Easy Move Portable Double Vacuum Transformer Oil Purification Equipment for Sale
Application
Especially for high break-down voltage project which is over 110KV.
In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, transformer oil must be kept absolutely clean and dry. Substation Maintenance Contractors and Utilities need an oil filtration machine that can quickly and reliably process transformer oil to meet or exceed very stringent specification, so TONGRUI company designs and manufactures the most effective, durable, and user-friendly machine running in almost each city of China and serving customers more than 40 countries with good reputation. It can be also used for transformer oil vacuum filling and vacuum drying as well as transformer vacuum evacuation operation. In general, ZJA series are also widely used for industries of power plant, power station, electricity company, transformer factory, metallurgy, petrochemical, mechanical engineering, transportation, railway and transformers manufacturing etc.
Performance of Transformer Oil Purifier
Refining to reduce acid valve and remove particulate impurities.
Dehydrating to remove 100% free water and 99.9% dissolved water,
including insulation dry-out of the winding.
Degassing to remove other dissolved combustible gases such as
Acetylene, Ethylene, Ethane, Methane, Hydrogen and Carbon Monoxide,
and Carbon Dioxide.
