What Types of Insulation Are on Automotive Wire?

There are two main categories of automotive wire: PVC and cross-linked. The biggest difference between the two categories is temperature range. Cross-linked automotive wire can withstand much higher temperatures than PVC automotive wire.

The three main types of PVC automotive wire are:

  1. GPT: used for general circuit wiring and rated to 80 degrees Celsius
  2. TWP: lead-free, thin-wall automotive wire rated to 105 degrees Celsius
  3. HDT: heavy-wall automotive wiring rated to 80 degrees Celsius

PVC is insulation is extruded and created by heating PVC and then extruding it through a die on the stranding. This insulation can be melted with a heat source, changing the form.

The three most common types of cross-linked automotive wire are:

  1. GXL: thin wall, most common type, works with most standard automotive connectors, rated to 125 degrees Celsius
  2. SXL: standard wall, rated to 125 degrees Celsius
  3. TXL: extra-thin wall, best for applications requiring minimal size and weight, rated to 125 degrees Celsius

Cross-linked insulation is created by extruding the material through a tube, under heat and pressure, in order to "cross-link," or change the molecules of, insulation to another state.
