How they sell

Builds to order, so a purchase order buys a production slot rather than a unit on a shelf.

In practice that means a purchase order is a place in a queue. Ask for the lead time from purchase order in writing, and ask whether the quoted date is a ship date or a production start. Those are not the same thing and quotes rarely say which.

Where they fit on a job

Federal work needs TAA eligible origin, so confirm the country of manufacture on the specific unit rather than assuming from the brand. Many brands build in several countries.

Common questions

Does JZP make pad mounted transformers for the US

Yes. JZP lists three phase pad mounts for North American voltages such as 34.5 kV to 480Y/277, and its operating company holds UL file XPLH.E541627 for liquid filled pad mounted transformers. Confirm the listing covers the exact unit you are quoted.

Where are JZP transformers made

In Jiangsu, China. The group is headquartered in Suzhou.

Is Jiezou Power the same company as JZP

Yes. The group uses both names, JZP Group and Jiezou Power, and its UL listing is held by JZPE Power Transformer (Jiangsu).

Are JZP transformers TAA eligible

No. China is not a designated country under the Trade Agreements Act, so units built there are not TAA eligible for federal contracts that require it.
