S-M-30-2000kVA Three Phase Oil-immersed Transformer for oversea
Different from normal type, S - M -30 -2000KVA Three phase oil-immersed transformer is cooled by the corrugated plate of tank without conservator. It is applicable to 11kV, 50Hz power transmission and distribution system for power supply and lighting in industrial and agricultural field for oversea project.
Feature:
1.Long-term reliable service life:
Fully enclosed transformer tank and rim shall be bolted together or welded firmly. Isolation between oil and air keeps insulation away from moisture, which lowers insulation aging and improves service life.
3.Free from untanking:
Free from untanking before operation, so its cost is saved.
4.Free from maintenance.
5.Low noise:
Impacted structure in design, new material and new technology adopted and low noise.
6. Small size and artistic appearance:
Owing to the corrugated plate used for radiation, oil volume is changed by adjustment and compensation through expansion and shrinkage of corrugated plate when the temperature of oil is changed. Corrugated tank is small size in good looking.
