1) the cabinet body structure using aluminized zinc plate is assembled by multiple bending;
2) all operations are performed on the door closed;
3) high protection level, can prevent sundries and pest infestation;
4) simple and efficient "five anti" lockout, prevent the misoperation;
5) replace the breaker handcart interchangeability, good;
6) cabinet installation, reliable wall before the cabinet maintenance, reduce the occupied area;
7) the cable compartment space is abundant, can be connected with a plurality of cable.
