TRANSFORMER INSULATING FLUIDS
Naphthenic Mineral Transformer oils
Ergon’s HyVolt naphthenic oils are premium dielectric fluids meeting the latest requirements of IEC 60296:2020 type A and B.
Ergon’s naphthenic transformer oils HyVolt I and HyVolt III products made from virgin crude oil demonstrate superior oxidation stability and electrical properties, while exhibiting non-corrosive behavior toward copper and silver and delivering excellent cooling for longer asset life.
Together with their low temperature performance, this exceptional set of properties make HyVolt suitable to all climates and the fluids of choice to meet the most demanding requirements from leading transformer manufacturers, utilities and industrial users.
HyVolt products contain NO undeclared additives such as DBDS, PCB, metal passivator/deactivator or silicone.
Ergon Refining holds both ISO 9001 quality and ISO 14001 environmental management standards accreditations.
This Type B uninhibited electrical insulating oil is produced from severely hydrotreated naphthenic oil meeting the general specifications of Table 4 as defined in IEC 60296, ed. 5, 2020 and classified as TVBU.
HyVolt I also meet the latest Australian standard AS60296:2017 table 2 General Specifications for uninhibited oil.
This Type A inhibited electrical insulating oil is produced from severely hydrotreated naphthenic oil meeting the general specifications of Table 3 as defined in IEC 60296, ed. 5, 2020 and classified as TVAI.
HyVolt III also meet the latest Australian standard AS60296:2017 table 2 General Specifications as well as the more stringent requirements for special applications.
Synthetic and Natural ester fluids
Please contact us to find out more about our new range, why, how and where to use ester fluids.
Biodegradability: our ester fluids are readily biodegradable as measured by the OECD 301B method
K-Class fluid: with a fire point above 300°C, our ester fluids offer a safer higher fire rating for specific applications or conditions, and comply with FM Global requirements.
Produced in Belgium by Nyco, one of the world experts in synthetic esters, this fluid meets the latest IEC 61099 for synthetic esters.
It is second to none and is also approved for MR tap changers in MR alternative fluids brochure (p10).
It has the lowest viscosity of all approved K-class synthetic esters hence delivering better cooling performance.
Nyco synthetic esters have been in use as insulating oil for decades and are approved by most global transformer manufacturers.
Additional information and key terminology:
- TVBU = Transformer / Virgin oil / B type / Uninhibited, eg HyVolt I
- TVAI = Transformer / Virgin oil / A type / Inhibited, eg HyVolt III
Used oil recycling: naphthenic mineral transformer oils last for decades and are fully recyclable. If you have used transformer oil to dispose of, please contact us for support.
