One, product introduction
QZB series autotransformer for AC 50HZ, rated voltage 308V. Power 11 ~ 315(KW) three-phase squirrel cage induction motor is not frequent starting, to improve the motor startup of the transmission network.
Two, product features
The F H class insulation system, based on the entire service life, self coupling transformer to maintain electrical and mechanical properties, excellent F, Hmaterial is not easy to aging, resistant to shrinkage and anti compression, add a very strong elasticity, which can ensure transformer used for several years Hou Renbao hold tight structure, and can short circuit withstand pressure, self coupling transformer by H soaking paint in the vacuum pressure impregnation(VPI), and then the oven curing at high temperature.
