❓ Frequently Asked Questions
Q
What makes dry-type transformers safer than oil-immersed transformers?
A
Dry-type transformers completely eliminate the use of insulating oil, which removes the risk of oil leakage and fire hazards. Their flame-retardant, vacuum-cast insulation (F/H-class) makes them inherently safer for use in fire-sensitive locations such as hospitals, data centers, and high-rise buildings.
Q
What insulation class do these dry-type transformers achieve?
A
These transformers typically achieve F-class or H-class insulation, formed through a vacuum casting process using high-purity copper coils. This ensures excellent thermal stability, moisture resistance, and long-term reliability even in harsh operating environments.
Q
What is the difference between the SCB13 and SCB14 models?
A
The SCB13 meets China's National Energy Efficiency Standard at Level 2, while the SCB14 achieves the highest National Energy Efficiency Standard (Level 1). The SCB14 offers superior energy-saving performance, making it the preferred choice for projects with strict energy efficiency requirements.
Q
Are dry-type transformers suitable for outdoor or harsh environments?
A
Yes. The vacuum-cast insulation structure provides robust moisture-proof, dust-proof, and flame-retardant protection, enabling reliable long-term operation in demanding environments. However, for fully outdoor installations, appropriate enclosure ratings should be confirmed based on the specific site conditions.
Q
Do dry-type transformers require regular maintenance?
A
One of the key advantages of dry-type transformers is their maintenance-free design. Unlike oil-immersed transformers, there is no need for oil sampling, oil replacement, or leak inspections. Routine checks typically only involve visual inspection and cleaning, significantly reducing lifecycle maintenance costs.
Q
How does the compact design of dry-type transformers benefit installation?
A
The compact structure and flexible installation options allow dry-type transformers to be placed directly at load centers within buildings or facilities. This minimizes the length of distribution cables, effectively reducing line losses and improving overall system efficiency — particularly beneficial in space-constrained environments like commercial complexes and data centers.
