How is the price of high-voltage switchgear estimated?

Who do I give it to? I study the budget. I have a say. I want to know the price of this thing, which is nothing more than three situations: the first is the material cost, the second is the labor cost, and the third is the auxiliary material cost. As long as you pay attention to these three points, you will definitely not accompany the money. If this thing you are talking about is patented, I suggest you add patent fees, as well as catering and entertainment fees, human fees, travel expenses and horse fees. If you want to make money, you must use your brain well. No matter how much I say, I still need the people who operate it to use it flexibly. What's alive is alive. Finally, I wish you a big fortune.
