Water is a dangerous enemy of the transformer, reducing the dielectric strength of transformer oil, accelerating the aging of oil and solid insulation. It is impossible to entirely prevent water contamination in a transformer, since it forms regardless of service quality and airtightness of the unit. However, it is possible to protect the transformer with the CMM-260C continuous drying device. This machine is connected to the transformer and keeps it dry throughout its service life by passing its oil through a microporous granular sorbent. Water is absorbed and reliably held in its crystals.
If necessary, the adsorbers can be easily dismantled and replaced with new ones, or the sorbent can be reactivated using the BRPS (BRZ) zeolite regeneration unit.
