GAALFLEX® VFD EMV-FC 3GSEGCY features unprecedented dual-screen architecture: (a) internal dual red copper tape shielding (16 mm² for ≤120 mm² conductors, 25 mm² for >120 mm²) for electromagnetic field containment, and (b) external concentric overall copper screen (red copper wires + helical copper tape, ~0.5 × conductor cross-section electrical) for comprehensive fault protection and ground continuity.
4. Class 2 Stranded Conductors: Large Industrial Motor Applications (35–240 mm²)
GAALFLEX® VFD EMV-FC 3GSEGCY employs Class 2 stranded (bunched, multi-layer) red copper conductors per IEC 60228, sized 35–240 mm² enabling complete large industrial motor spectrum from 100+ kW through 1+ MW frequency converter driven systems with reduced conductor flexibility suitable for fixed industrial installation.
5. EMC-Optimized RFI Shielding: DIN EN 55011/DIN VDE 0875 Classes A1/B1 Compliance
GAALFLEX® VFD EMV-FC 3GSEGCY is EMC-optimized for frequency converter operation per DIN EN 55011 / DIN VDE 0875 Part 11, meeting Classes A1 (industrial electromagnetic environment) and B1 (special requirements), ensuring compatibility with modern variable frequency drive systems and preventing conducted/radiated emissions.
6. Explosion Hazard & Underground Burial: ATEX Certification & Direct Ground Installation
GAALFLEX® VFD EMV-FC 3GSEGCY is certified for ATEX explosion hazard areas and approved for direct underground burial, enabling installation in mining, chemical processing, petrochemical facilities, and subsurface utility networks without additional conduit protection.
7. Dual Voltage Flexibility: 3.6/6 kV (21 kV test) & 6/10 kV (29 kV test) Grid Integration
GAALFLEX® VFD EMV-FC 3GSEGCY offers dual voltage rating enabling seamless integration with either 3-phase 3.6/6 kV distribution systems (common in European industrial facilities) or 6/10 kV industrial grids, providing single product solution for diverse industrial infrastructure.
