(N)TSCGEWOEU EMV FC VFD Cable 3.6/6kV – 12/20kV

(N)TSCGEWOEU EMV FC is a medium voltage flexible reeling cable specifically engineered for frequency converter controlled AC drives in mining and heavy industrial applications. Unlike standard (N)TSCGEWOEU, the EMV FC variant features an optimized multi-layer EMC screen design — combining aluminium foil and tinned copper braid — to suppress harmonic interference and meet electromagnetic compatibility requirements per EN 61800-3. Manufactured by TEBAOFLEX to VDE 0250-813, it delivers reliable power transmission in variable frequency drive systems where electrical noise suppression and mechanical durability are equally critical.

(N)TSCGEWOEU EMV FC — TEBAOFLEX Medium Voltage Frequency Converter Cable

The Challenge of Powering VFD Drives in Mining Environments

Frequency converters generate high-frequency harmonics and voltage spikes that can couple into adjacent circuits, cause bearing currents in motors, and interfere with control signals. In open-pit mines and material handling yards where draglines, excavators, and conveyor drives operate on VFD control, a standard MV trailing cable without adequate shielding will radiate electromagnetic interference, leading to drive faults, communication errors, and premature motor insulation failure. The TEBAOFLEX (N)TSCGEWOEU EMV FC is designed specifically to address this. Based on the proven (N)TSCGEWOEU platform, the EMV FC variant adds an optimized EMC shielding system that contains harmonic energy within the cable and prevents interference propagation.

What EMV FC Means

EMV stands for Elektromagnetische Verträglichkeit (EMC), and FC designates Frequency Converter application. The cable is constructed to meet the emission and immunity requirements of EN 61800-3 for variable speed drive systems, while retaining the full mechanical toughness required for mobile mining equipment.

Design Feature What It Does Why It Matters for VFD
EMC Multi-Layer Screen System Aluminium foil tape (100% coverage) + tinned copper braid (≥85% coverage) Provides low-inductance return path for high-frequency harmonics, reducing common-mode currents on drive output
Symmetrical 3+3 Core Geometry 3 power cores + 3 earth cores laid up with earth in interstices Creates balanced electromagnetic field, minimizing differential-mode radiated emissions
Tinned Copper Class FS Conductor Extra-fine stranded tinned copper Superior flex life for reeling; tinning prevents oxidation at drive terminals
Anti-Torsion Polyester Braid Vulcanized polyester thread braid between inner and outer sheath Prevents screen layers from shifting under torsion, maintaining consistent EMC performance
