What are single-core, two-core, three-core, four-core, and five-core cables suitable for?


Single-core cables are typically used to transmit single-phase AC and DC power, and can also be used in specialized applications (such as high-voltage motor lead-out cables). Generally, medium- and low-voltage, large-cross-sectional area power cables are mostly single-core. Two-core cables are mostly used to transmit single-phase AC or DC power. Three-core cables are primarily used in three-phase AC power grids and are widely used in various small and medium-cross-sectional area cable lines of 35kV and below. Four-core and five-core cables are mostly used in low-voltage distribution lines. Generally, only 0.6/1kV and 1.8/3kV cables have two-core, four-core, and five-core options.
