Product description
The 3150KVA oil-immersed transformer is a transformer that is completely isolated from the outside atmosphere inside the oil tank, and the technical performance parameters of the product have reached the international level. The change of transformer volume is compensated by the expansion and contraction elasticity of the corrugated oil tank wall, and the external moisture and oxygen can not enter the oil tank, which not only does not reduce the dielectric strength, but also avoids the aging of the insulating material, and the product does not need to be checked before the operation of the core, which greatly improves the reliability of the transformer operation.
Standards:
GB 1094.1-1996 GB1094.2-1996
GB 1094.3-1996 GB1094.5-2003

GB/T 10237-1998 B/T 3837-1998
Main functions and features of 3150KVA oil-immersed transformer:
There are no oil conservators, dehydrating breathers and other protective devices to ensure that the transformer oil is not in contact with the air, and that the transformer oil does not need any treatment and can be used continuously for more than 10 years;
The seals are made of rubber with excellent performance;
Vacuum oil injection process is adopted
It is widely used in urban power grids, petrochemical, metallurgy, light textiles, enterprises and mines with high humidity and inconvenient maintenance.
