50KVA Oil Filled Three Phase Distribution Transformer

Distribution transformers are the end-converter of currents before they reach the households. These machines are responsible for "stepping down" high voltage current to lower usable ratings. There are a variety of cooling design transformers, and one of them is oil-cooling. In which, oil distribution transformers are among the types which use oil for cooling.

The oil-filled distribution transformer is a voltage transformation device that uses an oil cooling technique to minimize transformer temperature. It is placed in a welded steel oil tank filled with insulating oil. When an oil-filled transformer is in operation, the coil's heat and iron core are converted first to insulating oil. Then it is converted to the cooling medium. It may also be split into two types based on capacity: immersed natural cooling transformers and forced air cooling transformers.

50kVA 10kv Oil Filled Three Phase Distribution Transformer Specification and Data Sheet

1. The core is made of cold-rolled silicon steel sheet with high magnetic conductivity and grain orientation, with low no-load loss.
2. The three-phase winding is concentric coil, corrugated oil duct, no paint dipping process and tight band binding are adopted. High mechanical strength, balanced ampere turn distribution, strong short circuit resistance.
3. The positioning structure is added to the body to avoid displacement during transportation. At the same time, all fasteners are equipped with fastening nuts to ensure that the fasteners are not loose during long-term operation.
4. This product is a fully sealed structure. The vacuum oil filling process is adopted when the transformer is packaged, which completely removes the moisture in the transformer, ensures the isolation of the transformer oil from the outside air, prevents the aging of the oil, and improves the operation reliability of the transformer. All transformers of the capacity section are equipped with pressure relief valves, and gas relays with alarm and trip functions can be installed according to user's demand, which ensures the safe operation of transformers.
5. Corrugated oil tank is adopted. This kind of oil tank has the advantages of simple processing, high mechanical strength, good welding effect and no leakage. And because of the strong fluidity of the oil, the heat dissipation capacity of the product is improved.
6. The product is beautiful in appearance, small in volume and small in floor area. It is an ideal maintenance free product.
