100kVA 120kVA 150KVA 315kVA 630kVA Neutral Grounding/earthing Transformer Dry Type Power Transformer

Kurumfa

100-630kVA neutral grounding dry-type power transformers with epoxy resin casting offer excellent insulation, fireproof and moisture-proof capabilities. By establishing neutral points, they efficiently connect arc suppression coils or grounding resistors to quickly suppress grid grounding fault currents, enhancing power supply reliability. Suitable for 10kV/35kV distribution networks, data centers, commercial buildings, etc.

 Product Advantages:

Designed to excel in demanding power distribution scenarios, our transformers integrate cutting-edge technology to deliver unmatched reliability and performance.

• Ultra-low Partial Discharge: With a partial discharge level ≤ 10 pC, our transformers minimize electrical stress and insulation degradation, ensuring stable long-term operation and reducing the risk of premature failure.

• Extreme Cold Adaptability: Capable of operating at low temperatures down to -25°C, these transformers maintain reliable performance in harsh environments, making them ideal for cold regions and outdoor installations.

• Superior Performance Classifications: Rated at E3 (Exceptional Aging Resistance), C3 (High Contamination Resistance), and F1 (Low Noise Emission), our products meet the highest industry standards for durability, adaptability, and environmental compatibility.

• Minimal Temperature Rise: Engineered to achieve a low temperature rise (100K - 125K) even under heavy loads, these transformers optimize energy efficiency, extend service life, and reduce maintenance requirements.

• Robust Electrical Tolerance: Designed with high impulse voltage withstand capabilities, our transformers can endure sudden electrical surges and transient overvoltages, while their exceptional short-circuit tolerance ensures safe operation during fault conditions, safeguarding both equipment and power systems.
