power machine-building industry

The piezoelectric transducer is widely used in ultrasonic cleaning machine and high-power industry cleaning devices.

它广泛应用于超声波清洗机及工业用大功率清洗设备。

These years, the big machine set, high capacity and high voltage tendency become the development standard of power industry. This means higher demands to power system.

目前的情形是，我国的电力系统发展趋势正向着大机组、大容量、高电压的标准迈进，这就对电力系统的可靠性提出了更高更严格的要求。
