Medium voltage pull-out switchgear is an air‑insulated metal (AIS) electrical switchboard system.
The EECSwitch system is an air‑insulated metal medium‑voltage switchgear (AIS) system, specifically designed for secondary distribution networks.
Thanks to its compact and flexible structure, 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 core principles: a high level of safety, ease of use, and consideration of environmental requirements.
Its support for full automation and the use of modern protective relays also make it an ideal choice for advanced applications.
Thanks to its modular configuration, these switchgear units offer a wide range of cell types, allowing 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, both in the industrial and public sectors.
The medium‑voltage switchgear is manufactured leveraging ABB’s technical expertise, according to the UniGear ZS1 design, and has undergone type testing in compliance with IEC 62271‑200 requirements. These units are designed and produced with a rated voltage of 24 kV, a rated 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, intended for indoor installation. The system is based on a modular structure composed of standard interlinked and assembled parts. The different compartments of the device are separated by metal plates, while the energized parts 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.
