Each core carries 24 strands in a 0.75mm² cross-sectional area, split between 12 oxygen-free copper strands and 12 CCA (copper-clad aluminium) strands for a balance of conductivity and flexibility.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and commercial audio installations where cable needs to be routed through tight bends, behind walls or under floors, the Mercury Hi-Flex combines a 7mm outer diameter with double insulation to maintain flexibility without compromising the conductor count. The LSZH sheath material is RoHS-compliant and produces minimal smoke and no halogen-based fumes in fire conditions, making it suitable for public buildings, schools and enclosed spaces where evacuation routes require visibility.\u003c\/p\u003e\n\u003cp\u003eThe purple sheath provides visual identification for audio circuits in mixed-service installations where multiple cable types run in parallel. Each reel handles up to 6A continuous current, covering typical passive speaker loads at 4-8 ohms over runs up to 30m without significant voltage drop. The combined oxygen-free copper and CCA conductor mix gives adequate signal transmission for background music, PA and home cinema applications where premium audiophile-grade pure copper is not specified.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003ePurple LSZH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e2 x 0.75mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (12 x 0.2mmØ Cu + 12 x 0.2mmØ CCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e7mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e6A max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked\u003c\/td\u003e\n\u003ctd\u003e2 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does LSZH mean and why does it matter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLSZH stands for low smoke zero halogen. In a fire, LSZH cable produces minimal smoke and no halogen-based toxic fumes, maintaining visibility in evacuation routes and reducing respiratory hazards. This makes it mandatory or strongly recommended in public buildings, schools, hospitals and multi-occupancy residential installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between oxygen-free copper and CCA conductors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOxygen-free copper has higher conductivity and lower resistance than CCA (copper-clad aluminium). The Mercury Hi-Flex uses both to balance cost and performance — the oxygen-free copper strands carry the majority of the signal, while CCA adds flexibility and reduces weight. For critical audiophile setups, a pure oxygen-free copper cable would offer marginally better performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the 100m supplied?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 100m total is packed as two separate 50m reels. This allows installers to run two separate circuits from a single order, or to use one reel per installation phase without handling a single heavy 100m drum.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat speaker impedance and cable length is this suitable for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt 0.75mm² CSA, this cable suits passive speakers at 4-8 ohms over runs up to 30m without significant voltage drop affecting speaker performance. For longer runs or lower-impedance speakers, a larger CSA cable would be recommended.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313514176779,"sku":"807.096UK","price":68.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/807096UK_LD1_1d752c50-3e82-45e9-88b4-eb6bea9403c1.jpg?v=1715194797","url":"https:\/\/niori.co.uk\/products\/mercury-hi-flex-lszh-speaker-cable-2-x-0-75mm-purple-100m","provider":"Niori","version":"1.0","type":"link"}
