Cycle-Resistant Insulating Oil for Energy Storage Transformers
This insulating oil is tailored for scenarios like new energy energy storage converters and oil-immersed transformers, breaking through the performance limitations of traditional products. It enables stable operation across a wide temperature range of -40℃ to 120℃—remaining non-congealable at low temperatures and non-degradable at high temperatures—making it suitable for extreme climates and intensive energy storage cycle conditions. With a low dielectric loss factor combined with anti-gas evolution technology, it reduces gas accumulation in energy storage systems and lowers maintenance frequency.
Product Details：Cycle-Resistant Insulating Oil for Energy Storage Transformers
This insulating oil is crafted for heat-emitting devices like PV energy storage converters and high-power distribution transformers, optimizing heat dissipation and fluid properties. It enables swift internal temperature balancing of equipment through efficient heat transfer, reducing maintenance-related issues triggered by heat buildup. Meanwhile, it circulates unobstructedly even in the narrow oil circuit spaces of equipment, without affecting heat dissipation efficiency. In addition, the product adopts eco-sustainable raw material processes, leaving no hazardous residues behind. Post-application, it can be recycled and repurposed via specialized technology, reconciling equipment operational stability with environmental protection requirements and adapting to the long-term growth of new energy and urban power grids.

1. Oil Change Inspection
Check the moisture content of the oil: Moisture is a common contaminant in transformer oil, and excess moisture can accelerate the aging process.
Measure breakdown voltage: A decrease in breakdown voltage may mean that the quality of the oil has deteriorated and needs to be replaced.
Measurement of Loss Factor: An increase in the Loss Factor may indicate that the oil is aged or contaminated.
2. Factors Affecting Service Life
In order to maintain the service life of transformer oil, regular checks should be conducted on the sealing of the oil filling equipment, the operational performance of the oil storage cabinet, and the breather (hygroscope). Additionally, it is important to ensure that the oil color and quantity are normal prior to filling the transformer with oil. These precautions are crucial for sustaining the stable performance of the transformer oil and extending its lifespan.

Haikun Petrochemical's industrial lubricants are fantastic. They understand customer requirements and provide accurate product information. The salesperson guided me well. - South Asia, Chatterjee Arun
Our transformer oil is grounded in "zero PCB" as its core (threshold) and uses global green standards as its reference. The EU’s Ecolabel demands and the US Green Chemistry Initiative are both fully reflected in the products. It is more than an insulating medium—it holds responsibility for soil, water sources, and the future. Selecting it turns each power operation into a vivid example of environmental consciousness.
