Ürün Bilgisi
Metal enclosed modular switchgears are medium voltage switchgears designed for use in MV distribution systems, compact power center type substations and industrial plants, designed for use in internal spaces, used for reliable distribution of electricity, manufactured in accordance with IEC standards. Metal enclosed modular switchgears are manufactured from 12 kV to 36 kV. All functional units that may be required in a switchgear center can be easily installed side by side.
Metal Enclosed Modular Switchgear Sections
Air Insulated Modular cell types consist of 3 main sections. These sections are secured by switching and mechanical interlocks, and the transitions to ensure continuity. They are isolated from other sections.
A) Busbar Connection Section:
This section is where the main busbar is located and the main busbar connection is made. This section contains electrolytic coppers, insulators and bushings. Busbars can be aluminum or copper. The breaker may vary according to the rated current value. Access to this section requires special instructions and safety precautions.
B) Cable Connection and Switching Section:
This is the section where medium voltage cables are connected. Earthing separator, breaker, support insulator, capacitive insulator, current transformer, voltage transformer, MV fuse, earthing busbar are located in this section. For safe access to this section, the earthing disconnector must be closed in the earth position.
C) LV section:
This section contains terminal blocks, LV fuses, thermostats, measuring instruments and protection relays. While the cell (busbars and cable) is energized, operations can be performed in the LV panel.
Areas of Use
MMH series metal enclosed switchgears are highly preferred products in medium voltage electricity distribution networks. Easy installation, expandable structure, diversity in product types make it preferred in many branches of the industry. Project-specific solutions, flexible design and production structure are also among the reasons that affect this preference. It is one of the most preferred products in electricity distribution systems with its safe use and maintenance-free structure. It is preferred in places where people live mostly. Main areas of use;
