The UniGear 500R range of medium voltage (MV) primary metal-clad air insulated switchgear has been developed specifically by ABB to meet the needs of customers requiring the simplicity, lower cost and smaller installation footprint offered by a fixed circuit breaker panel. At just 500mm wide, the UniGear 500R represents a significant space saving compared with standard switchgear panels, especially in typical applications where banks of 10 or more panels are installed. The panels can be rear wall mounted if required and are ideal for containerised substations.
Maximum safety and reliability
The UniGear 500R panel ensures maximum safety and reliability, with mechanical interlocks between the circuit-breaker, three-position line disconnector and cable testing device. All components can be accessed directly from the front, so there is no need for rear access for maintenance and service operations. The panel incorporates ABB’s well proven Vmax vacuum circuit breaker in a special fixed version – if a problem should arise it can be replaced in less than 90 minutes.
Based on a well proven design
The UniGear 500R has evolved from the well proven UniGear ZS1 range launched by ABB in 2004 to provide the world’s first ‘one size fits all’ platform for primary MV air-insulated switchgear in the 12 to 24 kV range. It is manufactured at ABB’s focused factory in Brno, Czech Republic which is currently producing over 1,000 panels a month to meet the regional demand for UniGear equipment.
ENA approved
The UniGear 500R has a certificate confirming it meets the ENA Technical Specification ENATS 41-36 covering distribution switchgear up to 36kV for use by UK DNOs (Distribution Network Operators). In its ENA version, the UniGear 500R is rated for voltages up to 12 kV and feeder currents up to 1250A – approval for the 2000A rated model is expected shortly. The UniGear 500R also complies with the IEC 62271-200 standard for metal-enclosed switchgear.
Flexible connectivity
UniGear 500R panels offer a high level of flexibility to accommodate both traditional and IEC 61850 based protection and control solutions. In the IEC 61850 enabled format the UniGear 500R incorporates ABB Relion® IEDs (intelligent electronic devices), such as the REF615 feeder protection relay, that meet the highest GOOSE (Generic Object Oriented Substation Event) performance requirements for tripping applications in distribution substations.
A wide range of applications
Over 250 UniGear 500R panels have already been installed in a number of UK applications that require a compact, space-saving, low-maintenance solution, such as data centres, wind farms, industrial projects, hospitals and major sporting venues.
One-stop shop for MV distribution switchgear
An important advantage of the UniGear 500R is it coordinates perfectly with the complete UniGear ZS1 portfolio enabling ABB to offer a complete ‘one-stop shop’ approach for MV distribution switchgear. This makes it possible to specify on the same busbar, a UniGear ZS1 with withdrawable incomer, a UniGear 500R removable circuit breaker outgoing and a motor control centre (MCC).
