This project uses 2,000 square meters of 600mm wide and 80mm thick four-sided tongue-and-groove rock wool sandwich wall panels. The use of aluminum-magnesium-manganese panels can effectively resist power system failures caused by natural disasters and avoid large losses. It has extremely high bending load-bearing capacity, good earthquake resistance and impact resistance, sound insulation performance, and can protect the smooth operation of the power grid to a limited extent.
