Extended technical guide for port electrical engineers, crane OEMs, ship unloader integrators, and terminal procurement teams covering: the engineering rationale for marine-grade pendant cable specification versus standard industrial pendant cable; detailed deconstruction of the RHEYFLEX-PN construction from conductor stranding through EPR insulation, polyamide strength member, and polychloroprene sheath; chloride-driven copper corrosion fatigue mechanisms at pendant cable terminations; comparative evaluation against H07RN-F (harmonised heavy-duty rubber), RHEYFLEX® 500 -Y- (PVC-insulated control), RHEYCORD® NSHTOEU-J (reeling cable platform), and BUFLEX® DGR (drag-chain rubber cable); 5GM3 versus 5GM5 polychloroprene sheath chemistry analysis; ISO 9227 and IEC 60068-2-52 salt fog test methodology; and FeiChun's FC-RHEYFLEX-PN-M equivalent with FC-FLX™ ultra-fine tinned conductors, aramid hydrolysis-immune strength member, and 5GM5 marine-grade polychloroprene outer sheath.

RHEYFIRM®(RTS) (N)TSCGEWTOEUS OF encodes the cable's entire construction in German VDE convention. N — Normenleitung (standard cable). T — Trommelleitung (drum/reeling cable). S — Starkstrom (power current). C — Geschirmte Adern (screened cores, i.e., semi-conductive layers). G — Gummi-Isolation (rubber insulation). E — EPDM-based insulation compound. W — Wellenschlag (anti-torsion, wave-lay construction). T — Tragfähig (load-bearing, i.e., reinforced with high-tensile braid). O — Ohne Metallmantel (without metallic sheath). E — Elastomer-Außenmantel (elastomer outer sheath). U — Unbewehrt (unarmoured). S — Schlagwetterfest (resistant to explosive atmospheres/heavy-duty). OF — Öl- und Flammwidrig (oil- and flame-resistant enhanced). RTS — Rheyfirm Torsion Spezial (ultra-fine stranding optimised for torsion and high-speed reeling). Each element of this designation corresponds to a specific construction layer examined in the following sections.
