Frequently Asked Questions
What are the primary advantages of a pole-mounted transformer?
Pole-mounted transformers save ground space, are less accessible to the general public (enhancing safety), and provide efficient power distribution for residential and rural areas.
Why is a "fully-sealed" design important?
A fully-sealed design prevents contact between the transformer oil and the outside air. This prevents oxidation and moisture absorption, significantly extending the service life and reducing maintenance requirements.
What capacity range do you offer for single-phase units?
Our standard capacity ranges from 25 kVA up to 500 kVA, catering to various distribution needs.
What winding materials are available?
We offer both high-quality Copper and Aluminum winding options, allowing customers to choose based on their specific weight, cost, and conductivity requirements.
Do these transformers comply with international standards?
Yes, our transformers meet or exceed multiple international standards including ANSI, IEC, and various national GB standards, ensuring global compatibility and reliability.
How does the transformer handle thermal expansion?
The corrugated tank or elastic radiator fins allow for the expansion and contraction of the oil due to temperature changes, maintaining a sealed environment without the need for an external conservator tank.
