Medium Voltage Reeling Cable with Optical Fibre High Speed, High Pull & Torsion Resistant (N)TSCGEWÖU + LWL VDE 0250

Product Overview

The Medium Voltage Reeling Cable with Optical Fibre (N)TSCGEWÖU + LWL is a high-performance power and data transmission cable engineered for extreme dynamic applications. Designed for high-speed movement, high tensile load, and severe torsional stress, it is specifically optimized for monospiral reeling systems (end feed and centre feed) used in cranes, mining equipment, and heavy-duty industrial machinery.

This cable integrates medium voltage power conductors and optical fibre (FO) elements, enabling simultaneous electrical power supply and high-speed data communication in one robust cable system.

It is suitable for demanding environments where continuous motion, mechanical stress, and real-time data transmission are required.
