Six Main Types of Automotive Primary Wires

Automotive primary lines are used in various applications like wiring a battery harness, general circuitry, and specialized electric connections. Different connections have varying demands, hence the need for a variety of automotive wires. Automotive leads are segregated according to the temperatures they can withstand. These wires are constructed using various materials to ensure compatibility across applications. 6 Main types of Automotive Primary WiresAutomotive primary wires are primarily divided in the following types:
GPT: These lines are manufactured to be compatible with SAE J-1128 specific circuitry.
Temperature Range: -40 °C – 90 °C

TWP: These cords feature smaller diameters and are lighter than other wires. They can also be manufactured without any lead.
Temperature Range: -40 °C – 90 °C

HDT: It stands for heavy duty thermoplastic. It consists of a protective layer that allows it to be used in harsh environments.
Temperature Range: -40 °C – 105 °C

GXL: These cables are used in general circuitry and ground wiring of batteries. They are used in high temperature SAE J-1128 specific circuitry.
Temperature Range: -40 °C – 155 °C

SXL: Like GXL wires, these wires are also used in general circuitry and ground wiring of batteries.
Temperature Range: -40 °C – 155 °C

TXL: This is a low tension high temperature wire. It is light and features a small diameter.
Temperature Range: -40 °C – 155 °C
Customization of WiresIf you are unable to find the right type of automotive primary wire for your application from the list mentioned above, you will benefit from customizing your wire. A manufacturer with customization capabilities will be able to understand your application requirements and design a product that meets those specific needs. Please remember that the cost for designing and manufacturing a custom product is higher than buying a product in stock. The reason for this lies in economies of scale. A product being manufactured in bulk will be priced lower compared to one manufactured in limited quantities. This is because the cost of the raw materials, employee, or consultant fees, designing, and other factors influencing the overall cost of a product will also be lower.Depending on your application, you can opt for standard or customized wires. Your manufacturer or supplier will be able to guide you regarding the same. You can also conduct tests with sample products to check the compatibility of the product and application. You can put the wires through various stress, temperature, and other relevant tests. These steps will allow you to check the performance of the product and choose one that is compatible with your application.
