L-TGA Series
Features ultra-long oxidation stability and excellent water separation, effectively extending service life and reducing downtime, along with good air release and anti-corrosion properties to ensure efficient and stable system operation.
Product Performance: Excellent oxidation stability with D943 oxidation time exceeding 10,000 hours, effectively extending oil service life, reducing downtime, lowering operation and maintenance costs, and improving efficiency. Good demulsibility, with deeply refined hydrotreated base oil providing excellent water separation. Good air release and very low foaming properties ensure sensitive and accurate speed control system operation. Good corrosion resistance, containing rust inhibitors and metal deactivators to protect metals such as iron and copper from corrosion. Application: KTL series long-life turbine oil is a premium turbine oil suitable for lubrication of bearings and control systems in steam turbines, and also for high-speed gear drives in transmission systems.
