ELEKTROBUDOWA SA with a huge experience in MV switchgears manufacturing offers a miniature two-level metal-clad switchgear D-12-2P with air insulation and rated continuous current up to 3150A which is dedicated for energy distribution in AC networks at rated voltage up to 12 kV.
D-12-2P is indoor free-standing metal-clad switchgear which is built with separated cubicles connected by busbar systems. Incoming cubicles with busbar system up to 3150 A are connected with busbar systems of outgoings by connecting box between cubicles. Outgoings to 1600 A are placed in two levels one above another. The switchgear is equipped with interlocks required by standards and additional ones. System of fast arc detecting and switching can be applied. The switchgear includes incoming cubicles D-12P type and LV cubicles NGW R type equipped with control and protecting devices for outgoing cubicles. Following version can be manufactured standard version with manual drive.
Works seamlessly with any digital control system. Auxiliary circuits compartment can be extend by additional control cubicle installed beyond the switchgear.
