Model and its meaning
The basic cabinet frame is a combined assembly structure, all structural parts are galvanized, and the design is compact and can accommodate more functional units in a small space. It has strong versatility and flexible assembly. The module is 25mm C profile can meet the requirements of various structural types of protection level and use environment.
Using standard module design, it can be composed of standard units such as protection, operation, conversion, control, adjustment, measurement, indication, etc. Users can choose and assemble according to their needs, and more than 200 parts can form different schemes of cabinet structure and drawers. unit.
There are galvanized metal partitions with ventilation holes between the upper and lower drawers. The drawers are surrounded by flame-retardant engineering plastic partitions, so there is a strong insulation and isolation between adjacent circuits.
can be equipped with two sets of main busbars, which can be installed in the main busbar compartment of the switchgear. The two sets of busbars can be installed on the upper and lower parts of the back of the cabinet respectively. According to the wire entry requirements, the upper and lower sets of busbars can be made of different or the same cross-section materials. , The two can be powered separately, can also be used as a backup power source, or the main bus can be discharged in the upper bus compartment of the cabinet.
