Eco-Friendly Insulating Oil for Wind Turbines
For electrical equipment such as transformers, transformer oil is a specially formulated oil typically derived from mineral or synthetic oils, with two vital attributes. One is its outstanding insulating properties, which enable it to act as an insulating barrier in electrical equipment, safely separating components in high-voltage conditions and avoiding current leakage. The other is its strong heat dissipation ability, which can promptly dissipate heat generated by equipment operation, maintain stable equipment performance, and ensure the reliable and efficient operation of the power system.
Product Details：Eco-Friendly Insulating Oil for Wind Turbines
When in use, this product boasts a sulfur content below 0.0005% and an aromatic hydrocarbon content under 3%. No hazardous gases are emitted during its operation, and if there is an accidental leakage, it can be partially broken down naturally—this prevents long-term contamination of soil and groundwater. Additionally, it has a high recycling and regeneration rate: after proper processing, it can be reapplied to medium and low-voltage distribution devices, greatly easing the solid waste burden from discarded insulating oil. It not only retains outstanding dielectric loss performance but also establishes a closed-loop green system of "production-use-recycling" for users, supporting the power grid in reaching carbon neutrality.

In our production workflow, continuous innovation drives us to bring in advanced clean production techniques, all to minimize energy consumption and greenhouse gas emissions. For every ton of product manufactured, when compared to conventional mineral oil extraction processes, we achieve a carbon emission reduction of up to 800kg, helping to alleviate global warming. Additionally, we’ve developed a comprehensive "Old Oil Recovery Program," through which we’ve successfully collected 200 tons of waste oil. This oil undergoes scientific processing to be transformed into biofuels, enabling resource recycling. Currently, the recycling rate is an impressive 92%, and we’re making steady progress toward the 2026 goal of 100% recycling.
