Custom electric opper dry-type grounding transformer 6kV 6.3kV 6.6kV

Dry type grounding transformer Product Description

The dry type grounding transformer (three-phase, for frequency conversion) is a specialized member of industrial earthing transformers, engineered exclusively for frequency conversion systems. It efficiently converts electrical energy, precisely matches the requirements of frequency conversion equipment, reduces harmonic interference, ensures stable frequency conversion operation, and enhances the energy efficiency and reliability of systems relying on industrial earthing transformers.

Industrial earthing transformers Core Advantages

• High Efficiency & Energy Saving：This dry type grounding transformer—a key type of industrial earthing transformers—utilizes an advanced core and optimized winding design, drastically cutting energy loss. With a conversion efficiency of ≥98%, it delivers substantial long-term energy cost savings, maintains stable power output, and effectively boosts the overall efficiency of power systems employing industrial earthing transformers.
• Low Temperature Rise：The dry type grounding transformer features a unique heat-dissipation structure paired with premium insulating materials, ensuring low temperature rise. Heat dissipates rapidly during operation, preventing high-temperature damage to internal components and extending the service life of this critical piece of industrial earthing transformers.
• Low Maintenance: Unlike oil-filled industrial earthing transformers, this dry type grounding transformer requires no regular oil testing or replacement, reducing long-term operational costs and downtime.
• Harmonic Resilience: The optimized winding structure suppresses harmonic interference, ensuring stable grounding protection for frequency conversion systems—a capability many other industrial earthing transformers lack.

Industrial earthing transformers Operation Environment

• Altitude: ≤1000m; derating required above 1000m for both dry type grounding transformer and other industrial earthing transformers.
• Ambient Temperature: -25°C to 55°C
• Relative Humidity: ≤95%
• The installation site must be free of chemical deposits, dust, explosive, or corrosive media that could impair the insulation of the dry type grounding transformer and other industrial earthing transformers.
• The supply voltage should be approximately sinusoidal, with balanced three-phase voltages to ensure stable performance of industrial earthing transformers.
