What is the difference between the OL and 2OL sheath configurations?

The OL version features a single-layer polyolefin sheath, providing basic mechanical and environmental protection, while the 2OL version incorporates a double-layer polyolefin sheath system. The double-sheathed construction offers increased abrasion resistance, improved durability in harsh installation conditions, and enhanced protection against moisture and chemical exposure. Both configurations retain the halogen-free, flame-retardant properties defined by IEC 60502-1.
