GXL CROSS-LINKED POLYETHYLENE (XLPE) WIRE Technical Information GPT Wire is available in a variety of different colors, lengths and gauges. Did you know there are different types of wire for different applications? Even though wire may look the same from the outside, there are some important things to be aware of regarding their protective coating. GXL Rated up to 80˚C Rated up to 125˚C PVC GPT wire, which stands for general-purpose thermoplastic wire, is the most inexpensive and the most commonly used wire. GPT/PVC insulation is rated up to 105˚ C, and does not have very good abrasion resistance. Once the temperature gets above the rating, the PVC insulation can reflow and melt off the wire. Other Types of PVC Wire: TWP wire is lead-free, thin wall automotive wire rated to 105°C HDT wire is heavy wall automotive wiring that rates to 80°C GXL GXL wire, also known as a cross-link wire, has a higher temperature rating of 125˚ C. This wire is created by extruding material through a tube, under heat and pressure, in order to cross-link, or change the molecules of, insulation to another state. Which means a broader temperature range from -60°C to 125˚C, no reflow, and better abrasion resistance. This wire works well with most standard automotive connections and is specified for use in engine compartments where high heat resistance is needed. GXL - 500 ft spools are available in the following colors: 10 Gauge BLACK WHITE RED Annealed Bunched Copper Core 12-18 Gauge GREEN BLACK WHITE RED YELLOW BROWN BLUE Color-coded Cross Linked Polyethylene (XLPE) Insulation © 2019 Wurth USA, Inc. 06/2019_Mid Year Review 2
