Now there are two ways: 1, you can participate in the national training normally, and all training points register: 1000~ 1500. If you attend intensive classes and other classes, you will have to pay extra! 2, through your power supply unit, report to the State Grid Power Supply Bureau for training, and the certificate will be issued directly by Guodian! The charges are unknown, and the charges in various regions are uncertain! You can go either way. The key is that no matter what your level is, you are a technical installer. You should be familiar with the installation and safe operation specifications. Working with certificates is a matter of face, which is easy for any company, but no company will mess up its reputation and future, so it admits that it has no affiliation! (Guodian stipulates: Any casualty accident within one year 1: light responsibility will be blacklisted by the company 1~3 years! Heavy responsibility cancels its business qualification or light family bans production! ), I suggest you don't take the certificate so seriously and learn the technology well first. I don't think you can get a certificate without the director of the power company! Especially the power lines!
