Packing and delivery

Yawei Transformer boasts over 30 years of experience in transformer manufacturing and export, making them highly adept in the intricacies of transformer packaging and transportation.

 

In the case of 110KV 230 kV power transformers, with dimensions exceeding three meters in height and weight surpassing 50 tons, it is common practice to disassemble high-voltage bushings, radiators, fans, and other accessories. Subsequently, the transformer body and these removable components are shipped separately.

 

Yawei Transformer employs specialized open-top containers to securely packing the transformer body, while the detachable accessories are meticulously packed in wooden cases, ensuring their safe transport via a separate container.
