Common description

Type-masted unitized transformer substation (UTSm) are powered by 25, 40, 63 and 100, 160 kVA with the voltage of 6(10)/0,4 kV of the three-phase alternate current with the frequency of 50 Hz and poses the transformer substation of the dead-ended type of the external installation. UTSm designed for electric energy admission, transformation and distribution with the airy or cable entries, earth and neutral transformer connected on the low voltage. In UTSm phase-to-phase fault protection and phase-to-ground fault are provided.

The utilization field: as a network and consumer substation on a gas and petrol field, fuel stations; in the agricultural networks and other objects of the same capacity, which are identical in electric supply conditions; in special towns and small industrial objects.

UTSm is installed on the reinforced-concrete poles (does not go with the delivery complete) with a height over ground not less than 1600mm; with the equipped operational platforms. UTSm is connected to transmission line by the driven disconnect RLNDz switch, which is supplied with the substation and is installed on the nearest bearing.

The substations guarantee active and reactive metering. On the Consumer’s demand the installation of the indicators of any modification and discharge of the UTSm with the feeder of the street lighting which is turned on automatically according to a single light relay are possible.
