Advantages of American-style transformer substations

Advantages: Small size and compact structure; fully sealed oil tank, fully insulated design, safe and reliable operation; suitable for both ring network and terminal power supply, convenient operation, and reliable power supply; strong overload capacity and excellent resistance to sudden short circuits; good impact resistance; energy-saving, low loss, not exceeding the new S9 loss value; cable heads can handle 200A load current, with long mechanical and electrical life.

The enclosure undergoes eight pretreatment processes before painting, followed by seven painting and baking processes, demonstrating its meticulous approach to corrosion prevention. Domestically produced American-style transformer enclosures undergo almost no special treatment, basically using acid pickling followed by electrostatic spraying. Some companies even skip acid pickling altogether, and some only apply painting to the outer surface. It's easy to imagine the poor corrosion resistance of their enclosures. Even with electrostatic spraying, dead corners are often left during surface treatment, and it's difficult for electrostatic spraying to apply powder to these untreated areas, inevitably leaving potential for rust.
