METAL ENCLOSED SWITCHGEARS

Tested MV Equipment in our improved high-tech laboratories:

ASTOR AS36 SERIES 36Kv air-insulated metal enclosed modular cubicles are designed for places: energy production facilities, substations, wind, solar power plants, hotels, shopping centers, business centers, hospitals that cannot tolerate energy cuts. These are medium voltage switchgear devices which are produced in accordance with IEC standards by completing the necessary certifications as a result of R & D studies, aiming to ensure the safety of life and property of people as well as operating characteristics by controlling energy.

We have different types of cubicle designs with functional features required for MV distribution systems.

STRUCTURAL ADVANTAGES

• Suitable for remote monitoring and control systems

• Safe switch and break operations with ASTOR brand SF6 Load-Break Switch, SF6 Disconnector Switch and SF6 Circuit Breaker.

• Convenient and safe usage in MV Distribution Transformer Substations (Concrete Monoblock Centers, Metal Enclosed Monoblock Centers) with compact dimensions

• Expandable to right and left, easy assembly and disassembly according to modular structure logic

• Mechanical interlocks designed to prevent false opening / closing operations
