Understanding China’s Electrical Wire Color Code

If you’re looking to do any wiring in China, it’s important to understand the colour code used. With the right information, you can ensure that everything is installed correctly and safely. China uses a different wiring colour code than most countries in the world. This can be confusing for someone who hasn’t done a lot of wiring in the past or is unfamiliar with Chinese electrical systems. To help, we’ve put together a guide to understanding China’s wiring colour code.

Overview of China’s Wiring Colour Code

In China, the wiring colour code is based on the national standard GB/T 699-2008. This standard defines the colour codes for various wires and cables, as well as the voltage and current ratings of the system. The colour codes consist of three main colours: black, red, and green.
– Black: Used for neutral wires, often connected to ground.
– Red: Used for live/hot wires.
– Green: Used for earth wires.

Other colours may be used for specific applications, such as electric motors, but these are the three main colours. Understanding these codes is crucial for ensuring safety and compliance with regulations.

Technical Features of Electrical Wires in China

When dealing with electrical wiring, it’s essential to understand the technical features that differentiate various types of wires. Below is a comparison table highlighting key technical features of electrical wires used in China.

Feature	Description
Insulation Material	PVC, XLPE, or rubber insulation for different applications.
Voltage Rating	Commonly rated for 300/500V, 450/750V, and higher for specialized cables.
Conductor Type	Copper or aluminum conductors, with copper being more common for residential use.
Temperature Rating	Typically rated for -20°C to 90°C, depending on insulation type.
Fire Resistance	Some cables are fire-rated, suitable for high-risk environments.

These features are essential for selecting the right wire for specific applications, ensuring safety and efficiency in electrical installations.

Types of Electrical Wires in China

Different types of electrical wires are used for various applications in China. Below is a comparison table of the most common types of electrical wires.

Type	Description
