GNEE 750 kVA Transformer Product Line
As a leading 750 kVA transformer manufacturer, we offer three main configurations, each tailored to specific installation environments and safety requirements.
750 kVA Dry-Type Transformer
The safest choice for indoor and sensitive locations. These units utilize air and resin/VPI insulation, eliminating the use of flammable liquids and simplifying maintenance.
Key Features: Cast resin or VPI systems (Class F/H insulation), low partial discharge (< 10 pC), moisture-proof design.
Ideal Applications: Hospitals, data centers, high-rise commercial buildings and metro stations.
750 kVA Oil-Immersed Distribution Transformer
The most common choice for outdoor substations and industrial plants, delivering exceptional cooling efficiency and service life.
Technical Highlights: Filled with mineral oil or biodegradable ester oil (eco-friendly option), sealed or conservator tank options, equipped with critical monitoring sensors (temperature, pressure).
Common Applications: Industrial manufacturing, utility distribution and renewable energy step-up systems (solar PV plants, wind farms).

Quality and Testing Assurance
Every 750 kVA transformer undergoes rigorous testing-this is what defines the best 750 kVA transformer manufacturer.
Mandatory Factory Tests (per IEC/IEEE Standards):
- Ratio and polarity verification
- Short-circuit impedance and load loss measurement
- Insulation resistance and dielectric strength testing
- Partial discharge and temperature rise testing (critical type tests for reliability)
We offer an optional intelligent monitoring system equipped with IoT sensors that track oil temperature, load and harmonics, providing you with real-time data for predictive maintenance.
