It is made of hot-dip galvanized and sprayed materials, which has good anti-rust and anti-corrosion performance, and can resist the erosion of acid and alkali environments. Its special design includes a double-sided 6-row aluminium profile cold air duct and a rear central aisle cold air duct, as well as a front-mounted central aisle-type negative pressure exhaust system, which meets the design requirements of electrical clearance and creepage distance.

Reliable laser welding technology is used between the pole and the deflector to ensure the stability and reliability of the connection.

An insulating sheet is also installed between the cells to further improve the insulation level and accurately detect the voltage and temperature of the cells.
