1. The upper ventilation door, cable room door, and rear door have been changed from concealed hinges to exposed hinges in their rotating parts, which makes the door rotate smoothly, with a greater angle of rotation, and is also more aesthetically pleasing than before, resulting in a more coordinated overall effect.
Before the improvement, the primary adapter was directly connected to the plastic functional component. If a special malfunction occurs, resulting in the burning of a rotating part, it will bring greater difficulties to on-site maintenance and a longer replacement time. After the improvement, due to the convenience of independent installation and maintenance instead of one-time parts transfer, the power outage time was reduced, and the economic effect was significant.
3. The primary cable outlet of the MCC cabinet is more convenient and flexible. Compared to before, in addition to retaining the original side out and rear out schemes, a hybrid scheme of simultaneous side out and rear out has been added, greatly facilitating users.
The specifications of the primary electrical connection in the drawers of 4.8E, 16E, and 24E units can be selected based on the actual current size of the circuit, which is beneficial for on-site maintenance and modification by users.
5. After improvement, the rear door structure of the rear outlet scheme has been re optimized compared to before, increasing the space for outlet cables and facilitating user maintenance.
After improvement, the secondary connector of the rear outlet scheme has been changed from the side position to the rear partition position. This not only reduces the distance from the secondary cable to the terminal, but also avoids the problem of being unable to repair after on-site cabinet merging. The 600mm wide rear outlet scheme is easy to generate.
7. The foldable door top cover is easy to install, labor-saving, and time-saving.
