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

　　2、桥架系统应具有可靠的电气连接并接地(只对金属桥架).

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

　　3、沿桥架全长另敷设接地干线时,每段(包括非直线段)桥架应少有一点与接地干线可靠连接.

　　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、当允许利用桥架系统构成接地干线回路时应符合下列要求.桥架端部之间连接电阻应不大于0.00033欧姆,接地孔应绝缘涂层.在1KV及以下中性点直接接地系统中,受电设备的接地与系统中性线接地相连.装有处动切断供电装轩时,桥架的级长方向金属横截面积应不小于规定值.

　　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、在公共通道或户外跨越道路段,底层梯级的底部宜加垫板。

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

　　6、需屏蔽电器干扰的电缆网路或有防护外部(如:有腐蚀液休,易燃粉尘等环境)影响的要求时,应选用(FB)类槽式复合型防腐屏蔽电缆桥架(带盖)

　　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、强腐蚀性环境应采用(F)类复合环氧树脂防腐阻燃型电缆桥架.托臂、支架也要选用同样材料,提高桥架及附件的使用寿命,电缆桥架.在容易积灰

　　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.
