GXL vs. TXL vs. SXL: What's the difference?
Choosing the wrong automotive wire can create significant performance issues and even lead to overheating or ignition in certain conditions. With a broad list of options to consider, selecting the appropriate wire can be daunting. Here we break down the subtle differences between three types of single-conductor primary wire with XLPE insulation: GXL, TXL and SXL. Generally speaking, it's the insulation thickness that differentiates these wires:
SXL = Standard
The thickest insulation of the three, SXL is good for high-temp spaces like engine compartments where space is less of a concern
GXL = Thin
This is generally used in high temp spaces where flexibility and reliability are needed. While it is thin walled, there is a thinner option.
TXL = Extra Thin
TXL is the thinnest option, making it ideal when space is at a premium. Extra thin wall also makes it lighter than the others.
