Application Scenarios and Advantages

The KSM-S (N)TSCGEWÖU cable system finds its most critical applications in trolley systems and reeling drums where conventional cables would fail under the mechanical stresses involved. These applications demand cables that can withstand not only electrical loads but also significant mechanical forces including dynamic tensile stress, continuous flexing, and multi-plane bending operations.

In container port operations, these cables serve as the vital link between the crane's control systems and the mobile trolley units that traverse the crane structure. The cables must endure constant winding and unwinding on reeling drums whilst maintaining electrical integrity for both power transmission and critical control signals. The dynamic nature of crane operations, with rapid acceleration, deceleration, and directional changes, places extraordinary demands on the cable's mechanical properties.

Mobile heavy machinery applications present equally challenging scenarios. Excavators, mobile cranes, and specialised mining equipment require power and control cables that can accommodate the complex movements inherent in their operation. These machines often operate in environments where the cable must flex in multiple planes simultaneously whilst maintaining reliable electrical performance. The KSM-S (N)TSCGEWÖU cable's advanced construction ensures consistent performance under these demanding conditions.

Environmental versatility represents another significant advantage of this cable system.

Key Features That Ensure Performance

The exceptional performance of the KSM-S (N)TSCGEWÖU cable system stems from several key design features that address the specific challenges of reeling cable applications. The anti-torsion braid represents one of the most critical innovations in the cable's construction. This specialised braided element prevents the accumulation of torsional stress that would otherwise cause conventional cables to fail prematurely when subjected to rotational forces during reeling operations.

Weight reduction and diameter optimisation contribute significantly to the cable's performance advantages. The engineering team has achieved substantial reductions in both outer diameter and weight compared to conventional cables of similar electrical capacity. This reduction minimises the mechanical loads on reeling equipment whilst improving handling characteristics and reducing fatigue on support structures. The reduced diameter also allows for more compact reeling drum designs, contributing to overall system efficiency.

High-speed operation capability sets the KSM-S (N)TSCGEWÖU cable apart from conventional alternatives. With maximum operating speeds of up to 180 metres per minute, the cable can accommodate the rapid movements required in modern automated handling systems. This high-speed capability is achieved through careful attention to dynamic balancing, material selection, and construction techniques that minimise heat generation and mechanical stress during rapid reeling operations.

The cable's torsion resistance capability allows for ±50 degrees per metre of torsional movement, providing exceptional flexibility for applications involving complex multi-axis movements. This torsional capability is essential for equipment such as ship-to-shore cranes where the cable must accommodate not only the linear movements of the trolley system but also the rotational movements of the crane structure.

Temperature performance represents another critical aspect of the cable's design. The cable operates reliably across a wide temperature range, from -40°C to +80°C in fixed installations and -25°C to +80°C in moving applications. The conductor temperature rating extends to +90°C, providing additional thermal margin for high-current applications. This temperature performance ensures reliable operation across diverse climatic conditions and industrial environments.

Fire safety characteristics incorporate self-extinguishing and flame-retardant properties according to IEC 60332-1 standards. These safety features are essential in industrial environments where fire risks must be minimised, particularly in applications involving high electrical loads and mechanical equipment that could generate ignition sources.
