As an important part of rural power grid distribution, 6KV-11KV Oil Immersed Power Transformer are also a common type. They use transformer oil as insulation and cooling medium, which has the advantages of durability, waterproofing, and low cost. They are mainly composed of iron core, winding, oil tank, oil pillow, insulation sleeve, tap changer, and gas relay.
Using high permeability silicon steel sheets and a cylindrical structure with copper foil wrapped around the shaft, the no-load loss is reduced by 30% compared to traditional models, and the load loss is reduced by 20%.
Adopting high-purity oxygen free copper wire coils, with a local discharge capacity of less than 10PC, the coils have moisture-proof and dust-proof characteristics, and the mechanical strength reaches the industry-leading level.
Choose high-quality insulating oil and use vacuum oil filtration and oil injection processes for better insulation and stronger short-circuit resistance.
