Single Core Cable And Multi-core Cable

Single core cable (single core flexible cable 6mm, single core flexible cable 10mm, single core flexible cable 16mm2)Both ends are directly grounded. The metal shielding layer of the cable may also produce circulating currents that can reach the carrying capacity of the cable, and waste electric energy to cause losses.

When the current is not very large, it is better to use single-core cables, such as household cables. Single-core cables have a certain strength, are easier to thread and connect.

Multi-core cable (royal cord multi core rubber cable, electric cooper cable multi core flexible, multicore rvv unshielded cable, gauge It is a cable with multiple mutually insulated conductors in the outer insulation protective layer of the cable.

Multi-core wires are generally three-core wires, because when the cable is running, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the metal shielding layer of the cable. When the current is larger, the cable required is thicker, and multi-core cables are more suitable.

If single-core cables are used, due to the skin effect, current only flows on their surfaces, and a lot of the central part is wasted. The internal current is relatively small, and the cable is not fully used, resulting in reduced utilization. Multi-core cables can effectively reduce the impact of skin effect. From the perspective of utilization, multi-core cables are more suitable.
