TROMMELFLEX (KSM-S) (N)SHTOEU 0.6/1KV Low-Voltage Reeling Cables (Prysmian Cranes Cable)

• These cables are designed for applications where frequent winding and unwinding occur during operation, especially when twisting stress and forced guiding of the cable simultaneously exist. In cases where high dynamic tensile stress is anticipated, such as in high accelerations, the allowable stress limits should be individually determined. These cables are suitable for heavy-duty units like cable drums, hoist systems, conveyor systems, movable motors, traction motors, and agricultural machinery; under high mechanical stress conditions; in dry or humid areas, and outdoors.
