Basic Overvie
Low-voltage distribution cabinets are important equipment for receiving and distributing low-voltage electric energy in power systems, and are usually installed at the starting end of low-voltage power grids. According to the structural form, low-voltage distribution cabinets can be divided into fixed, drawer, power-controlled and combined types. Fixed low-voltage distribution cabinets are suitable for places with simple distribution lines and fewer transformers.
drawer-type low-voltage distribution cabinets are easy to repair and replace, and are suitable for places with complex distribution lines; power-controlled low-voltage distribution cabinets are mainly used to control the start, stop and reverse operations of motors; combined low-voltage distribution cabinets integrate multiple functions together, and are suitable for places with high power distribution requirements.
Advantages And Characteristics
High safety: The internal circuits of the distribution box are insulated to effectively prevent external interference and short circuits, and better protect personnel safety. In addition, it also has electrical safety protection functions such as leakage, overcurrent, and overvoltage.
Compact size: The Efficient and energy-saving mall distribution cabinet integrates the original circuit control parts according to certain standards, with a small size, easy installation, no site constraints, and convenient inspection and control.
Intelligent management: The intelligent distribution box introduces mobile internet technology, which can be remotely accessed through mobile phones PAD、 Real time monitoring and management of various electrical lines in the home by computers, timely detection and handling of electrical faults.
High protection level: Intelligent monitoring system for distribution cabinet are usually made of high-quality materials, with a tight overall structure and good protection performance, which can effectively prevent power safety accidents such as leakage, arc, short circuit, and overload.
Stable and reliable operation: During normal operation, the circuit can be connected or disconnected using manual or automatic switches; When there is a malfunction or abnormal operation, use protective appliances to cut off the circuit or sound an alarm; Measuring instruments can display various parameters during operation, adjust certain electrical parameters, and provide prompts or signals for deviations from normal working conditions.
1 Phase vs 3 Phase Electricity：
3 phase power works by having three alternating currents with a 120 - degree phase difference. This creates a rotating magnetic field. Motors use this field to turn. In power transmission, it's more efficient as the phases balance each other, reducing losses. The three voltages work together to supply continuous power to drive high - power equipment.

Application areas
Manufacturing industry: Production equipment, automated assembly lines, CNC machine tools, etc. in various factories require stable and reliable power supply. Distribution boxes distribute power to various production equipment and have functions such as overload protection and short circuit protection to ensure the normal operation of equipment and prevent production interruption or equipment damage caused by electrical faults.
Public buildings: Schools, hospitals, libraries, sports centers, subway stations, and other public buildings require a large amount of electricity to maintain daily operations, such as lighting, medical equipment operation, elevator operation, fire protection systems, etc. The distribution box is responsible for the reasonable distribution and protection of this electricity.
Mining industry: used in mines to provide electrical support for ventilation equipment, drainage equipment, lifting equipment, lighting systems, etc., ensuring the safe and efficient operation of mining operations.
Highways and railways: provide power support for streetlights, signal lights, toll station equipment, railway communication equipment, and power supply systems for electrified railways, ensuring smooth and safe transportation.
Construction industry: Various construction machinery, temporary lighting, welding machines and other equipment on construction sites need to be connected to the power supply through distribution boxes. At the same time, some large construction projects also set up temporary distribution boxes to facilitate power management and distribution during the construction process.
