For the first time buying wires, the decision to choose single, double, or multi-core wires seems simple but confusing. Understanding the characteristics and uses of each type of wire will make it easier for customers to understand and shop as well as avoid confusion between the products.
Characteristics of multi-core power cables
One of the criteria for classifying electric cables depends on the number of cores of wires. The single-core type of wire is called a single wire or single cable. Products with multiple cores will be named according to the actual number of cores in the wire such as 2-core wires (also called double wires), 3-core wires, etc. The number of cores in the conductor usually ranges from 2 to 5 cores. In addition, major cable manufacturers such as Tran Phu Electric Engineering can also produce wires with more special requirements on the number of cores required by customers.
Wires with double cores and multiple cores are commonly used
People usually think that any kind of wire or cable is able to conduct electricity the same. This is not entirely true. Multi-core cables can conduct more electricity and heat well, and carry different currents than single-core wires. However, the more cores the cable has, the higher the specifications are required.
The reason why multicore power cables should be used
Compared to single-core cables, multi-core power cables are used more for a number of reasons:
Dây cáp điện nhiều lõi dễ tuốt và dễ dàng đấu nối
During the course of using electricity, there will be times when we need to connect the electrical wires together for an intention in the use and handling of electrical equipment. When we remove the outer shell, it can be seen that the inside core is a lot of thin material wires twisted together. Multi-core wires are more easily plucked off with soft-core strands. In contrast, single-core wires will be difficult to pluck as they are much harder.

Good electrical conductivity and conduction of many currents
Most people often think that all types of electrical cables have the purpose of conducting electricity; small wires are used for small projects, while large wires are used for conducting electricity for large projects. That's why during the purchase, buyers rarely care about the number of cores inside, but only interested in which one is of good quality. However, sing-core or multi-core power cables have their own special advantages and uses.
Multi-core wires are usually softer, more malleable, as well as have better conductivity, and lead more current. This is the reason why multicore power cables are preferred and used more because they are not only effective but they also help reduce the investment costs of starting materials.
Identify double wires and multiple cores
On the packaging, information on the number of cores will be recorded along with the cross-section, following the symbol of voltage level, core material, insulating material.
For example, 0.6 / 1kV Cu / XLPE / PVC 3Cx50 + 1Cx25mm
Thus, the above wire is a 4-core wire including 3 phase core with a cross-section of 50mm2 and 1 neutral core with a cross-section of 25mm2.
The choice of wires in general, whether single or multiple cores, must be based on the intended use of each specific use case. Currently, Tran Phu Electric Mechanical Joint Stock Company is a reputable manufacturer and supplier of 2-3-4 core wires, with diverse specifications.
