A comprehensive engineering guide for procurement managers, maintenance engineers, and electrification project leads who need to replace Prysmian/Draka PROTOMONT-branded reeling, festoon, and vertical hoist cables on port cranes and heavy industrial equipment. This document provides a complete cross-reference matrix mapping every PROTOMONT trade name to its underlying VDE (Verband der Elektrotechnik) standard designation, identifies the exact FeiChun drop-in equivalent for each variant, and specifies the critical installation and commissioning rules — including the No-Twist Spooling Rule, the Slip-Clutch Tension Limit (max 15 N/mm²), and the Multi-Layer Derating Factor — that must be enforced to prevent premature cable failure. Coverage spans low-voltage reeling cables per DIN VDE 0250-814, medium-voltage reeling cables per DIN VDE 0250-813, round and flat festoon cables, vertical hoist cables with Aramid-core reinforcement, and the specialised rubber compounds (5GM5 Neoprene, 3GI3 EPR) that determine the thermal and mechanical service life of each cable type.

NSHTÖU cables, this limit is 15 newtons per square millimeter. This specification is not arbitrary—it is determined through extensive materials testing and represents the maximum sustained tensile stress that the copper conductors and the surrounding insulation can endure without permanent plastic deformation or rupture. When a cable is subjected to tension exceeding this limit, the copper conductors begin to yield, permanently elongating and losing mechanical strength. The insulation, which is bonded to the conductors, separates from them as the conductors stretch. The result is a cable that may appear to function electrically but is mechanically compromised and unsafe for continued operation.

Deep underground mining operations depend on sophisticated systems for moving workers, equipment, and materials between the surface and mining zones that may be hundreds of meters below ground level. One of the most critical systems in these operations is the basket or cage suspension system that safely lowers and raises workers and cargo through vertical mine shafts. These systems rely on flexible (N)SHTÖU cables to deliver electrical power for lighting, ventilation, and communication equipment in the basket, while the mechanical support for the basket itself is provided by separate wire ropes or cables. The electrical cables must be suspended alongside the main support ropes, and this suspension relies on devices called mesh grips — specialized clamping devices that gently but firmly grip the cable without damaging its insulation or internal conductors.
