The transformer accessories mainly include Buchholz relay, tap changer, oil level gauge, butterfly valve, moisture absorber, pressure reducing valve, cross flow cooling fan, bimetal thermometer, epoxy resin insulator, etc. New and old customers are welcome to purchase and customize.

Introduction:

Three phase dry type isolation transformer is a new generation of energy-saving power transformer developed by our factory from 300VA to 1600KVA on the basis of international similar products and in accordance with international and national standards such as IEC439 and GB5226. The winding adopts hole array winding. Vacuum impregnation is adopted for the transformer to make the insulation level of the transformer reach F or H, and the product performance reaches the advanced level at home and abroad. SG series three-phase dry type isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltage lower than 2000V. All these can be customized according to the different requirements of the end user.
Normal service conditions:
1. The altitude shall not exceed 2500M
2. Ambient medium temperature: ≥ - 25 ℃, ≤+40 ℃
3. Current and voltage waveforms are similar to sine waves.
4. No rain and snow erosion, no obvious shaking and impact vibration at the installation site.

5. No explosion hazard, gas and conductive dust.
