What are the categories for specialty transformers ?

I am an engineer in the field of specialty transformers and my work is working on various different projects. In recent days my friends invited me to make a project for the categories for specialty transformers. Today I come to this forum to turn to you to discuss my understandings are appropriate.

The project for the categories for specialty transformers begins now:

*Special transformer *refers to the material, the role, use, etc. are different from the conventional transformer transformer. According to material points are: amorphous dry-type transformers, epoxy resin casting transformers; According to the role of points are: Scott transformers, three-phase single-phase transformers, phase-shifting transformers; By use points are: UV mechanical transformers, spark transformers, dyeing and finishing machinery transformers, rectifier transformers, energy-saving equipment, such as transformers.

(1) energy-saving transformers:

This series of energy-saving transformer for AC 50HZ, working voltage 500V or less. The series of transformer insulation heat rating for the F-class.This series of energy-saving transformer core for the cold-rolled high-quality silicon steel sheet laminated, the coil structure using cylindrical, oval and rectangular cylinder. Small size, excellent performance, safe and reliable.

(2) ZSG series rectifier transformer:

Widely used in industrial charging, DC lighting, DC excitation, electrolytic plating, power drag, ZSG series rectifier transformer with small size, light weight, simple maintenance, reliable operation and so on.

(3) EPS, UPS special transformer:

EPS, UPS special transformer with high permeability and low loss, low noise, low temperature, anti-radiation and non-toxic, maintenance-free, high environmental protection and so on. The special transformer built high impedance, space efficiency and energy conversion efficiency.

(4) QZB series step-down start with autotransformer:

The use of autotransformer to reduce the power supply voltage to reduce the starting current, but also by selecting the different taps of the autotransformer to change the starting current and to achieve the purpose of changing the starting torque, the starting mode in the starting voltage on the power supply Small, the impact of the smaller mechanical start, the motor start time is shorter, usually used for 320KW following three-phase squirrel cage asynchronous motor for infrequent start, stop using.

(5) BK series control transformer

As a variety of industry machine tools and mechanical equipment control, lighting, light power used.

Ps: Excuse me if I was wrong in words or expressions as I am a green hand in the field of specialty transformers. I need continual learnings.

What is your idea ? Do you agree with my ideas ? Any of your ideas would be highly appreciated.

May someone would like to help ?

thanks in advance
