There are three following configurations:

(1)DDX1 separate cabinet

(2)DDX1+ fixed or handcart disconnector

(3)DDX1+ Fixed or Handcart Vacuum Circuit Breaker

DGXK2 cabinet type can refer to mature switch cabinets such as GG1A, XGN, KYN28, KYN18, etc. It can also  be non-standard designed according to specific projects and users’ requirements.
