1. What is a multi-core cable

A multi-core cable is a cable with more than one insulated core.

Common multi-core cables include two cores, three cores, four cores, five cores, 3+1 cores, 3+2 cores, 4+1 cores, etc. The number of cores of the control cable can reach 61 cores.

Two cores 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 in the middle of the live wire to turn on or off the power supply;

Three-core, generally used for 380V power lines, one of which is the neutral line, and the other two are live lines. The connection between the electrical appliance and the power supply is controlled by a three-way gate switch or a magnetic starter. It is mostly used for three-phase motors or electric welding machines. ;

Four-core, generally used for the power line of the household line, one is connected to the neutral line, and the other three are respectively connected to the A, B, and C live wires of the transformer, and the A, B, and C live wires. All the power consumption at the end is roughly equal, so the output of the transformer smooth power;

Five-core, generally used in a place with a small space, there are many electrical appliances, so that he can control five electrical appliances, the multi-connector switch is connected in series with the five live wires, and the five electrical appliances share a neutral wire.

2. Advantages of multi-core cables Multi-core cables refer to cables with more than one insulated core, which reduces the skin effect of the cable, thereby reducing the loss of the line.
