What is GXL Automotive Wire?

GXL is an automotive primary wire and the most common type of cross-linked automotive wire. Notable features of GXL wire include:

  • Temperature range— GXL primary wire is rated from -51˚C to 125˚C. Its ability to hold up against such high temperatures is thanks to its Cross-Linked Polyethylene (XLPE) insulation.
  • Flexibility— Type GXL wire typically features a bare copper conductor and is stranded for great flexibility.
  • Size/Thickness— Type GXL wire has a thin insulation wall. The thin wall allows this automotive wire to fit in small areas.

GXL automotive wire is available in gauge sizes ranging from 20 AWG to 8 AWG. Allied's GXL automotive primary wire meets Ford (M1L-85B) and Chrysler MS-8900) specifications as well as SAE-J-1128.

Applications

With XLPE insulation, GXL automotive wire works particularly well in engine compartments where higher temperature performance is required. GXL wire is most commonly found in tractors and trailers. However, there are many other automotive applications for GXL such as passenger cars and boats.

GXL vs SXL vs TXL Automotive Primary Wire

GXL, SXL, and TXL are all popular types of automotive primary wire. They have many of the same features, including high-temperature ratings and great flexibility. The main difference between type GXL wire and the other cross-linked automotive wires is wall thickness.

Type SXL automotive primary wire has a standard wall thickness, thicker than the insulation on GXL wire. SXL wire is primarily used in engine compartments. Type TXL wire has an extra thin wall thickness thinner than that on GXL wire. The extra-thin wall makes this wire best for applications where space is limited and a lightweight wire is required.

Value-Added Services

The automotive wire can be customized with value-added services to make identification easy. Up to three stripes, also known as tracers, can be added to wires for use in automotive wire harnesses that exceed the standard color code. Jacketing can also be printed with custom text, numbers, or even a company logo.
