Battery and starter circuits work at 12, 24 or 48 volts, and that low voltage changes how the cable is chosen. The currents are large, a starter can pull several hundred amperes for a few seconds, and at such a low supply voltage even a small voltage drop is a large share of the total. A run that is too thin or too long leaves the load starved, so these cables are kept short and generous in section.
Construction and standards
APAR battery cables use a stranded conductor for flexibility, insulated with electron-beam irradiated PVC or polyolefin, which cross-links the compound and makes the cable tough enough to install and route easily. The grade, size, voltage and length are printed on the sheath, so a cable can be identified without stripping it. They are made and tested to IS 2465, with automotive approvals to SAE J1128, JASO D 611, JASO D 618 and ISO 6722-1.
Range
Single-core, twin and multi-core constructions are offered from 1.5 and 2.5 sq mm and from 4 sq mm up to 240 sq mm, and cables with 8000-series flexible aluminium conductor are available where weight matters. The sizes serve everything from light vehicles to heavy commercial vehicles and stationary battery banks.
