The robust and universally deployable grid substation with an attractive appearance 


 1. SUBSTATION DESCRIPTION

The GKP-S1 compact substation is a space-saving generalpurpose transformer and customer substation with a wide range of confi guration options. It is designed for use in the power range up to 630 kVA (optionally 800 kVA). The substation is manufactured in compliance with the relevant standards and regulations, including IEC, DIN, VDE and UVV, and the following standards in particular:

The substation has been successfully arc tested with all established switchgear manufacturers, including ABB, Schneider Electric, Ormazabal, Siemens and others.


2. CONSTRUCTION

The body of the station consists of two monolithically pre fabricated concrete elements (body and roof). The MV cables are fed in using a watertight entry system (eg Hauff). An open cable entry slot in the basement allows to enter with the LV cables. It is also possible to feed in the MV cables through an open entry duct with a fixed attachment plate.

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 profi le cylinders. Two-point interlocking systems for each door leaf allow the doors to be closed without any risk of arcing. The ventilation grills are
pick-proof and can be optionally fi tted with stainless steel insect screens.

4. ELECTRICAL EQUIPMENT

Fitting of the electrical equipment of the substation, including the medium voltage switchgear, transformer, low vo ltage distribution metering panel, MV and LV cables, earthing, etc. is per formed at the factory according to customer specifi cations in compliance with IEC 62271-202.

5. TRANSPORT & INSTALLATION

The substation is delivered by truck to the site as a com plete unit ready for connection and is set down in the foundation pit with the aid of a truck-mounted or mobile crane. Four lifting points in the base are provided for lifting the substation.
