❓ Frequently Asked Questions
What is the insulation class of dry-type transformers, and why does it matter?
Dry-type transformers typically achieve F-class or H-class insulation, meaning they can withstand operating temperatures up to 155°C and 180°C respectively. Higher insulation class translates to greater overload tolerance, longer service life, and safer operation in high-temperature or harsh environments.
Why are dry-type transformers preferred for high-rise buildings and data centers?
Dry-type transformers contain no flammable oil, which completely eliminates the risk of oil leakage and fire. This makes them ideal for fire safety-critical environments such as high-rise buildings, data centers, hospitals, and underground rail transit systems where fire regulations are strictly enforced.
How do SCB13 and SCB14 differ in terms of energy efficiency?
The SCB13 meets China's National Energy Efficiency Standard at Level 2, offering good energy performance suitable for most commercial and industrial applications. The SCB14 achieves the higher Level 1 standard, featuring even lower no-load losses and higher overall efficiency, making it the optimal choice for projects with strict energy-saving requirements.
Are dry-type transformers truly maintenance-free?
Yes. Unlike oil-immersed transformers that require periodic oil testing, oil filtering, and replacement, dry-type transformers have no liquid insulation medium. This eliminates the need for oil-related maintenance tasks, significantly reducing long-term operating costs and downtime.
Can dry-type transformers be installed directly at the load center?
Absolutely. Their compact structure and flexible installation design allow dry-type transformers to be placed directly at or near the load center. This proximity significantly reduces transmission line length, thereby minimizing line losses and improving overall system efficiency.
What environmental conditions are dry-type transformers suitable for?
Thanks to their vacuum-cast insulation with moisture-proof, dust-proof, and flame-retardant properties, dry-type transformers are well-suited for a wide range of harsh environments — including high humidity, dusty industrial sites, and locations with strict fire safety regulations — ensuring reliable long-term performance.
