Q1: In which sectors are 30kV three-phase oil-immersed transformers primarily used?

A: 30kV three-phase oil-immersed transformers are primarily used in power distribution systems, industrial parks, mining operations, commercial buildings, new energy projects, and urban or rural grid infrastructure, providing users with stable, reliable voltage transformation and power supply.

Q2: What is the rated voltage of the 30kV three-phase oil-immersed transformer?

A: The rated voltage on the high-voltage side is typically 30kV. The low-voltage side configuration depends on customer needs—commonly 0.4kV—but can also be customized according to specific project requirements.

Q3: What cooling method does the 30kV three-phase oil-immersed transformer use?

A: This product utilizes the oil-immersed self-cooling (ONAN) method; the circulation of transformer oil dissipates heat generated during operation, thereby enhancing the equipment's operational stability and service life.Q4: What are the advantages of the 30kV three-phase oil-immersed transformer? The product features a reliable structure, low losses, stable operation, excellent heat dissipation, easy maintenance, and a long service life, making it capable of meeting the demands of long-term, continuous operation.

Q4: Can the capacity of the 30kV three-phase oil-immersed transformer be customized?

A: Yes. The capacity can be customized according to specific project requirements; common capacities include 500kVA, 630kVA, 800kVA, 1000kVA, 1250kVA, 1600kVA, etc.

Q5: Which standards does the 30kV three-phase oil-immersed transformer comply with?

A: The product is designed and manufactured in accordance with international standards such as IEC 60076. Additionally, certifications and configuration solutions can be provided to meet the power standards of different countries and regions.

Q6: Can the 30kV three-phase oil-immersed transformer be used in new energy projects?

A: Yes. This product is widely used in photovoltaic power plants, wind power projects, and power systems supporting new energy, enabling stable voltage step-up and reliable grid-connected operation.

Q7: What is the service life of the 30kV three-phase oil-immersed transformer?

A: Under normal operating conditions and with regular maintenance, the 30kV three-phase oil-immersed transformer has a long service life, typically capable of stable operation for over 25 years.
