The Tech & Specification parameters of our company’s wires are in international unit system, with the unit of millimeter (mm). The following table is a comparison table of American Wire Gauge (AWG) and British Standard Wire Gauge (SWG) for your reference.
The most special dimension can be customized as per the requirements of customers, and the black font is R20 diameter of preferred numbers
