Electrical cabinets: types and applications in industry

Electrical cabinets are crucial for achieving energy efficiency as they enable control, adaptation, and optimization of electrical systems.


The growing awareness of the importance of energy efficiency is becoming an inevitable component both in everyday business and in industrial sectors.

Electrical cabinets, as an important factor in energy efficiency, are enclosures that contain electrical components and equipment used for the control, distribution, and management of electrical energy within the facility or system.

The purpose of electrical cabinets is to enhance energy efficiency by providing a centralized and organized space for critical components such as switches, relays, transformers, and control systems.

Multiple types of electrical cabinets serve different applications in industries. For instance, control electrical cabinets are used to manage complex systems, enabling the automation of various processes. On the other hand, distribution electrical cabinets are employed for distributing energy within buildings.

Types of electrical cabinets

Control electrical cabinets

Control electrical cabinets are used for overseeing and managing various processes and systems in industries and facilities.

Furthermore, a control electrical cabinet contains electronic components and equipment for automation and management to achieve desired objectives or functionalities of investor.

Control cabinets are used in numerous industrial processes such as manufacturing, automation, transportation, and energy. Moreover, they enable precise control and supervision over processes, increasing efficiency, reliability, and safety.

Practical application:

Control cabinets play a pivotal role in industrial facilities, enabling centralized control, supervision, and automation of diverse processes. Their applications span control of production lines, regulation of temperature and humidity in warehouses, management of pumps and valves in plumbing systems, and automation of procedures in energy plants. These are just one of many applications of control electrical cabinets.

For instance, control cabinets are utilized in the transportation sector to control signaling and monitor the status of traffic systems, providing efficiency, reliability, and quick response to changes in the working environment.

MCC cabinets (Motor Control Center)

An MCC electrical cabinet is designed to manage and protect electric motors in industrial environments. The electrical cabinet contains components that facilitate precise motor starting, stopping, speed regulation, and protection, ensuring reliable and safe operation. MCC cabinets play a key role in enhancing and maintaining the efficiency of industrial processes.

Practical application:

MCC cabinets are instrumental in minimizing downtime, extending the lifespan of motors, and facilitating maintenance and diagnostics.

They are commonly used across various industrial sectors, including manufacturing, energy, petrochemicals, and mining. They are primarily used to control various electric motors, such as pumps, fans, conveyor belts, compressors, and other devices, ensuring optimized functionality and efficiency of production processes.

PLC electrical cabinets

PLC (Programmable Logic Controller) electrical cabinets are designed to house and protect PLC controllers – industrial computer devices programmed to control and automate various processes. Furthermore, a PLC electrical cabinet is equipped with components like power supplies, input/output modules, communication interfaces, and wire connections needed to operate the PLC system.

They provide a secure and organized environment for the efficient functioning of PLCs within industrial settings.

Practical application:

PLC electrical cabinets find widespread application in industrial automation across various sectors, including manufacturing, energy, and infrastructure. They automate tasks such as managing production lines, equipment operation, environmental condition regulation, and safety system monitoring. By facilitating efficient control and coordination of complex processes, PLC cabinets contribute to increased productivity, improved product quality, reduced downtime, and enhanced safety measures in industrial operations.

Electrical distribution cabinets

Electrical distribution cabinets are highly specialized cabinets focused on precise management and control of reactive power within electrical systems. Reactive power, alternating between sources like generators and consumers, is characterized by fluctuating nature that, despite its presence, doesn't perform useful work.

Electrical distribution cabinets are devised to mitigate this unproductive load and ensure optimal utilization of the electrical grid. Additionally, they allow efficient management and optimization of reactive power to enhance energy efficiency and reduce costs.

Practical application:

Distribution cabinets play a crucial role in industry and commercial premises to ensure optimal use of electrical energy, reduce losses, and improve energy efficiency.

Furthermore, they are applied in industrial plants and commercial buildings to efficiently manage electro-energy systems. They enable active correction of reactive power, thereby improving the power factor, reducing grid losses, and enhancing energy efficiency.

This system decreases the overall consumed electrical capacity, improves the power factor, and optimizes energy consumption, thereby lowering energy costs and enhancing the efficiency of the electrical system.

Electrical cabinets for telecommunications

Electrical cabinets for telecommunications are designed to protect highly sophisticated telecommunications equipment from potentially harmful external factors. Key to housing and preserving devices such as routers, switches, and telephone equipment, ensuring not only physical security but also continuous, reliable communication and seamless data transfer. Their specialized role makes them indispensable elements of the infrastructure that supports the stability and functionality of modern telecommunications networks.

Practical application:

Telecommunications cabinets are crucial for ensuring the safe and reliable functioning of telecommunications systems.

They play a key role in mobile networks, fixed telephony, broadband services, data centers, cable, and fiber optic networks, and facilitate wireless services, mission-critical communications, and video surveillance networks. In this way, they enable reliable and efficient communication, signal distribution, and Internet access in different environments.

Electric cabinets for compensation of reactive energy

Electrical cabinets for reactive energy compensation represent highly specialized cabinets aimed at precise management and control of reactive energy within electrical systems. Reactive energy, alternating between a source, such as a generator, and a consumer, is characterized by an oscillating nature that, despite its presence, does not perform a useful workload.

Reactive energy compensation cabinets are designed to suppress this unproductive load and ensure optimal utilization of the electrical network. In addition, they enable efficient management and optimization of idle energy to improve energy efficiency and reduce costs.

Application in practice:

Reactive energy compensation cabinets play an important role in industry and commercial facilities to ensure optimal use of electrical energy, reduce losses and improve energy efficiency.

Furthermore, reactive energy compensation cabinets are used in industrial plants and commercial buildings for the efficient management of power systems. They enable the active correction of reactive energy, which improves the power factor, reduces losses in the network, and increases energy efficiency.

This system reduces the total consumed electrical capacity, improves the power factor, and optimizes the consumption of electrical energy, thereby reducing energy costs and increasing the efficiency of the electrical system.
