Transformer bushing performance characteristics

Transformer bushings are one of the essential components used for insulating and protecting transformers. Their performance is typically evaluated based on several aspects:

1. Insulation Performance: Transformer bushings must possess excellent insulation properties to effectively isolate high-voltage components within electrical equipment, preventing current leakage and breakdown. Common insulation materials include insulating paper, insulating resin, polymers, etc., with insulation performance meeting relevant international or industry standards.

2. Heat Resistance: Since transformers generate high temperatures during operation, transformer bushings need to demonstrate good heat resistance, allowing them to operate stably for extended periods in high-temperature environments without failure.

3. Corrosion Resistance: Transformer bushings are often exposed to harsh environments, susceptible to moisture, chemical substances, or other corrosive media. Therefore, they require good corrosion resistance to ensure long-term stable operation.

4. Mechanical Strength: Transformer bushings need to have a certain level of mechanical strength to withstand external forces such as compression, tension, and impact, protecting the internal transformer equipment from damage.

5. Fire Resistance:Transformer bushings typically need to exhibit a certain level of fire resistance to prevent the spread of fire in case of a fire, ensuring the safety of surrounding equipment and the environment.

6. Environmental Performance:Modern transformer bushings usually need to comply with environmental requirements, preferably manufactured with non-hazardous materials to reduce pollution to the environment and minimize impact on human health.

7. Convenience of Installation and Maintenance: The design of transformer bushings should consider the convenience of installation and maintenance, allowing for easy installation, inspection, and replacement, thereby improving equipment reliability and operational efficiency.

In summary, excellent transformer bushings should demonstrate outstanding performance in insulation, heat resistance, corrosion resistance, mechanical strength, fire resistance, environmental friendliness, and ease of installation and maintenance, ensuring the safe and stable operation of transformer equipment.
