110kV (66kV) Oil-immersed Power Transformer

This independently developed high-temperature resistant transformer features an innovative hybrid insulation system. Utilizing NOMEX® insulation material (Class C) in hotspot areas combined with mineral oil, this design ensures “High Overload, Safe and Reliable” operation throughout its entire lifecycle. It is the ideal solution for users with special demands or for upgrade and capacity expansion projects.

Key Features & Advantages

1. High Overload Capacity & Enhanced Safety

• Core Technology: NOMEX® Insulation + Mineral Oil
• Capable of continuous operation at full load in ambient temperatures up to 40°C.
• Achieves an average of 20% higher continuous load capacity compared to conventional oil-immersed transformers under similar conditions.

2. High Energy Efficiency & Low Losses

• No-load losses are more than 10% lower than the Chinese National Standard GB6451-2015.
• Load losses are more than 5% lower than the national standard.
• Performance complies with the GB20052-2020 energy efficiency standard, offering approximately 20% higher energy savings.

3. Ultra-Low Noise Operation

• Self-cooling noise levels are controlled below 60 dB, nearly 20 dB lower than the national standard.
• Customized ultra-low noise solutions are available upon request.

4. Superior Internal Reliability & Low Partial Discharge

• 110kV production follows strict modern enterprise management in a dust-free environment.
• Internal components are rounded to control electric field concentration.
• Partial discharge is rigorously controlled below 100 pC.

5. Robust Short-Circuit Withstand Strength

• 110kV transformers have passed national-level certification, ensuring no damage from sudden short-circuit incidents.

6. Leak-Proof & Maintenance-Friendly Design

• All seals are made of acrylic material using single-molding technology with no joints.
• We solemnly guarantee no leakage, verified by fluorescent, positive, and negative pressure tests.
• Seals have the same lifespan as the transformer, enabling long-term maintenance-free operation. All materials are recyclable.

7. Aesthetic & Durable Appearance

• Full polishing, derusting, and powder electro-spray painting achieve a home-appliance-grade finish.
• The wide-sheet radiator is sturdy and fade-resistant.
