Maintenance

Maintenance intervals depend on the components included in the station and the intervals specified by components suppliers. The level of maintenance is also influenced by the outdoor environment the station is located in. Stations in demanding environments require more maintenance.

Lifetime

The lifetime of a transformer station depends on the various components it comprises. Station care and maintenance increase its lifetime. The outdoor environment where the station is located also has a bearing on lifetime. Examples of demanding environments that shorten lifetime are damp surroundings, salt exposure on stations close to the sea, stations in agricultural environments or nearby factories with "dirty air". We calculate the normal lifetime to be forty years.

Station siting and construction

The location for the station must have a stable, levelled bed sized to accommodate the station's base dimensions plus one meter. We recommend that foundations around the station consist of medium or coarse gravel. Refer to the separate setting-up instructions.

Station location is of great importance in preventing future damage. A high location with good foundation drainage provides good conditions for the station to enjoy a long service life without mechanical or electrical problems.

Transformer installation on site at set-up
Place the base of the transformer compartment on the bed to support the transformer's weight. If it was not factory installed supporting beams are included in the delivery to act as transformer mountings. In this case it is the ground that supports the weight of the transformer.

Factory-installed transformer
The transformer is factory-installed on steel supports integrated into the station base. Contact Holtab for further information about station models.
