LUBTEX TRANSFORMER OIL - 10NL
Product Code: TRX 10NL
Product Description
It is an uninhibited oil that formulated as insulator and cooler for the electrical power transformer. As an insulator, these oils have high dielectric strength compare to mineral oil. It can withstand the electric field in the transformer without breaking down it insulating properties. The dielectric strength at which also known as breakdown voltage of the oil is depends on the presence of the acids, water and other contaminants.
The operation of the electrical power transformer releasing heat to surrounding. These oils are responsible to act as cooler by absorbing the heat and keep the transformer cool from inside. In order to make these oils reliable with the high temperature operation of the electrical power transformer, it has good thermal conductivity and excellent chemical stability. Unlike mineral oil, it is high flammability that may cause fire when operate in high temperature condition.
These oils have fulfils the requirements of:
- IEC 60296 Edition 4.0 uninhibited oil.
- ASTM D1275 method B corrosion test
- IEC 62535 corrosion test
- DIN 51353 corrosion test
Benefits
- Excellent heat transfer capability to ensure heat can be release effectively
- Great oil oxidation and degradation behaviour
- Very good low temperature properties.
- High dielectric strength.
Breakdown Voltage Measurement
Breakdown voltage of the insulating oil can be measured by the dipping 2 electrodes in the oil and the lower breakdown voltage reading means poor dielectric strength also shows that the oil is contaminated. As mineral oil is environment contaminant and easily degrade even with presence of small amount of water thus it has lower dielectric strength.
