Our company is a cable tray supply enterprises, grounding on the bridge, you know how much? The grounding problem today we are going to introduce to you is the cable tray, follow the pace of a small series together to see it, I hope to help you.

　　1、桥架系统应具有可靠的电气连接并接地(只对金属桥架)。

　　1, the bridge system should have a reliable electrical connection and grounding (only on the metal bridge).

　　2、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。

　　2, when allowed using the bridge system composed of grounding line circuits should meet the following requirements. The bridge between the end part of the connecting resistance should be less than 0.00033 ohm, grounding hole should remove the insulating coating. In the neutral grounding system of 1KV and below, the grounding of the receiving device is connected with the neutral grounding of the system. A dynamic assembly when the power supply is cut off, the prefect direction of metallic cross-sectional area should not be less than the specified value.

　　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, the other along the bridge length of laying ground lines, each segment (including non straight segment) bridge shall have at least one point and the grounding line connection.

　　4、对于振动场所，在接地部位的连接处应装置弹簧圈。

　　4, for the vibration place, in the grounding part of the connection should be equipped with coil.

　　以上就是小编给大家介绍的电缆桥架的接地问题，我们公司的产品质量值得信赖，我们是您值得信赖的朋友。你们的满意就是我们不懈的追求。让我们共同为明天的美好而努力吧。

　　These are small to the grounding cable bridge introduce problems, the quality of our products is worthy of trust, we are your most trusted friend. Your satisfaction is our unremitting pursuit. Let us work together for a better tomorrow.
