What is GXL Automotive Wire?

Our GXL wire is a thin wall primary wire that features a stranded bare copper conductor and cross-linked polyethylene (XLPE) insulation. This type of primary wire is ideal for use in engine compartments and other automotive applications where high-temperature performance is required. It is most commonly found in tractors and trailers. However, it is also often found in passenger cars and boats.

The stranded conductor and thin wall insulation in this wire make it extremely flexible and suitable for small spaces. Cross-linked Polyethylene is an extremely durable material that provides resistance to abrasion, high temperatures, and most solvents. Allied Wire and Cable offers GXL wire from 20 AWG to 8 AWG in a variety of spool sizes, so we're sure to have the wire you need.

GXL Wire Specifications

This wire has a temperature range of -40˚C to 125˚C, making it suitable for use in colder temperatures as well. It has a recommended voltage rating of 50V. This wire is ideally suited for engine compartments. The insulation is thin so it fits in small spaces, but it's thick enough to protect the wire from high temperatures and environmental factors. Allied Wire and Cable's GXL Wire meets SAE-J-1128, Ford M1L-85B, and Chrysler MS-8900 specifications.

GXL vs SXL vs TXL Primary Wire

GXL, SXL, and TXL are all types of cross-linked automotive primary wires. These wires all have high-temperature resistance and great flexibility. The main difference between these wires is their insulation thickness and Ford and Chrysler approvals. TXL wire has thinner insulation than GXL, and SXL has thicker insulation. You can learn more about the differences between TXL and GXL wire here.
