Cabinet part: all right-angled parts that operators may come into contact with are all reversed at R angles to prevent scratching and hurting people; the improved busbar frame is more convenient to install busbars and has a more beautiful appearance; the ventilation grid installed on the top cover has anti- Drip function; the top cover is an open structure, which is convenient for users to place horizontal busbars on site;
2. Drawer part: the drawer adopts double-folding positioning groove rivet riveting process, and all parts are molded at one time, so that the drawer is 100% interchangeable. At the same time, the double-folding and rivet technology solves the defects of sheet burr and self-tapping screw tip injury;
3. Connectors: The first-time plug-in for the incoming and outgoing lines of the drawer can be directly used in conjunction with the function board and the metal channel, and the secondary connector is convenient to connect and the wiring is beautiful;
4. Vertical channel: half functional board or iron rectangular channel can be selected, and can be easily interchanged.
