Can Transformer Oil Be Replaced With HL Hydraulic Oil?
Can transformer oil be replaced with HL hydraulic oil?
No, even if the viscosity, flash point or pour point is similar, the refining degree is different, and no tests of electrical properties has done for the HL hydraulic oil, there may be safety concerns and electrical accidents.
Can different types of hydraulic oils be replaced with each other?
No, hydraulic oils have HL, HM, HV, HS four types, each with its own special application purposes and indicators. First of all, each type is designed for different hydraulic systems with specific indicators. The compatibility to sealing materials is the most difference. The types of hydraulic pumps, filtering systems, drying systems are different, and requires suitable hydraulic oil to meet the equipment requirement. Only the hydraulic system with ester-type anti-flame oils has some similarities with those using mineral hydraulic oils.
