Low-Loss Transformer Oil for Energy Storage Converters
Designed specifically for new energy energy storage converters, oil-immersed transformers, and similar applications, this insulating oil overcomes the performance constraints of conventional products. It boasts the ability to operate stably within a broad temperature spectrum from -40℃ to 120℃: it does not freeze in low temperatures and does not deteriorate in high temperatures, adapting well to extreme weather and frequent energy storage cycling. Its low dielectric loss factor, paired with anti-gas evolution technology, minimizes gas buildup in energy storage systems and reduces the need for maintenance.
Product Details：Low-Loss Transformer Oil for Energy Storage Converters
Developed for heat-generating equipment including photovoltaic energy storage converters and high-power distribution network transformers, this insulating oil improves its heat dissipation and flow characteristics. It can quickly balance the internal temperature of equipment via effective thermal conduction, minimizing maintenance issues resulting from heat accumulation. Moreover, it circulates smoothly within the compact oil path areas of equipment, not impeding heat dissipation effectiveness. Additionally, the product uses green raw materials and technologies, with no toxic components remaining. After use, it can be reprocessed and reused using professional techniques, balancing the stability of equipment operation and environmental needs, and fitting the long-term development of new energy and urban power grids.

1. Oil Change Inspection
Moisture Content Check: Assess the moisture level in the oil, as excess moisture is a frequent contaminant in transformer oil and can significantly accelerate aging.
Breakdown Voltage Measurement: Measuring the breakdown voltage is crucial; a decline in this value may indicate that the oil quality has worsened and replacement is necessary.
Loss Factor Measurement: An increase in the Loss Factor may suggest that the oil has aged or become contaminated.
2. Factors Affecting Service Life
To guarantee the longevity of transformer oil, it is essential to frequently inspect the sealing of the oil filling equipment, the functionality of the oil storage cabinet, and the breather (hygroscope), as well as to verify that the oil color and quantity are within normal ranges before filling the transformer. These checks are vital for maintaining the stable performance of the transformer oil, ultimately prolonging its service life.
