ZTELEC YUGUANG successfully delivered three sets of IEC 60076-compliant 110kV power transformers for national grid infrastructure in the Dominican-Peru region. The project scope covered one 40MVA unit and two 50MVA units, all oil-immersed 110kV power transformers designed to support stable power supply for a local coastal power network.
Meeting a tight project schedule was critical for the customer. ZTELEC completed the entire manufacturing cycle within a 4-month lead time, ensuring the equipment reached site in line with the grid operator's construction timeline.

The project site sits in a coastal city, where high humidity and salt-fog exposure create strict anti-corrosion requirements for outdoor power equipment. ZTELEC addressed these site conditions with three targeted engineering solutions.
The transformer main tank and radiators use a C5-class heavy-duty coating system. This coating resists coastal salt fog and extends equipment service life in a harsh marine atmospheric environment.
The main transformers are fitted with Hitachi custom-manufactured bushings. These bushings guarantee excellent insulation performance and support long-term stable operation under demanding grid conditions.
ZTELEC customized the layout design for the high-voltage bushings and surge arresters. This modified structure matches the on-site construction conditions and real operating scenarios, which simplifies field installation and improves overall operational reliability.
This grid-level power transformer project demonstrates ZTELEC's capability to deliver tailor-made high-voltage power transformers that comply with IEC standards for overseas national power grids. The project team balanced a short delivery cycle, corrosion-resistant design, and site-adapted structural customization throughout execution.
By combining engineering flexibility with strict standard compliance, ZTELEC helped the utility customer build a safe, reliable coastal power transmission infrastructure that can withstand long-term marine environmental exposure.
