On April 28, 2026, two Pad Mounted Transformers manufactured by Tianan Electric were successfully shipped and dispatched to Guatemala for local power grid upgrading and industrial power supply projects.This marks the third consecutive year that our company has supplied Pad Mounted Transformers to Guatemala.
The transformers exported this time are ZGS combined pad mounted transformers, which are compliant with the power grid standards of North America and Central America. Featuring compact structure, low power loss, high reliability, moisture resistance and salt-fog resistance, they can meet the stable power supply demands of Guatemala’s urban power distribution networks, industrial parks and clean energy projects. The transformers were developed and manufactured in-house by our company, with the entire process—from design and production to testing—conducted in strict accordance with ANSI-IEEE standards. The units successfully passed factory acceptance tests and customs inspections, demonstrating efficient operation and long-term stability for engineering applications.

As a major economy in Central America, Guatemala has long been challenged by voltage instability and aging power infrastructure. The local industrial power standard is three-phase 440V, whereas most international equipment operates at 380V. This voltage mismatch has made it difficult for a large number of imported devices to function directly.
The Pad Mounted Transformers supplied in this shipment adopt advanced three-phase conversion technology. Through precise design of the primary and secondary winding turns ratio, they achieve stable voltage step-down from 440V to 380V, with conversion efficiency reaching up to 96%, effectively helping local enterprises reduce energy costs.
Our company has been exporting Pad Mounted Transformers to Guatemala since 2024. The reliable performance of our equipment and responsive customer service have earned high recognition from local clients. Going forward, we plan to further expand cooperation and introduce more clean energy solutions to support Guatemala’s sustainable power development.
