The medium voltage withdrawable switchgear is a metal-enclosed (AIS) electrical panel system.
The EECSwitch system is a metal-enclosed (AIS) medium voltage switchgear system, specifically designed for secondary distribution networks.
Thanks to its compact and flexible design, this system provides a long-term technical solution for a wide range of electrical power distribution applications.
The design of this system is based on three fundamental principles: high level of safety, ease of use, and consideration of environmental requirements.
Full automation support and the use of modern protection relays make it an ideal choice for advanced applications.
Due to its modular configuration, these switchgear units offer a wide range of cell types and allow for the selection of the most optimal and cost-effective solution for each project.
The EECSwitch system is perfectly suited for various secondary distribution network applications in both industrial and public sectors.
The medium voltage switchgear is manufactured according to the UniGear ZS1 design, leveraging ABB’s technical expertise, and has undergone type tests in accordance with IEC 62271-200 requirements. These units are designed and manufactured with a nominal voltage of 24 kV, a nominal current of up to 4000 A, and a short-circuit withstand capability of up to 50 kA.
These switchgear units belong to the metal-clad category, designed for indoor installation. The system is based on a modular structure consisting of standard interconnected and mounted parts. The different compartments of the device are separated by metal sheets, and the energized compartments are air-insulated. All components have been tested according to IEC standards. For ease of use, all power cable connections are accessible from the front of the panel.
Panel compartments:
A: Circuit breaker compartment.
B: Busbar compartment.
C: Cable termination compartment.
D: Control or low-voltage compartment containing measurement, control, and protection equipment.
