Are chemical enterprises that produce PVC PP PS PET and other plastic sheets harmful to human health? Do you need to be proficient in frequency converters and temperature control instruments to be an electrician there? hello, how do you say harm? It's impossible without certainty. If you are an electrician, you can't stay in the workshop for a long time. You should have your lounge. Only when the equipment is broken, you need to check and repair it. So the harm is not great ~ ~ ~ ~

Because you are an electrician, you need to be familiar with the equipment you maintain, analyze the circuit wiring of the equipment, and find out where the problems may occur. For temperature control instruments and frequency converters, I feel that under normal circumstances, you don't need to know their principles from the side, as long as you have a certain grasp of their parameters and operation methods. Generally, this kind of equipment has after-sales service, so you just need to call. They will also help you solve the problem, and you can't be the only electrician in the factory. Other people will help you, so you don't need to worry ~ ~ I hope you can understand ~ ~ I wish you a smooth work ~ ~
