Logistic & Handling
4.1 Shipment
Three phase pad-mounted transformers are shipped hermetically sealed.
4.2 Oil Level
The three phase pad-mounted transformer is filled with oil up to its nominal level from
factory, taking in consideration the ambient temperature at the moment of being filled.
4.3 Hoisting
The transformer is used inside the SUNGROW containerized solution, and it can only be
moved with a crane from the top.
The transformer always must be lifted or held from the four lifting lugs in vertical position
unless it is indicated in any other way.
The lifting lugs are designed to allow the lifting with a maximum angle of 30° between the
sling and the vertical.
When lifting with wider than 30° angles regarding the vertical, an extension bar must be
used for the vertical rising, between the slings.
The cover tank lifting lugs must be used only to raise the cover tank in individual
form. The lifting lugs be used never to lift the complete transformer.
To avoid transformer damage, lift the pad-mounted transformer from the four
lifting lugs.
Do not raise the transformer from drain valves, pipeline connections or radiators.
