The high-performance compact customer substation.

The substation consists of two monolithic prefabricated concrete sections. The sections, consisting of the base tray, midsection and roof, are expertly assembled in the factory.

The exterior surface of the midsection can be finished according to the customer’s wishes. The following options are available: exposed aggregate concrete, quartz gravel, fair-faced concrete, float finish or roll-on stucco with RAL finish coat, brick tile facing, and Dupa stone.

The substation is equipped with dual double-skin hot-dip galvanised steel doors without ventilation. The doors have a four-point locking system with a lock ready for fitting a profile cylinder, or two profile cylinders on request.



VERSATILE, COMPACT LOCAL GRID AND CUSTOMER SUBSTATIONS



1. SUBSTATION DESCRIPTION
The GBÜ 1000/2000 Compact Substation is a space-saving, general-purpose local grid and customer substation with a wide range of configuration options. It is designed for use in the power range up to 1000/2000 kVA. The substation is manufactured in compliance with the relevant regulations such as IEC , DIN, VDE and UVV, as well as the following standards in particular:
The substation has been successfully arc tested with classification IAC AB 20 kA 1s 24 kV (up to 36 kV in some cases) with all commonly used makes of switchgear, including ABB, Ormazabal, Schneider-Electric and Siemens. In addition, air-insulated metering panels made by Elley and Ormazabal can be used in the arc tested version with classification IAC AB 20 kA 1s. A substation variant with SF6-insulated MV switchgear (ABB Safe Plus) and IAC AB 25 kA 1s classification is also available.

2. CONSTRUCTION
The substation consists of two monolithic prefabricated concrete sections (body and roof). The MV cables are fed in using watertight entry systems (e.g. Hauff). The LV cable can be brought in through a cable entry duct open at the bottom. An LV cable entry with a watertight entry system is available as an option. The surface finish of the substation can be individually customised to suit customer wishes. Exposed aggregate concrete, fair-faced concrete, float-finish and roll-on stucco with a choice of colours from the RAL colour card,
brick tile facing and other special finishes are available.̈

3. DOORS AND VENTILATION
All substation doors and ventilation components made by us can be manufactured from either galvanised steel or aluminium, depending on the customer’s choice. The doors are equipped with door stops, copper earthing straps and swivel lever locks for either one or two profile cylinders. Two-point locking systems for each door leaf eliminate arcing risk with the doors closed. The ventilation grilles are pick-proof and can optionally be fitted with insect screens.

4. ELECTRICAL CONFIGURATION
The electrical configuration of the substation with medium-voltage switchgear, transformer, low-voltage distribution panel, MV and LV cables, earthing, etc. is carried out at the factory according to customer specifications in compliance with IEC 62271-202.

5. TRANSPORT / INSTALLATION
The substation is delivered by truck to the job site as a complete unit ready for connection and is set down in the foundation pit prepared for it with the aid of a truck-mounted or mobile crane. Four lifting points in the base are provided for lifting the substation.
