The primary applications of electrical wires and cables include the following:
Electrical Power Transmission:
Power cables: Used in power systems to transmit high currents (e.g., plastic-insulated power cables, oil-paper insulated power cables).
Overhead lines: Exposed conductors used for long-distance, high-capacity power transmission.
Signal Transmission:
Communication cables: Used for transmitting information such as telephone, television, and data signals (e.g., coaxial cables, local telephone cables, data cables).
RF (Radio Frequency) cables: Used for transmitting high-frequency signals, such as radio and microwave signals.
Electromagnetic Conversion:
Enamelled wire: Primarily used for windings in motors, transformers, and electrical appliances to facilitate the mutual conversion between electrical and magnetic energy.
Specific System Applications:
Power systems: Utilize overhead bare conductors, busbars, branch cables, etc., to ensure a stable power supply.
Information transmission systems: Utilize fiber-optic cables, television cables, etc., to achieve high-speed, high-quality information transmission.
Mechanical equipment and instrumentation systems: Primarily utilize power cables, data cables, instrumentation cables, etc., to ensure proper equipment operation and data acquisition.
