Electrical distribution panels (cells)
APV manufactures electrical control and distribution panels exclusively for high-voltage electrical distribution stations, where AC and DC system panels are designed and completed for various accompanying power supply, connection and disconnection equipment, and protection systems in the station.
Electrical distribution panels (cells) are essential devices in electrical networks that distribute and protect power from the main sources to various subcircuits. They are often classified based on the voltage used (such as medium voltage) and the insulation material (gas or air), or based on their function (main or sub-cells).
Types of Cells and Distribution Boards
• Medium Voltage Cells
• Description: Electrical distribution panels operate on networks with voltages ranging from 6 to 24 kV.
• Types:
• Gas-insulated cells (GIS): These use gas as the insulating medium, are smaller and preferable for limited spaces.
• Air-insulated cells (AIS): These use air as the insulating medium and are used in general applications.
• Uses: Power stations, pumping stations, hospitals, and banks.
• Main Distribution Board (MDB)
• Description: They are the main power entry point into a building and distribute it to subcircuits.
• Uses: They receive power from main transformers or generators and supply power to buildings such as shopping malls, universities, and hotels.
• Ring Main Units (RMU)
• Description: A type of secondary distribution unit used to connect multiple circuits.
• Uses: Allows electrical circuits to be powered and provides alternate power paths in the event of a failure.
Components of an Electrical Distribution Panel
• Circuit Breakers:
Used to automatically disconnect circuits in the event of faults or overloads.
• Main Breakers:
A large breaker that controls the total power input to the panel.
• Busbars:
Metal strips (usually copper) that carry and distribute electrical power to the various circuits within the panel.
• Metering Cells:
Special units that connect two sections together, also known as "busbar bonding cells."
• Insulating Elements:
Components that provide insulation between different electrical components to protect against electrical leakage.
