1、 济南电缆桥架系统软件应具备靠谱的保护接地并接地(只对金属桥架)。

1. Jinan cable bridge system software shall have reliable protective grounding and grounding (only for metal bridge).

2、当容许运用电缆桥架系统软件组成接地主干线控制回路时要合乎以下规定。电缆桥架顶端中间联接电阻器应不超0.00033欧母，接地孔应消除绝缘层镀层。在1KV及下列中性点立即接地系统软件中，受电设备的接地与系统软件中性点接地相接。配有处动断开供电系统装轩时，电缆桥架的级长方位金属材料截面积应不低于标准值。

2. When it is allowed to use the cable tray system software to form the main grounding trunk control circuit, the following requirements shall be met. The middle connecting resistor at the top of the cable bridge shall not exceed 0.00033 ohm female, and the grounding hole shall eliminate the insulation layer coating. In the system software of 1KV and below neutral point immediate grounding, the grounding of the receiving equipment is connected with the system software neutral point grounding. When the power supply system is equipped with a dynamic disconnect, the sectional area of the metal material in the long direction of the cable tray shall not be lower than the standard value.

3、沿电缆桥架总长另敷设接地主干线时，段(包含非平行线段)电缆桥架应至少有一点与接地主干线靠谱联接。

3. When the grounding main line is laid along the total length of the cable bridge, the first section (including non-parallel section) of the cable bridge shall be connected with the grounding main line at least at one point.

4、针对震动场地，在接地位置的相接处应设备弹簧圈。客户如需槽式电缆桥架的别的种类规格型号可来图来函和面洽订购。槽式直达金属表面处理分成静电喷塑、热镀锌、喷涂三种，用静电喷塑时请使用接地板。

4. For the vibration site, the spring coil shall be installed at the junction of the grounding position. If customers need other types, specifications and models of trough-type cable tray, they can order by drawing, letter and face-to-face contact. The trough direct metal surface treatment can be divided into three types: electrostatic spraying, hot galvanizing and spraying. Please use the grounding plate when using electrostatic spraying.

槽式电缆桥架水准敷设时，宜按荷载曲线图选择跨距开展支撑点，跨距一般为1.5～3.0m。竖直敷设时，其固定不动间隔不适合超过2m 针对电缆桥架的界定、型号规格编号、规定、实验方式，针对电缆桥架检测标准、标示、运送和存储等,本规范适用工业生产与工业建筑室外、高压低压输变电工程项目的电缆桥架。

When the trough-type cable tray is laid horizontally, it is advisable to select the span to carry out the support point according to the load curve, and the span is generally 1.5~3.0m. When laying vertically, the fixed fixed interval shall not be more than 2m. For the definition, model, specification number, regulation and test method of cable bridge, and for the detection standard, marking, transportation and storage of cable bridge, this specification is applicable to the cable bridge of outdoor, high-voltage and low-voltage power transmission and transformation projects of industrial production and industrial buildings.

在挑选槽式电缆桥架的荷载级别时，电缆桥架的工作中均布荷载不可超过选定电缆桥架荷载级别的额定值均布荷载，假如槽式电缆桥架的抗震支架的具体跨距并不等于2m时，则工作中均布荷载应符合要求。各种各样部件及抗震支架在考虑相对荷载的标准下，其规格型号规格应与拖盘、梯架的平行线段、弯通系列产品相符合。更多相关内容就来我们网站 //www.comprepyme.com进行咨询吧！

When selecting the load level of trough-type cable tray, the uniformly distributed load in the work of the cable tray shall not exceed the rated value of the selected cable tray load level. If the specific span of the seismic support of the trough-type cable tray is not equal to 2m, the uniformly distributed load in the work shall meet the requirements. Under the standard of considering the relative load, the specifications, models and specifications of various components and seismic supports should be consistent with the parallel section of the towing plate and ladder and the bend-through series products.
