Cables are wires used for transmitting electricity, communication signals, or data, and are essential products in modern society. According to different uses and structures, cables can be classified into various categories. Here are the important product categories of cables:

1. Power cables: Power cables are used for transmitting electricity and are mainly used in power transmission lines, substations, industrial and mining enterprises, etc. Depending on the voltage level, power cables can be classified into low-voltage cables, medium-voltage cables, and high-voltage cables. Low-voltage cables are generally used for residential, commercial, and industrial electricity, medium-voltage cables are used in urban distribution networks, and high-voltage cables are used in power transmission lines.

2. Communication cables: Communication cables are used for transmitting telephone, network, and television signals, and are mainly used in communication equipment, data centers, broadcasting, and television fields. Communication cables can be classified into fiber optic cables and copper cables according to the transmission medium. Fiber optic cables have the advantages of high-speed transmission and anti-interference and are widely used in long-distance communication and high-speed networks.

3. Control cables: Control cables are used for transmitting control signals and are mainly used in automation equipment, mechanical equipment, instrumentation, etc. Control cables can be classified into shielded control cables, unshielded control cables, flame-retardant control cables, etc., and have good anti-interference performance and durability.

4. Power equipment cables: Power equipment cables are used for connecting power equipment and are mainly used in the internal connections of motors, transformers, switchgear, etc. Power equipment cables can be classified into oil-resistant cables, high-temperature-resistant cables, explosion-proof cables, etc., according to their uses and environments, and have good durability and safety.

5. Special cables: Special cables are used for special environments and purposes and are mainly used in ships, mines, nuclear power plants, and other special locations. Special cables can be classified into waterproof cables, explosion-proof cables, high-temperature-resistant cables, etc., according to their uses, and have special protective and durable properties.

In general, cables are essential products in modern society and are widely used in the fields of power, communication, and control. Different types of cables have different characteristics and uses, meeting the electricity transmission and communication needs of various places and requirements. With the continuous development and progress of technology, the variety and specifications of cables are constantly enriching and improving, providing important support and guarantee for the development and progress of modern society.
