Packaging & Shipping
1 The voltage transformers are packing with wooden packages, and must always stand up according to the direction mark of the packages (except for the 220kV current transformers, they are always packing and transport by lying down).
2 You must remove the wood plates of the top and obverse when you open the package, and then dismantle the 4 pcs M16 bolts which fix in the frame of the package, lift up the voltage transformer vertically and slowly from the package.
3 The clients must check the packages when they receive the voltage transformers, if a package has been broken, they must open the package to check the product together with the forwarder, note down the process and send to the manufacturer.
