conservator with MTP compensation bladderconservator with MTP compensation bladder

MTP compensation bladders

The MTP compensation bladder separators bolted onto the outside (in two parts), are also known as “Josse lungs”, and used to protect the dielectric oil used in power transformers. The oil is on one side of the bladder while the other is open to the atmosphere; it allows to compensate the dielectric oil volume variation directly linked to temperature levels and protect the system from any outside contamination.

Our compensation membranes are custom made (shape, dimensions, outer drilling). They are delivered with a drain valve and two seals that ensure sealing between the bladder flanges once bolted together. Their tightness to gas, oil and water as well as their high mechanical resistance make Pronal MTP membrane a high performing  system to protect your electric power transformer.
