6.3 kV Series Distribution Transformers
25 kVA 6.3/0.4 kV Aluminium Winding EcoDesign Transformer
25 kVA 6.3/0.4 kV Aluminium Winding EcoDesign Transformer
We generally manufacture distribution transformers in this power range, mainly in two different types:
- Transformer with conservator tank (WCT),
- Hermetically sealed type (HST),
Below table will help to engineers to select the best option according to environmental conditions which transformer works in:
| High Environmental Temperature | High Altitude | Rural Network | High Humidity | Over Load Conditions | Unstable Loading | |
|---|---|---|---|---|---|---|
| WCT | ⇑ | ⇑ | ⇓ | ⇓ | ⇑ | ⇑ |
| HST | ⇓ | ⇓ | ⇑ | ⇑ | ⇓ | ⇓ |
Meanwhile here is the advantage-disadvantage of the WCT-HST types:
- In HST type, tank pressure is more than WCT type. WCT type generally works under low pressure due to its open to atmosphere,
- In HST type, cooling/insulation oil does not contact to the air (theoretically). Therefore oil maintenance period is longer than WCT type,
- HST type transformers and their related parts generally work under higher temperature (If we evaluate WCT-HST work under same conditions).
