Main Features and Advantages
Superior Dielectric Technology: Our capacitor banks utilize premium all-film polypropylene dielectrics impregnated with non-PCB synthetic fluids, delivering exceptional thermal stability and low dielectric losses.
Robust Construction: Featuring stainless steel casings with high-grade porcelain or polymer bushings, these units are designed for extended service life in challenging environments.
Advanced Safety Features: Integrated internal discharge resistors ensure safe maintenance procedures, while inrush current limiting keeps transient currents below 20 times the rated value.
Flexible Configuration Options: Available in both internally fused and externally fused configurations to meet your specific protection requirements.
High Altitude Performance: All products meet demanding requirements for installations up to 4000 meters above sea level.
Practical Applications
Utility Substations: Our units excel in open-rack configurations within outdoor substations, providing bulk reactive power compensation that improves voltage profiles on long transmission lines and increases active power transfer capability.
Heavy Industrial Plants: Perfect for steel mills, mining operations, and petrochemical facilities using Electric Arc Furnaces or large rolling mills. The metal-enclosed designs effectively mitigate voltage flickering and compensate for highly inductive loads.
Renewable Energy Integration: Essential for wind and solar farm collector substations, these banks help meet strict Grid Code requirements and enable Low Voltage Ride Through capabilities during varying generation conditions.
How It Works
The system operates by generating leading reactive current that neutralizes the lagging current produced by inductive loads like motors and transformers. This reactive power compensation brings your power factor closer to unity, reducing total system current and minimizing I²R losses throughout your electrical infrastructure.
When connected to your network, the capacitive reactance provides instantaneous voltage support during peak demand periods. The modular design allows for precise reactive power adjustment, ensuring optimal system performance across varying load conditions.
