What Is SXL Wire?

SXL wire is a type of automotive primary wire made with cross-linked polyethylene insulation, giving it superior heat, moisture, and abrasion resistance compared to standard PVC primary wire. When customers search “what is SXL wire”, the answer is simple: it’s a rugged, high-temperature wire designed for automotive, truck, marine, and industrial equipment where reliability under stress is essential. This makes it ideal for under-hood applications, engine compartments, and high-heat wiring routes.

SXL Wire Specifications

Our SXL wire specifications include a 60-volt rating, high-temperature resistance up to 125°C, and flexible stranded copper conductors for easy installation. The tough XLPE insulation resists oils, chemicals, and vibration, making this SXL automotive wire suitable for both OEM and aftermarket electrical systems. Available in a range of gauges and colors, SXL cable supports both small repairs and large-scale wiring projects.

SXL vs. GXL Wire

Both SXL and GXL are cross-linked automotive wires, but they differ in insulation thickness and durability. SXL wire features a thicker XLPE insulation, offering enhanced abrasion resistance and higher mechanical strength, making it ideal for heavy-duty, off-road, and industrial equipment. GXL wire provides a thinner wall for lighter, more flexible applications while still offering high-temperature performance. When considering SXL vs. GXL wire, SXL is the best option for rugged environments, while GXL is suitable for standard automotive circuits needing flexibility.
