| Since 1961, PRONAL has been producing technical flexible products - both standard and custom-designed - made from fabrics coated with elastomers and plastomers, dedicated to lift, to store, to plug and to secure. |
| We’re the historical manufacturer of flexible bladders that compensate oil volume variation in your conservator. They allow to protect oil contact with the air, and thus avoid its contamination.For the Winding department, we provide inflatable lifting bags used between the different layers of the winding to adjust spacers height or positioning.Also, we provide your industry with flexible tanks to store dielectric oil during commissioning & maintenance operations on transformers. |

| Smart air cell conservator compensator |
| PRONAL STP bladders are installed within the power transformer oil conservator to protect the oil against external contamination. When oil level varies, it autonomously inflates with atmosphere pressure so as to compensate oil volume variation. Thus, dielectric oil is never in contact with external air & protected against pollutants. A device capable of detecting the rupture of the rubber membrane can be added to the STP. |
| VTR inflatable lifting bags for coil specialists |
| These lifting bags are used between the different layers of the winding to adjust spacers height or positioning without causing damages on the insulation paper. |
