Automotive primary wires like TXL, SXL, and GXL are the most common type of wire used in the automotive industry. They are usually used in engine compartments and circuit breakers. These wires are small and have a smooth outer surface, making them ideal for small applications and for being pulled through wire looms. The most commonly used automotive primary wire used in engine compartments is TXL wire due to its thin wall.

TXL wire is a thin-wall, single-conductor wire with cross-linked polyethylene (XLPE) insulation. It is a primary wire for automotive applications, often used where small outer diameter and lightweight are needed. TXL wire has a 50V voltage rating and a temperature range of -51C to +125C, making it suitable for use in applications exposed to a wide range of temperatures. These wires come in a wide range of gauge sizes and are often available as small as 22 AWG. While TXL wire is very diverse, sometimes a custom wire is needed.

Our Custom TXL Wire Solution

One customer in the automotive industry reached out to Allied Wire and Cable to help design a custom TXL wire. Our custom automotive cable experts worked closely with the customer and were able to design and manufacture a TXL wire that perfectly matched the needs of the application.

For this application, one conductor would not provide enough power. Instead, four thin wall TXL wires with 20 AWG conductors were combined under cross-linked polyethylene (XLPE) insulation. This extra power ensured the longevity of the application. It also had to meet various specifications, including the SAE J-1128 spec. The SAE J-1128 standard covers low voltage primary wires designed for use in electrical systems.

One of the largest customizations for this cable was the colors used. The wires were all insulated with different colors-- red, green, blue, and black. They were then combined under a black jacket. Since each conductor was a different color, the installation process was easier and faster. Allied Wire and Cable is able to add a wide variety of value-added services to our automotive wires. Services like striping, dyeing, and printing can make identifying your automotive cable easier.

From automotive primary wire to battery cables and speaker wire, Allied Wire and Cable is your expert for custom automotive cable. If you are looking for a custom wire or cable that requires more power or different colors than standard cable, Allied Wire and Cable can help. No customizations are too small or too big for our custom cable experts. To get in touch with one of our knowledgeable sales representatives, visit our Custom Cable Design Center!
