It uses hot-dip galvanized and sprayed materials, which provide excellent rust and corrosion resistance and can withstand acidic and alkaline environments. Its special design includes six rows of aluminum profile cold air ducts on both sides and a central cold air duct at the rear, as well as a front central negative pressure exhaust system, meeting the requirements for electrical clearance and creepage distance.

Reliable laser welding technology is used between the pole columns and deflector, ensuring stable and reliable connections. Insulating sheets are also added between individual cells, further enhancing insulation levels and enabling accurate measurement of the voltage and temperature of each cell.
