How does the Flex RXQ/TXXI differ from a standard N2XH cable?

The Flex RXQ/TXXI retains the fundamental N2XH construction—XLPE insulation and halogen-free sheath—but introduces a highly flexible conductor conforming to IEC 60228 Class 5 fine-wire stranding, rather than the rigid solid or stranded Class 1 or 2 conductors typical of standard N2XH. An advanced, mechanically robust sheath compound is also used, offering superior flexibility and reduced bending radius without sacrificing the flame-retardant and low-smoke properties. This makes it far easier to pull through conduits, cable trays, and tight corners during installation while still achieving full compliance with fire-performance standards like VDE 0482-266-2-1 and EN 50575.
