Top G71 Series High Voltage Frequency Converter Manufacturers in China

The G71 is designed for high reliability. In many configurations, the system can automatically bypass a faulty power unit and continue to operate at a reduced capacity, preventing a total shutdown of your critical process.

Fiber optics are completely immune to the high electromagnetic interference (EMI) found in high-voltage environments. This ensures flawless, high-speed communication and maximum system stability.

The switching cabinet provides a way to bypass the frequency converter and run the motor directly from the grid. This is a critical feature for planned maintenance or as a backup to ensure maximum plant uptime.

Liquid cooling is recommended for installations with very high ambient temperatures, limited ventilation, or in environments with significant airborne dust or corrosive elements, as it offers a sealed and more efficient cooling solution.

It connects directly to the 6kV or 10kV grid and motor, eliminating the need for large, expensive, and inefficient step-down/step-up transformers that would be required for a low-voltage drive system.

The modular cabinet design allows the transformer, control, and power cabinets to be transported as separate, manageable units, often fitting into standard shipping containers for efficient and safe delivery.

Operation is managed through the central control cabinet’s HMI touch screen. This multi-language interface provides real-time monitoring of key data like input/output voltage and current, the status of each power unit, and transformer conditions, presenting a clear system overview.
