Listing date： 2018-09-16

What is DGXK2? DGXK2=DDX1+ Switch Cabinet with Different Configurations


The main electrical wiring scheme is as follows

DGXK2 Large-capacity High-speed Switching Device

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.

    10kV Short Circuit Current Limiter
    Release time: 2018 - 04 - 28
    DDX1 short-circuit current limiter (abbreviated as current limiter) is an ultra-high-speed switch with strong short-circuit current breaking ability. The short-circuit fault can be completely cut off within 10ms after the short-circuit fault occurs and before peak value of the pre-expected short-current is arrived. It combines blasting cutting technology, current-limiting fuse technology, high voltage insulation technology, electronical measurement and control technology perfectly. It realizes quick current-limiting cutting-off of short-circuit current of power generation, power distribution a...
