Tubular oil indicators are established on dilators of the transformer and on tank walls. Three control tags corresponding to transformer oil levels at an oil temperature — 45, 15 and 45 ºС are applied on oil indicator glass (on a tank surface).
Tubular oil indicators are made of quartz glass.
Quartz glass possesses a number of the unique properties unattainable for other materials.
Its coefficient of thermal expansion is exclusively small.
The point of transformation and temperature of a softening of quartz are very high.
On the other hand, the low coefficient of thermal expansion of quartz causes its unusually high thermal stability.
Electric resistance of quartz is much higher, than the best silicate glasses. It does quartz by excellent material for production of the insulating elements working when heating.
