Reliable transformer performance starts with consistent manufacturing.
At the Sichuan facility, production and assembly processes are organized around controlled manufacturing procedures and quality inspection requirements.
Depending on the product, manufacturing activities may include raw material inspection, core and coil processing, mechanical assembly, electrical assembly, wiring, component installation, testing, and final inspection before shipment.
For transformer products, particular attention is given to core and winding manufacturing, insulation systems, electrical connections, tank and enclosure construction, accessories, and factory testing.
For prefabricated substations and complete electrical equipment, the manufacturing process also focuses on equipment integration, internal wiring, component configuration, mechanical structure, cable interfaces, and overall assembly quality.
Factory testing and inspection help identify potential issues before equipment leaves the manufacturing facility, reducing unnecessary risks during transportation, installation, and commissioning.
From Transformer Manufacturing to Complete Power Distribution Solutions
The development of the Sichuan facility represents an important step in Yawei’s broader manufacturing strategy.
The objective is to build a production base capable of supporting a wider range of electrical equipment requirements while maintaining the flexibility required by international projects.
