What are the differences between wires and cable
There are many details to pay attention to when selecting wires and cables, and it is necessary to distinguish them clearly in advance to ensure their later use. What are the differences between wires and cables.
1. The two have different structures, and the wire chosen for the wire is basically a combination of several relatively soft wires with an insulation layer on the outside. The cable is composed of one or several bare wires, with an outer layer made of rubber.
2. Different sizes, small wire sizes, complex structures, and larger cable sizes.
3. Due to different functions, wires can carry relatively less electricity. Choose cables, which have strong load-bearing capacity and are usually used to transmit large amounts of power, current, etc.
4. The hardness is also different. When choosing wires, the hardness is not as high as that of cables, and they are relatively soft because their power and current carrying capacity are not very good.
What to pay attention to when selecting wires
1. Load capacity
The electricity consumption of a household is constantly changing. If the electricity consumption is high, TV, air conditioning, computer, desk lamp, water purifier, refrigerator, hair dryer, etc. can all be used together. If the load capacity of the wire is not strong, and the weather is hot in summer, the power supply overloaded by the wire may heat up, causing serious consequences such as fire.
2. Waterproofing
Some wires have loose outer packaging and are prone to deformation and cracking. If it ruptures and leaks, it may cause short circuits, short circuits, fires, and personal injury. Therefore, the wire should choose a hard sheath and good waterproof performance.
3. Conductivity
There are copper cores and other wires on the market. Copper core wire is the most practical indoor decoration. However, copper core wires can be divided into several types, including large radius copper cores and multi wire copper cores.
4. The main line needs a thick core
The power supply is connected to two main lines from the power supply to all devices. The main line must use thick copper core wire, as it carries the charge of each electrical appliance and requires high-performance thick copper wire.
