The CGIS switchgear is a new joint product of Mehrabad Company and DECOM of Germany. All main components of the switchgear, including the disconnector, breaker, and transformers, are placed in a metal enclosure filled with SF6 gas, which, in addition to creating high safety, eliminates the need for repairs and maintenance and prevents the ingress of moisture, dust, and oxidation into the main parts of the switchgear.

Prefabricated feeder houses are an innovative solution with unique capabilities in electrical energy distribution networks and, compared to the building type, are the most suitable choice for achieving the financial and time goals of the project.

These feeder houses, in addition to being installed in newly constructed projects, are presented as a fast and reliable solution in development plans or replacement of existing substations and are the best choice for crisis management during peak load times. Furthermore, the use of these feeder houses is recommended in wind farms, solar fields, or projects that are built at a great distance from urban infrastructure.

All the equipment of each feeder house is installed, tested, and ready for operation at the factory. Therefore, due to advantages such as reduced cost, time risk, and installation and commissioning complexities, the use of this product has always provided an acceptable experience for the customer.

One of the exclusive products of Mehrabad Industrial Company is the FULX design low-voltage switchgear. The integrated triangular profile of the columns, the bolt-and-nut structure, and the special set of connections and accessories of this switchgear, in addition to creating a distinction from other similar products, guarantee a high-quality and robust product. Features such as the industrial and intelligent design of the switchgear components in a modular form, safe connections, ease of storage, etc., while diversifying the design and dimensions, have led to a reduction in the production time of this product.

This product is used in the production of various control, protection, measurement and monitoring panels, various main and sub-distribution panels, power factor correction panels (capacitor banks) and various charger, PLC, UPS, etc. panels.

The LPGIS product is the result of a research and innovation project in collaboration with the Fulmen Group and German specialists, based on the idea of converting a 63 kV AIS substation with all the main equipment, including lightning arresters, voltage transformers, disconnectors, current transformers, and circuit breakers, into an ultra-compact switchgear. Small dimensions, minimal need for maintenance, installation of equipment using the Plug-in method, along with attention to passive defense and environmental issues in the design, are among the prominent features of this product.

The 63/20 kV LPGIS mobile substation, utilizing LPGIS and CGIS switchgear, has very compact dimensions, such that the use of this type of substation reduces the approximate 2000 square meters of space required for the construction of a 63/20 kV AIS substation to less than 110 square meters.

All 63 and 20 kV feeders and other auxiliary equipment of this substation can be accommodated in a 6.2 * 4.6 meter cabin, which, along with the auxiliary transformer, can be easily transported by a two-axle truck without concern for traffic load considerations.

Low voltage drawout switchgear is one of the most commonly used types of low voltage switchboards. Known for their high level of safety and efficiency, these switchboards are commonly used in large factories, substations, power plants, metro systems, and locations requiring a large number of consumers with varying amperages

Each output feeder, designed to supply power to consumers, is known as a drawer. Each drawer supplies a specific load, which could be an electric motor, lighting, or other electrical equipment. In essence, each drawer is a small switchboard in itself.

Communication busbars are located at the top of each cell, and fingers are used to feed the feeders, located vertically behind the output cells. Numerous equipment items are required for the installation and assembly of these switchboards

Depending on the design and client requirements, the breakers in these drawers can be simple or motorized. Motorized breakers can be controlled from a control room. The most critical part of the SivaKon design switchboards is their mechanical assembly, which is quite complex. Thanks to its brilliant history and years of experience, Mehrabad Industrial Company has been able to offer this type of switchboard to its esteemed clients.
