GXL wire is an American standard automotive cable primarily used in automotive applications that require minimum diameter and minimum weight. Its conductor is made of twisted soft copper wire that meets ASTM B3 requirements, and the insulation material is cross-linked polyethylene (XLPE). In addition, its rated temperature is 125 ° C, rated voltage is 50V, and operating temperature range is -40 ° C-155 ° C. This type of wire follows the SAE (Society of Automotive Engineers) J1128 standard. When selecting GXL wires, users need to choose the appropriate type and specification of wire according to their actual needs.
