Fluctuation-Resistant Transformer Oil for Urban Grids
Specifically developed for new energy energy storage converters, oil-immersed transformers, and similar use cases, this insulating oil overcomes the performance limitations of traditional options. It maintains stable operation between -40℃ and 120℃—not congealing in low temperatures and not deteriorating in high temperatures—making it compatible with extreme climatic settings and intensive energy storage cycling. A low dielectric loss factor combined with anti-gas evolution technology decreases gas accumulation in energy storage systems and reduces maintenance needs.
Product Details：Fluctuation-Resistant Transformer Oil for Urban Grids
Tailored to heat-emitting devices such as PV energy storage converters and high-power distribution network transformers, this insulating oil enhances heat-dissipating and flow performance. Through highly effective thermal transfer, it rapidly equalizes the internal temperature of equipment, lowering the risk of maintenance problems triggered by heat buildup. It also circulates unobstructedly in the narrow oil circuit spaces of equipment, ensuring heat dissipation efficiency remains unaffected. Furthermore, the product adopts environmentally friendly raw material technologies, with no toxic components left behind. Post-use, it can be regenerated for reuse using professional techniques, reconciling equipment operational stability with eco-protection requirements and suiting the long-term growth of new energy and urban power grids.

1. Applicable Industry
Power Supply Systems: In extensive building developments, transformer oils are crucial in power distribution systems to ensure the electrical safety of the facility.
High-Frequency Equipment: Transformer oils are used in high-frequency and high-power electronic systems for insulation and cooling, which helps maintain stable performance and reduces thermal failure risks.
Laboratory Research: In the realm of electrical engineering research and development, transformer oils are utilized to test insulation and thermal management of devices, facilitating the advancement of new electrical equipment and materials.
2. Factors Affecting Service Life
To ensure transformer oil remains effective over time, regular inspections of the sealing on the oil filling equipment, the functionality of the oil storage cabinet, and the breather (hygroscope) are necessary. Additionally, confirming that the oil color and quantity are normal prior to filling the transformer is crucial. These actions help maintain the stable performance of the transformer oil, ultimately extending its service life.

I'm super impressed with Haikun's industrial lubricants. They work like a charm, reducing friction significantly. The packaging is sturdy, ensuring no leakage. The price is a steal for the quality. Their team is very professional. - South America, Maria Rodriguez
Each barrel of transformer oil you go for supports the "green grid." Every 1,000 liters of our product in use means 3 fewer trees are cut down; traditional mineral oil production, by contrast, uses more fossil energy. This year, we’ll take 1% of profit from each order and donate it to the Global Grid Greening Alliance. It finances substation environmental upgrades in developing countries, with 8 projects in Kenya and Thailand already funded.
