What Is H07RN-F Cable?
The H07RN-F cable is a heavy-duty rubber-insulated and rubber-sheathed flexible cable rated for 450/750V, manufactured to EN 50525-2-21 (formerly VDE 0282-4) standards. The designation breaks down as: H (harmonized), 07 (450/750V), R (rubber insulation – EPR), N (polychloroprene/neoprene sheath), F (fine-stranded flexible conductor, Class 5 per IEC 60228).
As one of the most widely used industrial power cables in the world, H07RN-F is specified across mining, construction, ports, manufacturing, and marine applications where reliability under harsh mechanical and environmental conditions is essential. TEBAOFLEX manufactures H07RN-F cable to full EN 50525 compliance with CE, VDE, and UL certifications. Contact us for a quotation.
