1. For the 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)

　　3、沿橋架全長另敷設接地干線時,每段(包括非直線段)橋架應少有一點與接地干線可靠連接.

　　3, along the length of the bridge to lay the ground line, each paragraph (including non linear section) bridge should be at least a little reliable connection with the grounding trunk

　　4、當允許利用橋架系統構成接地干線回路時應符合下列要求.橋架端部之間連接電阻應不大于0.00033歐姆,接地孔應絕緣涂層.在1KV及以下中性點直接接地系統中,受電設備的接地與系統中性線接地相連.裝有處動切斷供電裝軒時,橋架的級長方向金屬橫截面積應不小于規定值.

　　4, when allowed using the bridge system composed of grounding line circuits should meet the following requirements. The bridge between end connection resistance should be less than 0.00033 ohm, grounding hole should remove the insulation coating at 1KV and below the neutral grounded system, electrical equipment grounding system with neutral grounding connected. A dynamic assembly when the power supply is cut off, the prefect direction of metal cross section bridge should be not less than the specified value.

　　5、在公共通道或戶外跨越道路段,底層梯級的底部宜加墊板。

　　5, in public or outdoor crossing the road section, the bottom of the bottom of the ladder should be added padding.

　　6、需屏蔽電器干擾的電纜網路或有防護外部(如:有腐蝕液休,易燃粉塵等環境)影響的要求時,應選用(FB)類槽式復合型防腐屏蔽電纜橋架(帶蓋)

　　6, the need to shield electrical interference cable network, or to protect external (such as: corrosion liquid, flammable dust and other circumstances) influence, should choose (FB) trough type composite anti-corrosion shield cable bridge (with cover)

　　7、強腐蝕性環境應采用(F)類復合環氧樹脂防腐阻燃型電纜橋架.托臂、支架也要選用同樣材料,提高橋架及附件的使用壽命,電纜橋架.在容易積灰

　　7, strong corrosive environment should be used (F) composite anti-corrosion epoxy resin flame retardant type cable tray bracket, bracket. To use the same material, improve the service life of the bridge and annex, cable tray in the dirt.
