SXL

SXL automotive wire with heavy-wall XLPE insulation, rated -40°C to +125°C. Delivers heat, oil, and abrasion resistance for engine, battery, and heavy-duty vehicle wiring.

SXL Automotive Wire – Heavy-Wall XLPE Insulated Cable for High-Temperature Vehicle Applications

SXL automotive wire is a heavy-wall insulated wire constructed with Cross-Linked Polyethylene (XLPE), engineered for high-temperature and harsh automotive environments. With a temperature rating of -40°C to +125°C and voltage up to 60V, it provides robust protection for power and signal circuits in engine compartments, battery lines, and control systems.

Its thick XLPE insulation resists heat, oil, abrasion, and chemicals while maintaining flexibility, making it suitable for heavy-duty vehicle platforms, agricultural equipment, and industrial transport systems. SXL wire meets SAE J1128 and OEM specifications including Ford M1L-85B and Chrysler MS-5919.
