Power, Line Cables and Extension Cords
This column focuses on cables and accessories related to power transmission and connection. They are essential basic connection components in electronic systems. Applicable specifications and certified products should be selected in combination with application scenarios.
1. What are Power, Line Cables and Extension Cords?
Power Line Cables: Wires used to transmit current, usually composed of conductors (such as copper, aluminum and other metal materials) and insulation layers (such as PVC, rubber, etc.). Common specifications include 16AWG, 18AWG, etc., suitable for different current carrying requirements.
Extension Cords: Portable cables with plugs and sockets are used to extend the power connection range and support the long-distance power supply of devices.
2. Where are Power, Line Cables and Extension Cords Used?
Current Transmission: Provides stable power input for electronic devices (such as computer hosts, monitors, household appliances, etc.) to ensure normal operation of the equipment.
Connection Extension: Use extension cables to solve the problem of power interface distance limitation, which is common in home, industrial and office scenarios.
3. How to Choose Power, Line Cables and Extension Cords?
Materials and Processes: Must comply with safety standards such as fire prevention, high-temperature resistance, and wear resistance, such as UL certification, VDE certification, etc., to ensure reliability.
Electrical Parameters: Including rated voltage (such as AC 100-240V), current capacity (such as 10A/16A), etc., which must match the equipment requirements.
4. Classification Attributes for Power, Line Cables and Extension Cords
Passive Components: Passive devices that only have the function of power transmission and do not have the ability to amplify or control signals.
Connector Branch: Classified as electromechanical components (such as connectors and switches), emphasizing physical connection and electrical conduction characteristics.
