Start from the lotus rhizome transformer

A component of a self-coupling transformer installed in a self-starting cabinet, suitable for general industrial AC 50HZ with a voltage of 380V and a power of 800kW or less. Phase squirrel cage induction motor is used for step-down starting. Self-coupling transformer is a kind of single-loop transformer, which is wound by a winding on the primary and secondary sides. It's fixed. Compared with ordinary transformers with the same capacity, self-coupling transformers are especially useful when the ratio is close to Yu 1, so in the voltage phase. Recent high-power transmission transformers are widely used, and more than 10 kilowatts of asynchronous motors are widely used in step-down starter boxes.

R transformer

R type transformer is 30% less than the EI transformer, 40% thinner and 40% lighter. R type transformer magnetic flux leakage is minimal, 10 times smaller than the EI type transformer. The heat generated by the R type iron core transformer at least 50% smaller than the EI type transformer. R type transformer does not produce noise, this feature much better than the EI type transformer or have clearance cut form of iron core Core transformer. Compared with the ring transformer, R type transformer has better performance, higher reliability, insulation performance is strong, Easy to install. R the structure than the EI type transformer and C type transformer is simple but the reliability and quality are higher than they. R type transformer allow you to have fine design to improve business efficiency and reduce cost. R type transformer design basically meet all global safety standards. R type transformer we have production for many years, and yield increase every year. Using R type transformer company now
