Each conductor has seven 0.18mm copper strands and six 0.18mm CCA strands, giving a combined cross-sectional area of 0.33mm² per core. The white PVC sheath carries a black line along one conductor to identify polarity when terminating.\u003c\/p\u003e\n\u003cp\u003eDesigned for background music systems, small PA installations and domestic hi-fi runs where cable is concealed in walls, under floors or within trunking, the 100m reel suits installation contractors and integrators working on medium-scale projects. The 2.0 x 4.0mm profile fits standard twin cable clips and conduit without excessive bulk. The 2.5A maximum current rating handles amplifier outputs up to approximately 60W RMS at 8 ohms over typical cable runs of 10-20m.\u003c\/p\u003e\n\u003cp\u003eThe mixed copper\/CCA conductor construction balances cost and conductivity. The seven copper strands per core provide the majority of the conductivity, while the six CCA strands add strand count and flexibility without the full material cost of pure copper. The figure 8 profile keeps both conductors parallel throughout the run, reducing the risk of phase mismatch or signal imbalance when cables are cut to length and stripped on-site.\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\u003eLength\u003c\/td\u003e\n\u003ctd\u003e100m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e0.33mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (7 x 0.18mmØCu + 6 x 0.18mmØCCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e2.0 x 4.0mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e12 reels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent\u003c\/td\u003e\n\u003ctd\u003e2.5A max.\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 amplifier power can this cable handle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 2.5A maximum current rating supports amplifier outputs up to approximately 60W RMS at 8 ohms over cable runs of 10-20m.

This marked conductor is typically used as the negative or common terminal, while the unmarked conductor connects to the positive or hot terminal.

Pure copper cable would offer slightly better conductivity but at higher price.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313495433483,"sku":"801.330UK","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/801330UK_LD1_841a274a-da10-4eeb-ab3b-d4433a9017a2.jpg?v=1715194564","url":"https:\/\/niori.co.uk\/products\/mercury-figure-8-speaker-cable-2-x-13-strand-0-33mm-white-black-100m","provider":"Niori","version":"1.0","type":"link"}
