Wdz is a new type of environmental protection cable, which has the characteristics of low smoke and no halogen release, and is widely used in the fields of construction, transportation and communication. According to different purposes and performance requirements, wdz can be divided into several different categories.

According to the use of cables, wdz can be divided into two categories: power cables and communication cables. Power cables are mainly used to transmit and distribute power, and communication cables are used to transmit communication signals. These two types of cables are different in material and structure, but both have the characteristics of low smoke and no halogen, so as to improve safety and environmental protection.

According to the conducting medium of cables, wdz can be divided into two types: copper core cables and optical cables. Copper core cable uses copper as conductor material, which is suitable for transmitting power and signals. Optical fiber cable uses optical fiber as the conductive medium, which can transmit high-speed and large-capacity optical signals. These two kinds of cables play an important role in different application scenarios and requirements.

According to the flame retardancy and fire resistance of cables, wdz can be divided into two types: flame retardant and fire resistant. Flame-retardant cables can slow down the spread of fire and reduce the threat of fire to personnel and equipment. Fire-resistant cables can maintain normal working conditions for a certain period of time in case of fire, ensuring the reliability of power supply. These characteristics make wdz widely used in high-rise buildings, subway tunnels and other places with high requirements for fire protection.

According to the voltage grade of cables, wdz can be divided into two types: low-voltage cables and high-voltage cables. Low-voltage cables are suitable for places with rated voltage below 1KV, such as houses and commercial buildings. High-voltage cables are suitable for places with rated voltage above 1KV, such as industrial workshops and power stations. These two kinds of cables are different in material selection and structural design, but they both have the characteristics of low smoke and no halogen to improve safety and reliability.

Wdz is classified by use, conducting medium, flame retardancy, fire resistance and voltage grade. Different types of wdz have different characteristics and application scenarios, but all of them are based on environmental protection characteristics such as low smoke and halogen-free release, so as to provide safer and more reliable power transmission and communication services.
