160 kVA 20/0,4 kV – Conservator-Type Distribution Transformers
NE-CTDT160 – 160 kVA 20/0,4 kV – Conservator-Type Distribution Transformers from a supplier working with the best manufacturers in Turkey
These 160 kVA 20/0,4 kV – Conservator-Type Distribution Transformers are open to the atmosphere and equipped with a conservator tank to accommodate oil expansion. When the transformer heats up, the increase in oil volume is absorbed by the conservator. Since they are exposed to the atmosphere, they require regular maintenance, and Oil Dielectric Strength Tests should be performed periodically.
