HIVOLT products of PTT Lubricants are high-quality transformer oils. Naphthenic and paraffinic hydrocarbons (cycloparaffinic acid & paraffin type) are suitable for transformers. General power transformers can be used as electrical insulators. In the capacitive switch, the Wi-Fi circuit is connected.

HIVOLT 99 PLUS is a transformer oil for power transformers (power transformers) with mixed reactant resistance. Oxidation, also known as naphthenic acid, is produced from special quality naphthenic acid base oils. High dielectric strength (insulation strength) meets IEC requirements 60296: 2020, Type A and IEC 61125: 1992, Method C (Organic Stability) with Naphthine Nick helps to dissipate the heat generated inside the transformer. Well, it also has a help function. Keep the gas generated inside the transformer in the oil well, reduce the pressure accumulated inside the transformer, and do not react with the copper wire coating and components inside the transformer, with a long service life, and it is resistant to reactions with the following substances

HIVOLT 99 is mostly a transformer oil used in power transformers (power transformers) and contains active compounds. The oxidation method, also known as the oxidation method, is made with the same special quality naphthenic acid base oil (naphthenic acid) as raw materials. High dielectric strength (insulation strength) meets ASTM requirements. D3487-16 contains Naphtha Nickel so it also helps to cool the heat generated inside the transformer and has the characteristics of helping to retain the gas generated inside. The transformer is well preserved in oil. It does not react with the copper wire coating, and the internal components of the transformer have a long service life and good oxidation resistance.

HIVOLT PLUS is a transformer oil used for general-purpose transformers. Antioxidant additives, also known as antioxidant additives, are made from reaction-resistant special-grade paraffin base oil (paraffin). Aerobic is very good, and it is difficult to deteriorate with age. Long-term use is electrically insulated. (Insulation strength) Highly meets IEC requirements 60296:2020, Type B and IEC 61125:1992, Method C (Marx's stability) includes non-reactive copper wire coating and gold wire coating parts and nakka ama parts
