Wires and cables are essential materials for home renovations, and their quality directly impacts household electricity usage. Wires are categorized by purpose into magnet wire and insulated wire (cloth wire). Cloth wire, based on its properties and functionality, comes in flame-retardant, fire-resistant, and low-smoke, halogen-free (LSZH) types, also known as environmentally friendly wire. Speaking of environmentally friendly wire, BYJ is the ultimate choice. So, what is BYJ? What are the common types of BYJ wire? Let's take a look at these two questions!
1. What is BYJ Wire?
1. BYJ stands for cross-linked polyethylene insulated cloth wire, a type of electrical wire. It consists of one or more flexible conductors covered in a lightweight, soft sheath. It generally produces little smoke when burned and is resistant to aging and UV rays. It is widely used in crowded places such as high-rise buildings, stations, airports, and hospitals.
Cross-linked polyethylene insulated wires must comply with the performance requirements of GB5023-1997, GB12706-1991, and JB-8734-1998. Many architectural design firms in my country are raising their standards for building wiring.
Especially after joining the WTO, and in accordance with market access principles, my country's economic development efforts will be further strengthened, the construction market will expand, and relevant building regulations will become increasingly stringent. Government departments have begun recommending the use of BYJ wires in public buildings.

The above is the basic knowledge about BYJ cable. As you can see, I've also expanded upon the meaning of BYJ cable. I'd also like to provide some additional common sense when choosing wire, focusing on the markings, insulation, copper core quality, and copper core diameter. I'll expand on this knowledge later, including explanations of other types and specifications of wire and cable.
