Product Description

Product overview:

The autotransformer is made according to the self inductance phenomenon in electromagnetic induction,it
mainly regulates the voltage level.A self-transformer is a transformer that is the primary and secondary
windings of the same winding.Accroding to the structure can be divided into pressure adjustable and fixed.
Generally used for mechanical and electrical speed occasions,which is characterized by the difference between
the one or two voltage is not large,is now widely used frequency control.
The core of the product is cold rolled oriented high quality silicon steel sheet,and the coil structure adopts a
cylinder,an elliptical cylinder and a rectangular cylinder.Small size,excellent performance,safety and reliability.

Application area:

Widely used in industrial and mining enterprises and the use of import and export equipment,etc.

Product features:

Since the calculation capacity of the self coupling transformer is less than the rated capacity,the main dimension
of the self coupling transformer are smaller in the same rated capacity,therebe reducing the cost.
The reduction of the effective material causes the copper loss and the iron loss to be correspondingly reduced,
so the efficiency of the self coupling transformer is high.
Since the short circuit impedance of the self coupling transformer is smaller than that of the double winding
transformer,the voltage change rate is small,but the short circuit current is larger.
