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。
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 larger angle of rotation, and is also more aesthetically pleasing than before, resulting in a more coordinated overall effect.
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.
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。
The primary cable outlet of the 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.
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 the 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.
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。
After improvement, the rear door structure of the rear outlet scheme has been re optimized on the center pillar compared to before, thereby increasing the space for outlet cables and facilitating user maintenance.
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.
可翻門式頂蓋，安裝方便，省力省時。
The foldable door top cover is easy to install, labor-saving, and time-saving.
使用條件
Usage conditions
周圍空氣溫度不高于+40℃，不低于-5℃，而且24h內其平均溫度不高于+35℃。
The ambient air temperature shall not be higher than+40 ℃, not lower than -5 ℃, and its average temperature within 24 hours shall not be higher than+35 ℃.
周圍空氣相對于濕度在高溫度為+40℃時不超過50%，在較低溫度時有較大的相對濕度，如+20℃時為90%，但考慮到由于溫度的變化有可能會偶然產生適度的凝露。
The relative humidity of the surrounding air does not exceed 50% at the highest temperature of+40 ℃, and there is a significant relative humidity at lower temperatures, such as 90% at+20 ℃. However, considering that moderate condensation may occur occasionally due to temperature changes.
戶內使用時，使用地點的海拔高度不超過2000m。
When used indoors, the altitude of the location of use shall not exceed 2000m.
應安裝在無劇烈震動和沖擊，以及不使電器元件受到腐蝕的場所。
It should be installed in a place without severe vibration and impact, as well as in a place that does not corrode electrical components.
