❓ Frequently Asked Questions

What makes dry-type transformers safer than oil-immersed transformers?

Dry-type transformers use solid vacuum-cast insulation instead of flammable transformer oil. This completely eliminates the risk of oil leakage and fire hazards, making them significantly safer for installation in fire safety-critical environments such as hospitals, data centers, and high-rise buildings.

What insulation class do these dry-type transformers achieve?

These transformers typically achieve F-class or H-class insulation, formed through a precision vacuum casting process using high-purity copper coils. This high insulation rating ensures reliable long-term performance even in harsh operating environments with high humidity, dust, or elevated temperatures.

What is the difference between the SCB13 and SCB14 models?

The SCB13 meets China's National Energy Efficiency Standard at Level 2, while the SCB14 achieves the higher Level 1 national energy efficiency rating. The SCB14 is the more energy-efficient option, offering lower no-load and load losses, making it the preferred choice for projects with strict energy-saving requirements.

Do dry-type transformers require regular maintenance?

One of the key advantages of dry-type transformers is their maintenance-free design. Unlike oil-immersed transformers that require periodic oil testing, filtration, and replacement, dry-type units require only routine visual inspections and basic cleaning of ventilation areas, significantly reducing operational costs over their service life.

Where can dry-type transformers be installed?

Thanks to their compact structure, flame-retardant properties, and absence of liquid insulation, dry-type transformers can be installed directly at or near load centers. They are suitable for high-rise buildings, underground rail transit systems, data centers, hospitals, commercial complexes, and industrial or mining facilities — essentially anywhere that requires fire safety compliance or space-efficient power distribution.

How do dry-type transformers contribute to energy savings?

Dry-type transformers deliver lower energy losses compared to conventional oil-immersed types. By allowing direct installation at load centers, they also reduce transmission line losses. Models like the SCB14 meet the highest national energy efficiency standards (Level 1), making them fully aligned with modern green building and energy conservation initiatives.
