Chinese Wiring Colour Codes: The Ins and Outs of Electrical Wiring Diagrams

Knowing how to read Chinese wiring colour codes is essential for anyone involved in the installation or repair of electrical wiring. Wiring diagrams – also known as schematic diagrams – provide a visual representation of the physical components and connections of an electrical system, making it easy to understand and identify. By understanding the code associated with each wire, individuals can make sense of the wiring diagram and determine which wires should be connected where. In this article, we will explore the Chinese wiring colour codes and how they can help you troubleshoot electrical wiring issues.

Understanding the Basics of Electrical Wiring Diagrams

In order to understand Chinese wiring colour codes, it is important to first understand the basics of electrical wiring diagrams. These diagrams are used to map out the physical layout of the electrical system, including all of the components that make up the electrical system. The diagrams also indicate how the components are wired together, so that electricians and engineers can quickly identify potential problems and troubleshoot them. Wiring diagrams can also be used to design new electrical systems and plan for their installation.

Using Chinese Wiring Colour Codes

When working with electrical wiring diagrams, it is important to understand the Chinese wiring colour codes. These codes are used to identify and mark the various wires and cables in the diagram. Each colour corresponds to a specific type of wire and/or cable. This makes it easy for electricians and engineers to identify which wires and cables need to be connected where in order to ensure the correct and safe operation of the electrical system.

The most common Chinese wiring colour codes are as follows:

Red: Hot (or live) power, usually carrying a voltage of 220v

Black: Neutral power, usually carrying a voltage of 0v

Blue: Ground wire, usually carrying a voltage of -2v

Yellow: Low-level signal lines

White: High-level signal lines

It is important to note that these colours are not universal and may vary based on the country or region. As such, it is always best to double-check when using wiring diagrams that include Chinese wiring colour codes.

Understanding the Symbols Used in Chinese Wiring Colour Codes

In addition to the colours used for each type of wire and/or cable, there are also symbols used in Chinese wiring colour codes. These symbols help to indicate the purpose of each wire and/or cable, as well as the direction of current flow. The most common symbols used in Chinese wiring colour codes are as follows:

Circle: Indicates a positive power source

Triangle: Indicates a negative power source

Square: Indicates a connection point

Semicircle: Indicates a ground connection

Lightning bolt: Indicates an output connection

By understanding the meanings of these symbols, it is possible to quickly identify the purpose of each wire and/or cable in the wiring diagram.

Using Chinese Wiring Colour Codes in Practice

Now that you understand the basics of Chinese wiring colour codes and symbols, it’s time to put them into practice. When reading a wiring diagram that includes Chinese wiring colour codes, make sure to pay close attention to the colours and symbols used for each wire and/or cable. This will help you quickly identify which wires and cables need to be connected where, and ensure that your electrical system is correctly and safely wired.

In conclusion, being familiar with Chinese wiring colour codes is an important skill for anyone involved in the installation or repair of electrical wiring. By understanding the meaning behind the colours and symbols used in these codes, you can quickly identify the purpose of each wire and/or cable in the wiring diagram and ensure that your electrical system is correctly and safely wired.
