Variable frequency cable structure design
The energy-saving effect of frequency conversion device is very obvious. The frequency conversion speed regulating motor is adopted in the high power motor, and the whole generating set can save 30% of electricity. And after the use of frequency control, the soft start of the motor is realized, so that the motor works smoothly, the motor bearing wear is reduced, and the service life and maintenance cycle of the motor are extended. Therefore, frequency control technology has been widely used in petroleum, metallurgy, power generation, railway, mining and other industries.
