SYS type modular transformer (American-style busbox transformer)

The SYS modular transformer places the transformer tank, high-voltage load switch, and protective fuses within the same fuel tank, significantly reducing the size of the equipment. The casing is fully sealed, with concealed high-strength bolts and oil-resistant butyl rubber gaskets used to seal the lid. The casing can withstand long-term pressures of 50kPa. The design carefully considers requirements for waterproofing and preventing condensation. The top cover features a 5% slope to prevent water accumulation. The box doors have three-point locking mechanisms, and the high-voltage compartment can only be opened after the low-voltage compartment has been opened.
