1. Low Loss: No-load losses are reduced by 15%-20% compared to the national standard GB64511-2008, and load losses are reduced by 5% compared to the national standard.

2. Low Noise: The self-cooling noise level is below 60dB, which is nearly 20dB lower than the national standard. Special noise level requirements can be customized upon request.

3. Low Partial Discharge: The entire production process of 110kV products is dust-free, with all internal metal and insulation components rounded, and partial discharge levels controlled below 100pc.

Strong Short-Circuit Capability: The 110kV transformer is certified for strong short-circuit resistance and high reliability.

4. Aesthetic Appearance: Fully polished and rust-free, with powder electrostatic spray paint achieving a home appliance finish, and wide-sheet fin-type radiators.

5. Leak-Proof: All sealing components are made of acrylic materials and utilize one-time molding technology with no interfaces.

Structural Features: NOMEX Insulation + Transformer Insulation Oil

1. High-Temperature Resistance for Enhanced Safety: Can operate continuously at 100% load in an ambient temperature of 40°C; on average, the continuous load rating is 20% higher than conventional oil-immersed transformers at the same temperature.

2. Low Loss for Greater Energy Efficiency: Achieves 20% energy savings compared to ordinary oil-immersed transformers.

3. Maintenance-Free for Improved Environmental Friendliness: Sealing components have the same lifespan as the transformer, resulting in 20% energy savings compared to regular transformers.

Notice:
1. The capacities of the high, medium, and low voltage windings are allocated as (100/100/100)%.
2. The vector group can be YNd11y10 as required.
3. The medium voltage can be chosen to differ from the values in the table or from the tapping points according to user requirements.
4. The maximum current tapping is at the -5% tapping position.
