600V 2TC Light-SB (600V 2PNCT-SB) cable solves this problem. Built on the same proven JIS C 3327 platform as the unshielded 2TC Light, it adds a critical engineering layer: a tinned copper wire braided combined with cotton yarn shielding that surrounds the insulated conductor bundle. This hybrid metallic/textile braid provides effective EMI containment across the full VFD emission spectrum, preventing radiated noise from escaping power cables and protecting control cables from external interference. Combined with the Kevlar® para-aramid fibre braided tensile reinforcement for mechanical load bearing, the 2TC Light-SB delivers both electromagnetic cleanliness and structural durability in a single cable design purpose-built for the electrical and mechanical demands of modern VFD-controlled port cranes.

crane cable range is a complete family of six specialised cable types engineered to cover every electrical and data connection on modern port cranes — from the simplest yard crane spreader circuit to the most complex automated STS crane with integrated fibre optic networking. The family is divided into two series: the WS-RLIN series for motorised cable reel systems, and the WS-SPRD series for gravity collector basket (festoon basket) systems. Every cable in the range shares a common engineering foundation: JIS C 3327 compliance for rubber-insulated machinery cables, chloroprene rubber (CR) sheathing for oil/ozone/UV resistance, EPR insulation rated to 90°C, and an ambient temperature range of −40°C to +90°C that covers every port environment on earth from arctic to tropical. Within this shared foundation, each cable type is differentiated by its reinforcement system, voltage class, conductor range, and application-specific optimisations.

WS-SPRD-HEXNCT was engineered specifically for this extreme duty class. Its defining characteristic is the HEXNCT enhanced chloroprene rubber sheath — a heavy-duty outer layer with thickness ranging from 4.5 mm to 5.1 mm, representing a 36–38% increase over the standard WS-SPRD-2PNCT's 3.3–3.7 mm sheath. This enhanced sheath provides a dramatically larger abrasion wear allowance at basket carrier contact points, greater resistance to mechanical impact from falling debris, and a more robust barrier against the chemical and environmental hazards of the container crane operating environment.

WS-SPRD-2PNCT was engineered specifically for this unforgiving application. It combines high-core-count construction (30, 36, or 42 cores at 3.5 mm²) to carry the full complement of spreader control and signal circuits in a single cable, steel-wire-stranded conductors for tension resistance under self-weight suspension, chloroprene rubber sheathing for oil, ozone, and UV resistance in coastal port environments, and a cable geometry specifically optimised for the continuous lateral bending and catenary formation cycles unique to gravity collector basket systems. Manufactured to dual standards — JIS C 3327 (rubber-insulated machinery cables) and VDE 0250-813 (flexible cables) — the WS-SPRD-2PNCT represents dedicated engineering for a niche but mission-critical application. A failed spreader basket cable means a stopped crane, a grounded spreader, and halted container operations. There is no redundancy — the cable is the sole electrical lifeline between the crane's trolley and the spreader that grips the containers.

WS-RLIN-3PNCT-OF is the engineering answer to this convergence challenge. It integrates three-phase medium-voltage power conductors (3 × 38–60 mm² at AC 6,600 V) with a dedicated neutral/earth return conductor and six optical fibres housed in individually colour-coded ETFE protective tubes — all within a single Kevlar®-reinforced, chloroprene-sheathed cable construction. This hybrid design eliminates the need for separate power and fibre optic cables on the reel system, reducing reel complexity, installation time, maintenance burden, and total cable weight, while ensuring perfect synchronisation between power and data paths — because both travel through the same physical cable at all times.

WS-FSTN-3PNCT-SB represents the premium tier of the WALSTOON festoon cable family — a cable engineered for applications where standard 2PNCT construction does not provide sufficient mechanical protection. The critical difference is in the designation: 3PNCT versus 2PNCT. The "3" indicates a three-layer sheathing system that includes a dedicated textile reinforcing layer between the core bundle and the outer sheath — a layer that the standard 2PNCT construction does not have. In practice, this reinforcing layer transforms the cable from a flexible electrical conductor into a mechanically reinforced structure that resists impact damage, crushing forces, abrasion penetration, and tensile stress far beyond the capability of standard 2PNCT cables. When a festoon cable runs through a harsh environment — exposed to falling debris from bulk cargo operations, crushed between moving crane structures, subjected to extreme tensile loading during emergency stops, or dragged across abrasive steel surfaces — the reinforcing layer provides the mechanical margin of safety that prevents cable failure. Combined with the tinned copper shield braid for EMI protection, the WS-FSTN-3PNCT-SB delivers dual-layer protection: electromagnetic shielding for signal integrity, and mechanical reinforcement for physical survivability. This combination makes it the cable of choice for the most demanding festoon system positions — particularly on grab-type ship unloaders, heavy-duty overhead cranes in steel mills and foundries, and any application where the cable is exposed to significant mechanical abuse beyond normal festoon system operation.

Festoon cables on port gantry cranes and ship unloaders endure some of the most punishing operating conditions in industrial cable engineering. Every time the crane trolley travels along its rail, the festoon cable is dragged, flexed, accelerated, and decelerated across spans of 100–300 metres. The cable must support its own suspended weight between trolley hangers, absorb dynamic shock loads during emergency stops, withstand continuous wind-induced vibration in exposed coastal environments, and resist the corrosive effects of saltwater spray, UV radiation, and airborne industrial contaminants — all while maintaining electrical continuity and signal integrity for safety-critical crane control systems.

NSHTÖU-J 24G2.5 flexible reeling cable is the globally recognized industry standard for ship-to-shore crane spreader basket vertical lift systems, featuring 24 conductors with 2.5 mm² cross-section per core (one conductor designated green/yellow for grounding/safety) providing approximately 30 amperes current capacity in free-air installation at 30°C ambient, but derating to approximately 15 amperes actual safe continuous current when accounting for the multi-core bundle derating factor of 0.45 to 0.50 and tropical port ambient temperatures. The cable's nominal outer diameter ranges from 28.5 to 32.5 millimeters, with total weight of approximately 1,350 kilograms per kilometer, making it manageable for standard spreader basket spools while maintaining the conductor density necessary for reliable simultaneous power and control signal transmission. The cable features proprietary anti-torsion braid structure embedded between inner and outer sheaths—a critical innovation that provides resistance to ±50° per meter torsional deformation, fundamentally preventing the destructive corkscrew effect that kills ordinary flexible cables within 3 to 6 months of tropical port operation. The cable incorporates Class 5 tinned copper conductors engineered specifically for the fatigue resistance required by continuous 160 meters per minute reeling cycles, EPDM insulation maintaining electrical integrity at the 90°C conductor temperatures that result from high-speed duty cycles in multi-core bundles, 5GM5 elastomer outer sheath providing exceptional resistance to salt-spray corrosion, UV degradation, petroleum-based oils, and mechanical abrasion encountered in global container ports. The cable is rated for 0.6/1.0 kilovolt nominal operation, with dielectric test voltage capability reaching 3 kilovolts, more than adequate for spreader basket control circuits and auxiliary power distribution. Unlike generic "marine-grade" cables or rebranded industrial flexible cables, NSHTÖU-J 24G2.5 is purpose-built to tolerate the combined mechanical, thermal, and environmental stresses unique to STS crane spreader applications—making it not simply the preferred option but the only technically defensible choice for reliability-critical spreader systems operating in high-intensity container port environments.
