The factory electrical system plays a crucial role in supplying and managing power for the operation of equipment and production lines. Designed comprehensively, it includes essential devices and subsystems to ensure stable and safe operation.
What is a factory electrical system?
A factory electrical system provides and distributes the primary power supply to the entire facility, ensuring stable and efficient operation of machinery and production lines. Key components of the system include: Distribution Panels, Transformers, Power Cables and Electrical Protection Devices: Such as circuit breakers, automatic circuit protectors (ACBs), and grounding systems.
Overview classification of factory electrical systems
Factory electrical systems can be broadly categorized into three main types based on functionality.
Main power supply system
The Main power supply system accounts for the largest proportion of value and workload in the factory electrical system. It supplies power to high-capacity equipment, such as industrial machinery, forming the foundation for operating production lines. This ensures optimal performance and operational stability for the factory.
Extra low voltage (ELV) System
The ELV system supports the operation of technological devices such as surveillance cameras, network systems, and fire alarms. It enhances security and facilitates internal management.
Lighting system
The lighting system is essential for providing adequate illumination to work areas, warehouses, and other zones, ensuring productivity and safety.
Key components in factory electrical system
Main switchboard (MSB)
The MSB is the main electrical panel in a factory’s power distribution system. It distributes electricity from the transformer station to branch panels. Equipped with a main circuit breaker, the MSB allows for easy disconnection of power during maintenance, repairs, or emergencies, ensuring safety. Additionally, the main breaker protects smaller circuits by preventing issues such as overloads or short circuits.

Distribution board (DB)
The DB is a critical component responsible for distributing power from the MSB to specific areas or equipment. Commonly used in factories, buildings, or residential areas, the DB ensures stable power supply tailored to various needs. It features circuit breakers and protection devices to prevent overloads or electrical faults while allowing for easy isolation of power for maintenance or repairs.

Generators
Generators are indispensable in factories, buildings, or residential areas, providing backup power during grid outages. They convert mechanical energy into electrical energy to ensure uninterrupted operation of essential systems such as production lines, machinery, fire protection systems, and lighting.

Transformers
Transformers regulate high-voltage electricity from the grid into medium or low voltage, suitable for use in factories, buildings, or industrial parks. They serve as an essential intermediary, ensuring stable and safe power supply, preventing damage to electrical equipment. Besides, transformers enhance energy efficiency and minimize power losses.

Electrical cables
Electrical cables are essential for transmitting power from the source to devices or specific areas. Designed for high load capacity and resistance to harsh environmental conditions, these cables ensure stable and safe electricity transmission. Cable quality directly impacts the efficiency of the electrical system, making the selection of appropriate cables crucial. Moreover, cables must be installed neatly and protected to minimize risks such as short circuits, fires, or damage during use.

Lighting system
The lighting system is a critical part of the electrical infrastructure, providing illumination for work areas, corridors, warehouses, and other spaces in buildings and factories. Adequate and stable lighting plays a vital role in ensuring workplace safety, improving productivity, and creating a conducive environment for production activities. Avoid common mistakes in factory lighting design. A scientifically designed lighting system not only enhances energy efficiency but also helps reduce operating costs.

Control and protection devices
Control and protection devices such as fuses, relays, and circuit breakers are designed to automatically disconnect the power supply when issues like overloads, short circuits, or electrical leakage are detected. Control and protection devices are crucial for ensuring user safety, minimizing equipment damage, and preventing fires in the factory’s electrical system.
Grounding system
The grounding system is a critical safety measure, particularly in areas with high-powered electrical equipment like factories or industrial buildings. Its main function is to direct electrical leakage safely into the ground, preventing electric shocks and protecting both users and equipment. Grounding systems also reduce the damage caused by lightning strikes or high-voltage surges. Designed to strict technical standards, grounding systems enhance safety and contribute to extending the lifespan of electrical equipment.
Low-voltage electrical devices
Low-voltage devices, such as network systems, surveillance cameras, and fire alarm systems, may require less work to install but are crucial for factory operations and management. These devices directly impact connectivity, safety, and production oversight. Surveillance cameras facilitate remote monitoring, operational management, and timely detection of issues. Network systems serve as the backbone for data transmission, connecting departments and smart devices to support automation in factories. Fire alarm systems, despite being a small component, are vital for asset protection and worker safety.
