KEY - 3B&S (26mm²) Red Single Core Automotive Cable - Australian Made - 100m Roll

100 Metre Roll of KEY 3B&S (26mm²) Red Single Core Automotive Cable for High-Current 12V, 24V and 48V Wiring

Heavy-Duty Single Core Cable for Positive and High-Current Circuits

This 100-metre roll of 3B&S (26mm²) red single core automotive cable is manufactured by KEY, an Australian cable maker based in South Australia. The 99.9% OFHC (Oxygen Free High Conductivity) copper conductor (364/0.30 stranding) keeps resistance low over long cable runs, which helps hold voltage steady at the load in high-current circuits such as dual-battery interconnects, DC-DC chargers and inverter feeds.

The core is insulated in V90HT PVC rated to 90°C, with a red outer sheath for clear positive-circuit identification alongside the black-jacket version of the same cable. It carries a 170A current rating and a 120V DC maximum rating, making it suitable for 12V, 24V and 48V low-voltage systems.

Supplied as a continuous 100-metre roll, this length suits auto electricians, installers and workshops running multiple dual-battery, inverter or solar projects without joins.
