(2) overhead and underground metal pipes, should be in and out of buildings and lightning protection grounding device connected at.
Fixed on the building of holiday lights, aviation obstruction lights and other electrical equipment of the line, should be based on the importance of building the mine to take corresponding measures invasive radio waves:
a. no metal or electrical equipment protection network should cover the protection of air terminals within;
b. The line leads from the distribution box should wear steel. Ends of the pipe is connected with metal distribution box; the other side of the metal casing and electrical equipment, protective cover is connected, and lightning protection devices connected to your nearest roof. Pipe should be located off the middle of the jumper.Third and experience
This internship, I learned that the size of the plant level, the production process and the production of some conventional products, the study design in the future I believe there will be more help.
In addition, I feel that through this internship for me after the choice of electrical equipment, lighting, power, systems, lightning protection and grounding aspects of the design will be very helpful thank the school and the teacher gave us this Gui internship opportunities.
