Fire-Resistant Transformer Oil for Factories
Designed for electrical equipment like transformers, transformer oil is usually produced from mineral or synthetic oils and possesses two crucial properties. On one hand, it has excellent insulation, acting as an insulating barrier in electrical equipment to safely isolate components in high-voltage settings and prevent current leakage. On the other hand, its good heat dissipation ability can timely remove heat generated by equipment operation, maintain stable equipment operation, and guarantee the reliable and efficient operation of the power system.
Product Details:Fire-Resistant Transformer Oil for Factories
Throughout its service life, this product has a sulfur level of <0.0005% and an aromatic hydrocarbon level of <3%. No harmful gases escape during its operation, and even if it leaks accidentally, it can be partially degraded in nature without leaving long-term pollution on soil or groundwater. It also has a strong recycling and regeneration capability: after being processed, it can be reused in medium and low-voltage distribution equipment, greatly cutting down the solid waste pressure caused by discarded insulating oil. While preserving superior dielectric loss performance, it constructs a "production-use-recycling" closed-loop green system for users, aiding the power grid in realizing its carbon neutrality targets.
