Rectifier dry type transformer for frequency converter is the key technology products. It is the power supply part for the frequency converter. At the same time, it can realize separation and phase shift which make it to be the core part. There are dry type and oil-immersed types in production.
Oil-immersed type rectifier transformer has adopted new insulation configuration and advanced techniques in the electrical design. Short-circuit withstand ability and electric performance have been highly improved. We fully take the influence of harmonics on winding and core into consideration to guarantee the service life of transformer.

We own one workshop for the copper wire processing. Advanced wire extrusion facility will guarantee the wire surface smooth, no burr and better electric performance.

The transformer oil after deep filtering, much lower level of water, air, and impurity makethe products more reliable. All the raw materials have passed through strictly quality testing, the suppliers of which have offered raw materials examined strictly pursuit to ISO9001 standards.
A great many of products with the characteristics of high reliability are used together with the 6 pulse, 12 pulse ,18 pulse and 36 pulse frequency converters or rectifier, according to frequency converter, rectifier type, customers’ requirements and special manufacturing scheme of design.

Structural characteristics

The iron-core is made of low-loss, high-class,cold-rolled silicon steel sheet with new stack configuration featuring 45o fully oblique joint so that the non-load loss is cut down.
Special techniques and configuration are applied to the coil to make the lower load loss and compact size, low-weight, high mechanical strength and strong short-circuit-shock resistance.
We have promoted quite a lot on the basis of traditional configuration and mature   technology as listed following:
Enhance the strength of anti-short circuit impedance and effective supports of coil surface;
Perfect the structure of body orientation to ensure more reliable conditions during long distance transportation and operation;
We can offer many other particular solutions for you.

During recent years, the GDP has been increasing but energy consumption rate is keeping higher which has become the restriction to the economy development. Now government has put into more on energy saving projects, and frequency controller and speed motor is more and more widely used in all possible industries. The device can improve the technology and efficiency; extend the equipment service life as well. The most important is the device can save energy and reduce the consumption which is all accepted by the users.

Since the foundation in 1985, Newonder has been developing and researching experience. In 1996, Newonder successfully produced the power supply for Siemens LV frequency converter, then following the ABB, AB frequency device and finish the production of poly cell parallel power supply. Now Newonder has built cooperation with Robicon, Leader & Harvest, Hicon and other international and Chinese frequency converter manufacturers. The products widely used in power supply, petroleum, metallurgy,  water supply, sewage treatment, textile, paper, medicine, coal, cement industries.
