up to 15A maximum current. This makes it suitable for multi-speaker distributed systems where individual speaker runs draw modest current but total system draw can reach higher levels. The 100m reel length supports typical single-zone installations without requiring mid-run joints, reducing points of potential failure.\u003c\/p\u003e\n\u003cp\u003eThe hybrid copper\/CCA conductor construction provides DC resistance lower than pure CCA cable while remaining lighter and more cost-effective than pure copper for budget-conscious installations. The 7.8mm outer diameter keeps the cable profile compact enough for discreet installation behind skirting, within cavity walls or bundled in ceiling voids alongside mains and data cabling. The black sheath blends into commercial environments where exposed cable runs are unavoidable.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eConductor\u003c\/td\u003e\n\u003ctd\u003eCopper\/Copper Clad Aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e1.15mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (25 x 0.18mmØCu + 20 x 0.18mmØCCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e7.8mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e1 reel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e15A max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between this and pure copper speaker cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis cable uses a hybrid conductor combining copper and copper-clad aluminium (CCA). Pure copper offers lower DC resistance and better long-term reliability, while the hybrid construction reduces cost and weight. For typical 100V line runs under 50m the performance difference is negligible in practice.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this suitable for outdoor use?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The black PVC sheath is rated for indoor installation only. For outdoor 100V line runs between buildings or in weather-exposed positions, use a cable with UV-resistant or armoured sheathing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat current does the 1.15mm² CSA support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe cable is rated for a maximum continuous current of 15A. In practice, 100V line systems distribute power across multiple speaker drops, so individual runs typically draw far less than the maximum rating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this for low-impedance speaker connections?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided the run is short. The 1.15mm² cross-section is adequate for low-impedance (4-8 ohm) speaker connections up to approximately 5-10m, but for longer runs or higher-power applications a larger CSA cable is recommended to minimise resistance losses.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313496187147,"sku":"801.818UK","price":76.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/801818UK_LD1_72d1f1ca-739b-4bf0-a015-86ada96ae5e9.jpg?v=1715194589","url":"https:\/\/niori.co.uk\/products\/mercury-100v-line-speaker-cable-1-15mm-black-100m-reel","provider":"Niori","version":"1.0","type":"link"}
