Transformer oil wholesale
Oil for slideways
Description
The main requirements that apply to the chemical and physical properties of transformer oil are:
- viscosity, which should be between 28 to 30 10-6 m2 /s;?
- density – in the range of 0.84 to 0.89 103 kg /m3;?
- oxidation stability, ie the ability to maintain oil compositions during prolonged work their initial settings.
Transformer oils although combustible, but they are not toxic and do not harm the ozone layer. Good oil has a high viscosity, but for power transformers and circuit breakers can make an exception. Using high-quality homogeneous substance without additives – guarantee that equipment performance.
necessary
To increase the service life of transformer oil
- filters used in transformers the expander to absorb substances from oil allocated;
- Do not allow the oil overheating;
- to make continuous cleaning;
- to introduce antioxidants.
