Recently, the 13th China International Power Transformer Market and Technology Development Annual Conference was successfully held in Xuzhou, Jiangsu Province. The conference brought together experts, scholars, enterprise representatives and technical elites from the entire industrial chain of the transformer field. All parties will jointly discuss new directions, new challenges and new requirements for power transformers. In the annual selection event, Shuangjiang Energy was awarded the title of "Recommended Power Transformer Supplier of 2025". 

As a globally leading provider of power insulation oil solutions, Shuangjiang Energy closely follows the national strategic orientation and is committed to creating reliable power insulation oil solutions across the board by enhancing the product's oxidation resistance, dielectric loss stability, and biodegradability. The core competitiveness of the products stems from the synergistic effect of the following technical advantages: 

01Excellent biodegradability 

Deppus natural ester insulating oil contains no harmful substances such as petroleum, halogen or silicone resin. It can be rapidly biodegraded in soil and aquatic environments, with a degradation rate of up to 98% within 28 days. It meets the highest environmental protection standards and is an important green technology for supporting the power grid to achieve the "dual carbon" goals. 

02Strong stability of dielectric loss performance 

The main physical and chemical dielectric performance indicators of Deppus natural ester insulating oil are superior. While ensuring good compatibility, it can significantly reduce the dielectric loss and micro-water content of the oil during the aging process, providing strong support for the long-term healthy and stable operation of transformers. 

03Reliable antioxidant performance 

Through the collaborative innovation of molecular-level refining technology and composite additives, the company has successfully developed power insulating oil with reliable antioxidant performance. Under high-temperature, high-load and continuous electrical stress conditions, this product can effectively inhibit the formation of acidic substances and sludge, significantly slow down the aging rate of insulating media, and provide long-lasting and reliable protection for transformers.
