The Oil Immersed Transformer series are the kind of the transformer with low noise, low loss and low partial discharge. With rational structure, high-quality material, scientific design, strict craftsmanship and advanced test method, the characteristics of this series products are as follows:
- Excellent dynamic thermal stability, outstanding short-circuit resistance, high lighting impulse resistance, high reliability.
- With excellent overload capacity, it can long-term operate under 110% load.
- Low lose, energy conservation, run economically and maintenance free.
- Contour artistic, compact size, low installation and maintenance costs.
- Performance and parameter conform to or excel the standards of IEC.
- Fully Hermetically oil tank, effectively preventing air from eroding oil and prolonging the service life of the transformer
Ambient conditions for Conventional transformers using:
Oil-immersed power transformers are critical components in electrical power systems, widely used for voltage conversion, energy transmission, and distribution across grids. These transformers employ mineral oil or synthetic ester fluid as both an insulating and cooling medium, enabling efficient operation under high-voltage conditions.
According to the customer's project requirements, we provide customized transformer services.
According to the different insulation materials, Pearl Electric can provide mineral oil distribution transformers without PCB, environmentally friendly FR3 vegetable oil immersed power transformers, and NINAS oil power transformers.
According to the different requirements of iron core materials, Pearl Electric can provide oil-immersed transformers with silicon steel sheet iron cores and oil immersed transformers with amorphous alloy iron cores. Among them, amorphous alloy oil immersed transformers are ultra-high efficiency transformers with losses only 20-30% of silicon steel sheet transformers, which are very suitable for projects with high energy efficiency requirements.
Pearl Electric, an experienced transformer manufacturer since 1958, design and produce various cast resin dry type transformer for different application include rectification transformer, marine/offshore oil platform transformer, rectification traction transformer, Transformer for electrified railway station, Rectification excitation transformer etc.
