Metal Enclosed Switchgear
These are medium voltage switchgear devices designed for use in secondary distribution systems up to 36 kV, in compact kiosk-type transformer buildings and in industrial facilities, for indoor applications. All functional units that may be required in a switchgear center can be easily installed side by side. The switchgear, which is completely manufactured in the factory and has undergone all routine type tests, can be safely used and put into operation practically in a very short time.
Separation and breaking operations are carried out in an SF6 gas environment and the busbars are air-insulated. In this way, a safe separation and breaking process is ensured and the dimensions are minimized. Modular switchgear, with their compact dimensions, can be used comfortably and safely in kiosk-type transformer centers.

Operational Ease and Reliability
Metal Enclosed switchgear systems are user-friendly medium voltage distribution units designed to ensure safe and easy operation. The cell structure, which has passed internal arc withstand tests, maximizes operator safety in case of a fault. The earthing switches, capable of closing onto short circuits, enable the system to be safely grounded during maintenance and switching operations.
Disconnector and load break switch mechanisms are equipped with mechanical and electrical interlock systems to prevent incorrect operations and ensure that switching is performed in the correct sequence. Voltage indicators on the switchgear provide a visual reference for the status of energized cables, offering additional safety before intervention.
Each compartment of the switchgear is isolated from one another with sheet metal partitions. This structure prevents a fault in one compartment from spreading to others. Mimic diagrams supported by position indicators offer the operator a clear and quick overview of the current system status. In addition, the low maintenance requirements of operating mechanisms contribute to long-term and uninterrupted system operation.
Its modular structure allows for easy expansion and integration with various systems. Thanks to pre-tested and pre-assembled components, commissioning is accelerated and error risk is minimized. When combined with a safe grounding system and an enclosure isolated from environmental influences, Metal Enclosed switchgear offers both operational convenience and high safety standards.
