1.上通風門、電纜室門和后門，轉動部分由暗鉸鏈改為明鉸鏈，這使得門轉動平穩，轉動角度更大，同時也比以前要美觀，整體效果更加協調。
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.
2.改進前，一次轉接件與塑料功能件直接相連。假如發生特殊故障，導致一次轉件燒毀，這樣會給現場的維修帶來較大的困難，更換時間較長。而改進后，由于一次轉件改為獨立安裝維修方便，減少了停電時間，經濟效果顯著。
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.MCC柜的一次電纜出線方便更加靈活。相比以前，除了保留原有的側出和后出的方案，更增加了同時側出和后出的混合方案，極大的方便了用戶。
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.
4.8E、16E和24E單元抽屜內的一次電聯的規格可以根據回路的實際電流大小選擇電纜，這有利于用戶現場的維修和更改。
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.改進后，后出線方案的后門結構與以前相比，對中立柱進行了重新優化，從而增加了出線電纜的空間，便于用戶維修。
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.
6.改進后，后出線方案的二次接插件由側面位置改到后隔板位置。這樣，不但減少了二次電纜到端子的距離，而且避免了因現場柜子并柜后無法維修的問題。（600mm寬后出線方案容易產生）。
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.可翻門式頂蓋，安裝方便，省力省時。
7. The foldable door top cover is easy to install, labor-saving, and time-saving.
