Where longer cable runs or lower impedance loads demand a heavier conductor, the Integrator Series 2 x 2.5mm speaker cable delivers B2ca fire performance with the power handling to match. A maximum conductor resistance of 7.98 Ohms/km is around 40% lower than the 1.5mm² version, allowing runs roughly half as long again before losses become significant. Stranded bare copper to IEC 60228 Class 5 keeps the cable flexible despite the larger cross section. At 7.6mm overall diameter it remains practical to route through containment and ceiling voids on demanding commercial installations.
