During the past several years of product development the focus was on the compact, cost-efficient design and the longtime reliability of the device. The switch elements have been constructed completely separated from the oil circuit. That prevents leakage and makes the device very easy to maintain in built-in condition without the need of lowering the oil level.
In addition, the MBP Buchholz Relays come with our well-established UV and corrosion resistant SOLIDLINE coating.
The Buchholz relay can be equipped with a gas sampling device to get probes from the ground.
