Product introduction
* This model is produced in accordance with Chinese national GB standards and the international IEC standards.
* It uses oil as the main insulation means of the transformer, and relies on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation, etc.
* The main components: iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure release valve), radiator, insulating casing, tap switch, gas relay, thermometer, oil purifier, etc.
* Widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms and oil production platforms; especially suitable for use in flammable, explosive and other harsh environments.
Main Functions And Features
1. The low-voltage winding is of cylindrical or spiral structure, with high mechanical strength and good short-circuit resistance.
2. The corrugated oil tank is adopted to replace the oil conservator. The oil tank cover and the oil tank are all welded along the edge or fastened with bolts, thus prolonging the service life of the transformer oil.
3. After oil removal, embroidery removal and phosphating treatment, the product is sprayed with three times of primer and one time of finish paint inside and outside. The product is salt fog proof, damp heat proof and fungus proof, which can meet the special requirements of metallurgy, petrochemical system and wet and polluted areas. It is beautiful and reliable.
4. The transformer oil tank is fully sealed, and equipped with pressure reducing valve, signal thermometer, gas relay, etc according to the standard requirements to ensure the safe operation of the transformer.Product parameter table
