Differences between power cables, power cables, and control cables: Power cables, power cables, and control cables differ significantly in their definitions, uses, and characteristics.
Definition and Use:
Power cables: Primarily used for transmitting and distributing high-power electrical energy, they are commonly used in urban underground power grids and power station outbound lines. Their voltage levels are typically 1,000 volts and above, and they have thick insulation. Power cables: They typically have thicker wire diameters, are typically three- or four-core, have thicker insulation between phases, and are protected by metal armor. They are primarily used for three-phase industrial power or single-phase residential power mains in power supply systems. Control cables: Designed for signal transmission, they have thinner wire diameters and are typically shielded. They are suitable for weak current environments and operate at lower voltage levels, generally below 450 volts. Structure and Characteristics:
Power cables: They typically have armored, thicker wire diameters, are suitable for high-voltage environments, and have thicker insulation. 2 Power Cable: These cables have a larger diameter, thicker insulation between phases, and are protected by metal armor. They are suitable for high current transmission.
Control Cable: These cables have a smaller diameter, are typically shielded, and are suitable for low voltage and signal transmission. They also have thinner insulation.
These differences provide a better understanding of the applications and selection of different cables in power systems.
