一、母線槽的安裝可直接從變壓器接到低壓配電柜，也可從低壓柜直接接到配電系統作為配電干線線路。 帶插口的母線槽，可通過插接頭箱或插接開關箱，能很方便地引出電源分路。母線槽具有體積小、結構緊湊、傳輸電流大、維護方便等優點。

　　First, the installation of the bus slot can be directly received from the transformer to low-voltage distribution cabinet, or from the low-voltage cabinet directly connected to the distribution system as the main line of distribution. The bus duct with a socket can conveniently draw out the power supply through the socket head box or the plug-in switch box. The utility model has the advantages of small volume, compact structure, large transmission current, convenient maintenance, etc..

　　1、空氣清潔，相對濕度在高為+40℃時不超過50%，在較低溫度時允許有較高的相對濕度;例如+20℃時為90%，但應考慮到由于溫度的變化，有可能會偶然地產生適度的凝露。

　　1, clean air, relative humidity was the highest in +40 degrees is less than 50%, allowing a higher relative humidity in the low temperature of 90% DEG C; for example +20, but should be taken into account due to temperature changes, may occasionally produce moderate.

　　2、母線槽保證在下列環境中長期正常工作:

　　2. The busbar ensures long term operation in the following environment:

　　3、周圍空氣溫度在-5～+40℃之間，并在24h內其平均溫度不高于+35℃;

　　3, the ambient air temperature is between 5 and +40 degrees centigrade, and the average temperature in 24h is not higher than +35 degrees centigrade;

　　2、.海拔高度不超過2000m;

　　2. Altitude is not more than 2000m;

　　二、槽式電纜橋架接地要點

　　Two, the grounding of groove type cable bridge

　　1、對于振動場所，在接地部位的連接處應裝置彈簧圈。

　　1. For vibration site, the spring shall be installed at the joint of the grounding part.

　　2、橋架系統應具有可靠的電氣連接并接地(只對金屬橋架)。

　　2 the bridge system shall have reliable electrical connections and earthing (only for metal bridge).
