Distribution of energy. Traction substation "turnkey" Metro and Light rail transport overhead line power supply equipment 
- high degree of unification and reliability,
- dimensional parametres decrease,
- repair-and-renewal operations time decrease,
- easiness in service and handling safety.
Switchgear with Shorting Contactor is interchangeable with contactor cabinets used on existing metro lines.
Design
Switchgear with Shorting Contactor is manufactured in RITTAL (Germany) casing and is a one-side serviced complete device, including contactor, protection and lighting devices.
Structurally switchgear consists of a cabinet and base. Power contactor and control elements are installed in the cabinet. Base is provided for cabinet installation on its proper location.
Power cables are ingoing into the cabinet from below.
Switching of contactor is done automatically in case of voltage supply from substation feeding line to contact line of rolling stock maintenance inspection track section. Connection of contactor to control system is provided with double-pole automatic circuit-breaker.
Power supply to contactor coil is 220 V, 50 Hz.
IP-54 protection class.
