Power Plant Transformers
Main and auxiliary transformers for power stations.
A power plant transformer must run continuously at high load, withstand high short-circuit forces and keep losses low. We supply oil-immersed power transformers from 35 to 220 kV for step-up and plant distribution, and cast-resin dry-type transformers for indoor auxiliary supply.
Two 25,000 kVA transformers delivered to the Zhangjiagang Guoxin Shazhou Power Plant.
What We Supply
Oil-immersed power transformers, 35–220 kV
Main transformers for power stations
Dry-type transformers for auxiliary supply
References include the Shazhou Power Plant in Jiangsu and a power station main transformer project.
How We Deliver Your Project
Every Yuantong project follows the same controlled process, from technical review to delivery.
01
Requirements & Design
We review capacity, voltage, standard and site conditions, then complete the electrical design with computerized design software and 3D structural modelling.
02
Manufacturing
Cores, coils and assemblies are produced in our Hai'an, Jiangsu factory, including silicon steel cutting, coil winding, vacuum casting and drying.
03
Factory Testing
Every unit is tested in our test hall and receives 100% inspection of appearance and function before release.
04
Packing & Delivery
Units are packed in export wooden cases and delivered by road in China or shipped by sea from Shanghai.
Standards & Quality
Our transformers are designed and built to international and Chinese national (GB) standards as specified by the customer. Our management systems are certified to ISO 9001, ISO 14001 and ISO 45001, and our low-voltage products hold CE attestation of conformity under the Low Voltage and EMC directives.
