TXL Wire vs Primary Wire

[Brett Proctor]

Primary wire is a general-purpose automotive wire, while TXL wire is a specific type of cross-linked wire designed for high-temperature and flexible applications.

Overview of Primary Wire​

• Definition: Primary wire is a single conductor wire commonly used in automotive applications. It features stranded copper conductors and is designed for general wiring purposes. It is typically rated for temperatures up to 80ºC (176ºF) or 105ºC (221ºF) depending on the specific type.

Overview of TXL Wire​

• Definition: TXL wire is a type of cross-linked wire that features a thinner insulation wall compared to other types like GXL and SXL. It is designed to withstand higher temperatures (up to 125ºC) and is more flexible, making it ideal for modern vehicles with tight spaces.
