Compact-Fit Insulating Oil for Urban Box Transformers
This insulating oil is custom-designed for scenarios like new energy energy storage converters and oil-immersed transformers, exceeding the performance restrictions of traditional insulating oils. It runs stably over a wide temperature span from -40℃ to 120℃—remaining unfrozen when cold and undegraded when hot—thus adapting to extreme weather and frequent energy storage cycle operations. Its low dielectric loss factor, together with anti-gas evolution technology, minimizes gas buildup in energy storage systems and cuts down maintenance frequency.
Product Details：Compact-Fit Insulating Oil for Urban Box Transformers
Designed for heat-generating equipment like photovoltaic energy storage converters and high-power distribution transformers, this insulating oil optimizes heat dissipation and fluidity. It can quickly balance the internal temperature of equipment through efficient heat conduction, reducing maintenance issues caused by heat accumulation. Meanwhile, it circulates smoothly even in the compact oil circuit space of equipment, without hindering heat dissipation efficiency. In addition, the product uses eco-friendly raw materials and processes, leaving no harmful residues. After use, it can be recycled and reused via professional technology, balancing the stability of equipment operation and ecological protection needs, and adapting to the long-term development of new energy and urban power grids.

1. Applicable Industry
Power Supply Systems: Transformer oils are used in power distribution systems for large building projects, ensuring the electrical safety of the entire structure.
High-Frequency Equipment: In high-frequency and high-power electronics, transformer oils provide insulation and cooling, ensuring stable operation and lowering the risk of thermal failures.
Laboratory Research: In electrical engineering R&D, transformer oils are applied to assess insulation and thermal management, contributing to the development of new electrical technologies and materials.
2. Factors Affecting Service Life
In order to ensure the service life of the transformer oil, the sealing of the oil filling equipment, the working performance of the oil storage cabinet and breather (hygroscope) as well as whether the oil color and oil quantity are normal should be checked frequently before filling the transformer with oil. These measures help to maintain the stable performance of transformer oil, thus extending its service life.

"From the beginning of raw material selection, we embarked on a green journey. Using natural vegetable oil as the basic raw material, such as non genetically modified rapeseed, these raw materials are sourced from green and sustainable sources. The plant-based formula endows the product with excellent biodegradability, allowing it to completely decompose in the natural environment in just three months without leaving any burden on the earth, in stark contrast to traditional mineral oils that take years or even decades to degrade. According to third-party authoritative testing, in multiple simulated leak tests, the soil microbial activity in the area where our product was used returned to normal within 3 weeks, and the surrounding vegetation became lush and vibrant again after 1 month.
