It is definitely not a good thing that the voltage regulator is too cheap. Not only is the quality of work poor, but the capacity is far from enough, just like selling fruit on a small beach. Although the price is cheap, half a catty is not bad. . . . But some people just like to be cheap, and then complain when they are cheated! 15KVA regulator, 900 yuan, to be honest, we don't even have enough cost! It's really a cottage in a cottage.
Look at the internal structure of our company.
