How many companies can legally supply pad mounted transformers in the US

There are 172 companies holding a UL listing under category XPLH, which covers liquid filled distribution transformers rated over 600 volts. A UL listing is what lets a unit be accepted by an inspector on a US job, so this list is effectively the whole legal supply base.

How many pad mounted transformer manufacturers are TAA eligible

Only 32 of the 172, about 19 percent. TAA eligibility means the country of manufacture is a party to the WTO Government Procurement Agreement or an equivalent trade agreement, which is what federal contracts require. Most of the supply base cannot be used on federal work.

How much of the supply base is Chinese

71 of 172, about 41 percent, are in China. The United States has 39, about 23 percent, and South Korea has 13. Between them those three countries hold about 71 percent of all UL listings in this category.
