Spare parts management for transformer components

A spare part is a replaceable product’s component fundamental to ensure the functioning of the system to which it belongs.Having original spare parts always at your disposal means guarantee the highest level of performance to your transformer reducing significantly the risk of failure as well as the down-time due to the maintenance.

Our spare parts portfolio covers parts for liquid-level indicators, pressure release devices, gas sampling devices, breathers, temperature indicators, porcelain and combined resin silicon bushing and safety integrated devices produced in COMEM, Montebello Vicentino, Italy. We guarantee a 100 percent of compatibility of all Spare Parts that are going to replace the defective components of your equipment and guaranteeing rialibility of your transformer.
