Medium Voltage Flat Cable with Optical Fibers

PROTOLON(FL)-LWL (N)TSKCGEWOEU with fiber optics MV Reeling Crane cable Prysmian

PROTOLON(FL)-LWL (N)TSFLCGEWOEU 3.6/6 kV

Application: Flat Reeling Crane Cable with Fiber Optic

This medium voltage flexible flat cable is designed for mechanically demanding applications, such as dynamic tensile stresses, frequent directional changes on a single plane, and roller guidance. It is particularly suitable for fast-moving container cranes, cranes, large mobile equipment, and excavators.
