0.6/1kV reeling cable

NSHTÖU-J 24G2.5 multi-core cable is the global industry standard for ship-to-shore (STS) crane spreader basket control and power delivery because it uniquely solves the corkscrew effect problem that renders ordinary flexible cables unusable in vertical lift spreader systems. The cable’s continuous ampacity is approximately 15 amperes when operating under actual high-speed reeling conditions at tropical port ambient temperatures and accounting for bundling of multiple control and power conductors within the spreader basket. This 15-ampere rating emerges from the cable’s reference capacity of approximately 30 amperes per conductor in free air at 30°C, derated through application of VDE 0298-4 bundling factors (approximately 0.45–0.50) to account for the 24-core configuration and multiple derating factors inherent to spreader basket duty. More significantly than mere ampacity, the NSHTÖU-J design incorporates an advanced helical anti-torsion braid combined with specially formulated elastomer compounds that resist the rotational stresses created when spreader baskets spin or oscillate during wind events or uneven load distribution on the vessel deck. Older-generation cables lacked this anti-torsion engineering and failed catastrophically when exposed to the twisting stresses of spreader operation, resulting in control signal loss, dropped containers, and potential injury to dock workers below. Today, the NSHTÖU-J has become the de facto standard across every major container port globally—from Singapore and Rotterdam to Los Angeles and Shanghai—because its reliability in preventing corkscrew failure has proven itself across decades of service and millions of container movements.
