Each core contains 20 copper strands and 60 CCA strands at 0.12mm diameter, giving a combined cross-sectional area of 0.94mm² per core and a maximum current rating of 6A. The clear sheath shows the conductors inside, with one core marked red for polarity identification during installation.\u003c\/p\u003e\n\u003cp\u003eDesigned for permanent speaker installation in commercial audio systems, distributed 100V line systems, home cinema runs and whole-house audio, the cable offers flexibility for routing through wall cavities, ceiling voids and conduit. The 100m reel length suits runs of up to 50m per speaker pair with minimal waste, or shorter runs across multiple zones from a single reel. The 4.2 x 8.2mm profile fits standard cable clips and trunking.\u003c\/p\u003e\n\u003cp\u003eThe copper\/CCA blend balances conductivity with weight and cost for long cable runs where pure copper would be prohibitively heavy or expensive. CCA provides 61% of the conductivity of pure copper at significantly lower cost and weight per metre, making it viable for domestic and light commercial installations where signal loss over typical run lengths remains within acceptable limits. The transparent sheath allows visual inspection of conductor integrity without stripping the cable.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSheath\u003c\/td\u003e\n\u003ctd\u003eClear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePolarity\u003c\/td\u003e\n\u003ctd\u003eRed\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\u003eConductor\u003c\/td\u003e\n\u003ctd\u003eCopper\/Copper Clad Aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003ctd\u003e0.94mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStrands\u003c\/td\u003e\n\u003ctd\u003e2 x (20 x 0.12mmØCu + 60 x 0.12mmØCCA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4.2 x 8.2mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePacked quantity\u003c\/td\u003e\n\u003ctd\u003e8 reels\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\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the maximum run length for this cable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFor passive speaker systems at 8 ohms, runs up to 15m per speaker maintain acceptable signal loss. For 100V line distributed systems, runs of 30-50m are typical. Longer runs may require a higher CSA cable to avoid audible signal degradation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the red polarity marking indicate?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOne core is marked red along its length to identify positive polarity. This ensures consistent phasing across multiple speakers — all red cores connect to positive terminals, all unmarked cores to negative. Reversed polarity between speakers causes phase cancellation and weak bass response.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs CCA suitable for all speaker installations?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCopper-clad aluminium provides 61% of pure copper's conductivity, making it suitable for domestic installations, background music systems and light commercial applications where run lengths are moderate.
