What does wdz-yjy cable mean?

　　WDZ-YJY cable is a low-SMoke halogen-free flame retardant cable, its full name is copper core conductor XLPE insulated halogen-free low-smoke flame retardant polyolefin sheathed power cable. The following is a detailed explanation of WDZ-YJY cable:

　　First, the meaning of the cable code

　　WD: means halogen-free low smoke, that is, the cable releases very little smoke when burned, and does not produce toxic or corrosive gases, which is environmentally friendly.

　　Z: indicates flame retardancy, that is, the cable has excellent flame retardant properties, which can prevent the spread of fire to a certain extent.

　　YJ: indicates cross-linked polyethylene insulation, which has high heat resistance and mechanical strength and is a commonly used insulating material in power cables.

　　Y: indicates polyethylene sheath, which has excellent weather resistance and corrosion resistance and can protect the cable from external environmental damage.

　　II. Structural features

　　Conductor: High-conductivity copper core conductor is used to ensure that the cable has good electrical conductivity.

　　Insulating layer: Using cross-linked polyethylene as an insulating layer, it has excellent heat resistance and electrical properties, and can maintain stable electrical properties in high temperature environments.

　　Sheath layer: Using halogen-free low-smoke flame-retardant polyolefin as the sheath layer, it not only has excellent weather resistance and corrosion resistance, but also releases less smoke and toxic gases during combustion.

　　III. Performance advantages

　　Environmental protection: The halogen-free and low-smoke characteristics make the cable less environmentally friendly when burned, meeting the requirements of modern green environmental protection.

　　Flame retardancy: It has excellent flame retardancy, which can prevent the spread of fire to a certain extent and improve the safety of the cable.

　　High temperature resistance: The cross-linked polyethylene insulation layer has high heat resistance and can maintain stable electrical performance in high temperature environments, ensuring long-term stable operation of the cable.

　　IV. Scope of application

　　Rated voltage: suitable for power lines with rated voltage 0.6/1 kV and below for transmission.

　　Application scenarios: Widely used in high-rise buildings, subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical and other places, as well as areas with high concentration of personnel and low air density, to ensure safe power supply in emergency situations.

　　In summary, WDZ-YJY cable is a low-smoke halogen-free flame retardant cable with excellent performance, suitable for a variety of power lines and transmission and distribution occasions, and is an indispensable and important component in modern power systems.
