B. Altitude is not more than ***0m; 
C. Relative humidity: Daily average value should not be more than *5%, while monthly average value should not be more than *0% (**5° C); 
D. Seismic intensity should be not more than 8° ; 
E. Places without fire, explosion risk, serious pollution, chemical corrosion and violent vibration. 

IV. Design & Structure
The switch cabinet is metal-clad. Its structure design accords with the standards GB******1, IEC**8, DL**4 and DL**2. The crust structure is made of steel plates by means of bending and welding, which are joined by bolts. The hand buggy panel is the door of cabinet. The bosom of switch cabinet is divided into a breaker chamber, a main bus bar chamber, a cable chamber and a relay chamber by metal partitions. The degree of protection of the entire crust and compartments is IP2X equally. All the metal structures are connected to ground reliably. All the compartments of main circuit system have pressure release channels for independent exhaust.
