Ten common cable types include:
Power cables: The workhorse of power transmission, responsible for delivering electricity from power plants to homes. Based on voltage levels, they can be categorized as low-voltage, medium-voltage, high-voltage, and ultra-high-voltage cables.
Control cables: Used for controlling, monitoring, and protecting circuits, they are commonly found in automation equipment, instrumentation, and other applications. They feature multiple cores, a small cross-sectional area, and excellent anti-interference performance.
Communication cables: These include coaxial cables, twisted-pair cables, and fiber-optic cables, responsible for transmitting signals for telephone, internet, and television.
Computer cables: These connect computers to external devices, such as USB cables, HDMI cables, and network cables, and affect the efficiency and stability of data transmission.
RF cables: Used for transmitting high-frequency signals, such as those for radio, television, and radar, they effectively minimize signal attenuation and external interference.
Fiber-optic cables: Utilize light pulses to transmit information, offering advantages such as long transmission distances, high capacity, and strong anti-interference capabilities.
Fire-resistant cables: These cables maintain power supply for a certain period of time even in the event of a fire and are widely used in high-rise buildings, subways, airports, and other important locations.
Flame-retardant cables: These cables prevent flames from spreading and are commonly used in crowded places and power supply lines for important equipment.
High-temperature-resistant cables: These cables can operate normally in high-temperature environments and are suitable for industries such as metallurgy, chemicals, and glass manufacturing.
Waterproof cables: These cables offer excellent waterproof properties and are suitable for use in humid and rainy environments, such as underwater projects and ships.
Cable Classification Standards and Application Scenarios
Power cables: These cables are primarily used for long-distance power transmission. Common types include VV/VLV and YJV/YJLV, and are suitable for fixed installations such as indoors, in tunnels, and in pipelines.
Control cables: These cables are used in industrial automation and control systems. They feature small-section, multi-core wires and are commonly used for controlling equipment in power stations and substations.
Communication cables and radio frequency cables: These cables are used to build efficient communication systems. Radio frequency cables are particularly suitable for high-frequency signal transmission.
Fiber optic cable: Uses light pulses to transmit information and is suitable for long-distance, high-capacity communications.
Fire-resistant and flame-retardant cables: Maintain power supply in the event of a fire and are suitable for high-rise buildings, subways, and other critical locations.
High-temperature-resistant and waterproof cables: Suitable for high-temperature and humid environments, such as metallurgical, chemical, and marine applications.
