High-Dielectric Transformer Oil for Grid Substations
Transformer oil is a specialized oil designed for electrical equipment like transformers. It is usually made of mineral or synthetic oils and has two critical properties. On one hand, it has excellent insulating performance, serving as an insulating barrier in electrical equipment to ensure safe isolation of components in high-voltage environments and prevent current from leaking. On the other hand, its good heat dissipation capacity can timely remove the heat generated by equipment operation, maintain stable operation of the equipment, and ensure the power system operates reliably and efficiently.
Product Details：High-Dielectric Transformer Oil for Grid Substations
During its use, this product has a sulfur content of <0.0005% and an aromatic hydrocarbon content of <3%. No harmful gases are released during operation, and even in case of accidental leakage, it can be partially degraded in the natural environment without causing long-term pollution to soil or groundwater. It also features a high recycling and regeneration rate; after treatment, it can be reused in medium and low-voltage power distribution equipment, significantly reducing the solid waste pressure caused by waste insulating oil. While maintaining excellent dielectric loss performance, it also builds a "production-use-recycling" closed-loop green system for users, helping the power grid achieve its carbon neutrality goals.
