What are the advantages of single core cables and multi-core cables?
The advantages of single core cable are small cross-sectional area ratio, not easy to air oxidation, short circuit capacity impact resistance, and long service life.
The advantages of single core cable are small cross-sectional area ratio, not easy to air oxidation, short circuit capacity impact resistance, and long service life. The defective wires of single core wires are relatively hard, and it is not convenient to pull wires in some areas, so it is difficult to straighten them after bending, and it is very easy to damage the wires after bending. Advantages of multi-core cable multi-core cable refers to the cable with a copper core cable with an upper insulating layer, which can reduce the skin effect of the cable, thereby reducing the line loss.
The defects of multi-core cable are poor compressive strength, very easy to break, poor surge current resistance, and inconvenient forming. Single core cable or multi-core cable is the best transmission line with the same cross-sectional area. The cost of single copper core cable is more cost-effective than that of multi copper core cable, while the cost of multi copper core cable is slightly higher.
When installing and wiring conduit, the single copper core cable looks a little hard, while the multi copper core cable should be softer and stronger. After installation, single core and multi-core are similar in specific applications.
The difference between multi-core cable and single core cable In terms of circuit capacity, the rated current capacity of single core cable is greater than that of three core cable of the same section; In terms of insulation performance, both single core and three core cables need to comply with national standards. On the premise of meeting the national standards, a certain safety margin is required, which can be understood as qualified insulation performance without distinction;
