Automotive Wires

The Automotive Wires are generally coated with either general purpose thermoplastic (also called GPT or PVC) or cross-link insulation, so named because the insulation material is extruded under heat and pressure, changing the molecular structure and allowing it to withstand higher temperatures. GPT insulation is more cost-efficient, while cross-link insulation is more durable and heat resistant. Colors are used often to identify and trace a wire to a corresponding circuit. One of the best ways to make common repair and construction jobs easier is to assign a different color for each type of automotive wires according to its end use.
