Rubber bag transformer - STP
The STP rubber bag transformer is used to protect the dielectric oil in power transformers. It is also called a flexible separator or compensation balloon.
The STP inflates and deflates by compensating for the change in volume. It provides separation between air and oil inside the hydraulic conservator. This avoids
- oil pollution
- condensation
- oxidation
- hydrolysis
Thus, the system protects the dielectric oil from external contamination.
The flexible separator has a high mechanical strength. In addition, it is impermeable to gases, oils and water. These characteristics make this transformer conservator airbag an efficient compensator for the protection of electrical transformers.
Assembled by hot vulcanization in autoclave, no leakage is possible. We manufacture this product to measure (material, dimensions, flange and fixing brackets). This rubber bag transformer can then have different shapes according to your needs:
- cylindrical,
- rectangular,
- elliptical
- or even special shapes.
In addition, for the compensation of bolted conservators, there is the MTP rubber flexible membrane.
