SYS
Combination Transformer - American Box Transformer

Product Introduction
The SYS series combination transformer (American box transformer) is an innovative configuration created by Shuangying Electric with ingenuity
Electrical equipment. It breaks through traditional design concepts by incorporating transformer bodies, high-voltage load switches, and protective devices
The fuse is cleverly placed in the same fuel tank, achieving high integration of the equipment. The box is fully sealed
Sealed structure, using concealed high-strength bolts and oil resistant nitrile rubber gaskets to seal the box cover, can be used for a long time
Capable of withstanding a pressure of 50kPa, effectively isolating external environmental influences. Fully consider waterproofing and waterproofing in the design
Condensation issue, the top cover is designed with a 5% slope to prevent water accumulation, and the box door adopts three-point interlocking, only when opened can it be lowered
The high-voltage interval can only be opened after the interval is pressed, ensuring the safe and stable operation of the equipment in all aspects.
