In the engineering design process of aluminum alloy Cable tray supplier system, the grounding wire should cooperate closely with the building structure

In the engineering design process of aluminum alloy Cable tray supplier system, the grounding wire should cooperate closely with the building structure, technology and related industries to determine a better configuration, and the design content must meet the following requirements:
1.The system design must ensure that the bridge can meet the total number of cables to be laid in the project. And leave some leeway.
2.The charging level must be selected correctly. When estimating the cable weight, it is recommended to consider the tolerance weight. Temporary additional concentrated loads for construction and maintenance or other special loads that must be considered. Like wind load and snow load, they should be calculated according to the appropriate combination.
3.The design of the system shall indicate the direction of the aluminum alloy bridge, the specification and number of layers of the pallet or ladder, the position of various curves, widening, lifting and telescopic adjustment points, as well as support and suspension frame configuration and related dimensions.
4.The outline of the system should indicate the interlayer spacing of aluminum alloy bridge, the interlayer elevation of bracket and hanger, the elevation change of path direction and the installation method of bracket and hanger, etc.
5.A detailed list of the specifications and quantities of pallets, ladders, elbows, brackets and hangers and major accessories required for the aluminum alloy bridge system shall be prepared, and technical requirements such as load levels and loads shall be indicated. How to select the working ground wire of aluminum alloy cable tray is the principle of sharing your selection provided by Zoomlion: the principle of selecting the working ground wire of aluminum alloy bridge is to ensure that the test phase forms a closed loop, so that the instrument can obtain the correct test waveform. It should also be noted that the work ground wire must be connected to the system ground wire so that the human, instrument ground wire, high voltage equipment ground wire and low wire and cable jumper ground wire test are in the same position to ensure personal safety and equipment integrity. If there is an interphase fault in the cable, the working ground wire must be one of the phase wires, and the phase wire used as the ground wire must be connected to the system ground. For aluminum alloy bridges with lead-free bushings, during the high voltage breakdown test, most of the faults are discharge to the ground or space.
Theoretically, the aluminum alloy Cable tray supplier fault also forms a closed loop relative to the ground or space, but in practice, the equivalent impedance in the loop is very large, so it is impossible to obtain the correct test waveform on the instrument.
In the test, if you find this situation, you can use the method of directly repairing the suspected failure point to solve the problem, no matter which kind of grounding wire is used, your grounding location must be reliable.
