Understanding Chinese Electric Wiring Symbols PDF - A Comprehensive Guide

The electrical wiring symbols used in China can be confusing for those who are unfamiliar with them. Wiring diagrams and symbols are essential tools for understanding the electrical systems of a building or appliance. Understanding the Chinese electric wiring symbols is critical to successful electrical installations, troubleshooting, and repair. In this article, we will explore the wiring symbols and diagrams associated with Chinese electric wiring.

Wiring diagrams are invaluable when attempting to diagnose and repair complex electrical systems. They are also valuable when installing and troubleshooting new systems. While wiring diagrams often depict large numbers of circuit components, some areas may require specific knowledge of electrical theories, regulations, and safety precautions. Before proceeding, it is important to familiarize yourself with the basic symbols used in Chinese wiring diagrams.

Chinese Electric Wiring Symbol Basics

Chinese electric wiring symbols depict the type of circuit, the components connected to it, and their relative locations. The symbols used in wiring diagrams are divided into three main categories: operating symbols, drawing symbols, and connection symbols. Operating symbols are used to represent the various devices and components that make up the circuit, such as resistors, switches, and other components. Drawing symbols are used to show how the components are to be connected. Connection symbols are used to show how the components are to be connected to each other.

Interpreting Chinese Electric Wiring Diagrams

Interpreting Chinese electric wiring diagrams requires an understanding of the various symbols used, as well as the underlying electrical principles. For example, the symbol for a switch may look like a triangle with a line through it, while a resistor may look like an upside-down U with an S inside. To understand what these symbols mean, you must first understand the underlying electrical principles.

In addition to circuit components and connections, electric wiring diagrams also include other information. This includes the wiring's voltage, current rating, and insulation requirements. This information is typically found in a separate key or legend. It is important to understand this information, as it can help to ensure that the correct wiring is used for the intended application.

Safety Considerations with Chinese Electric Wiring

Electric wiring can be dangerous if not done correctly. In order to ensure safety, it is important to understand the specific codes and regulations that apply in your area. Additionally, it is important to use proper protection equipment when installing or troubleshooting wiring. This includes insulated gloves, goggles, and other protective gear.

Furthermore, it is imperative to ensure that the wiring diagrams are accurate and up-to-date. Faulty wiring diagrams can lead to serious consequences, such as malfunctioning circuits, fire hazards, and even electrocution. Therefore, it is essential to make sure that the wiring diagrams are accurate and up-to-date before beginning any work on the electrical system.


Chinese electric wiring symbols are essential for understanding the functioning of any electrical system. By understanding the symbols used in wiring diagrams, as well as the electrical principles behind them, it is possible to successfully install, troubleshoot, and repair complex electrical systems. Furthermore, it is important to pay attention to safety considerations when working with electrical wiring, as faulty wiring can result in serious consequences.
