Dry-type Auto Transformer

详情

Overview

Three phase or single phase dry-tyoe low voltage(LV) transformer are used as isolation transformer or to adjust the voltage level in the LV distribution grid.We have advanced technology and imported equipments and made of high quality silicon sheet,copper/aluminum enamel insulated wire(or high quality foil),insulation material and optimal design.Applied with arranged non-bobbin coil winding technology and Vacuum Pressure Impregnation(VPI) process ,The transformer insulation class up to H or C.


Key Features

1. Low losses
2. Low weight and compact dimensions
3. Non-flammable and non-explosive
4. IP21 enclosure(optional)
5. With air cooling based on natural convection(AN) or with forced air cooling(AF)

Application
 

Our low voltage transformers are widely used in industrial applications and in commercial and public buildings. They are also used for adjusting the voltage 
from 690 V to 400 V or as isolation transformers with a voltage ratio of 1:1,
 providing galvanic  separation.

Dedicated products are available for various applications:

- Wind or solar

- Transportation (ie, marine or railways)

- Uninterruptible power supply (UPS)

- Chemical, oil and gas industry

- Motor drive

- Converters

Type
