Common types of multi‑core cables include 2‑core, 3‑core, 4‑core, 5‑core, 3+1‑core, 3+2‑core, 4+1‑core, and more; the number of cores in control cables can reach as high as 61.
1. What is a Multi-Core Cable?
A multi-core cable refers to a cable that has more than one insulated conductor.
Common types of multi-core cables include 2‑core, 3‑core, 4‑core, 5‑core, 3+1‑core, 3+2‑core, and 4+1‑core cables; the number of cores in control cables can reach up to 61.
Two wires are used to control an electrical appliance: one is the live wire, and the other is the neutral wire. The switch is connected in series along the live wire to turn the power on or off.
Three-core cables are typically used for 380V power lines, with one core serving as the neutral wire and the other two as live wires. The connection between the electrical appliance and the power source is controlled by a three‑phase isolating switch or magnetic starter, and they are commonly used for three‑phase motors or electric welders.
Four-core cables are typically used for service entrance power lines: one core connects to the neutral wire, while the other three cores are connected to the A, B, and C phase wires of the transformer. The load on each of the A, B, and C phase wires is roughly equal at the end, ensuring stable output power from the transformer.
The five‑core cable is typically used in spaces that are not very large and have numerous electrical appliances. It allows you to control five appliances, with the multi‑way switch connected in series along each of the five live wires, while all five appliances share a single neutral wire.
2. Advantages of Multi-Core Cables A multi-core cable refers to a cable that contains more than one insulated conductor, which reduces the skin effect and thereby lowers line losses.
