| How long is the lifespan of a power cord? |
|
The lifespan of a power cord mainly depends on the usage environment, usage habits, and the quality of the materials. It is generally difficult to give a specific time frame, but under normal usage, the lifespan of a power cord can last 3 to 5 years or even longer. Proper usage and maintenance can extend its lifespan, but if the power cord frequently carries a current load exceeding its specifications, it may lead to overheating or insulation damage, shortening its lifespan. If signs of aging, cracking, or exposed wires are found, the power cord should be replaced promptly to ensure safety. |
| What is the difference between wires and cables? |
|
The difference between wires and cables can mainly be distinguished in terms of structure and usage. In terms of structure, a wire typically consists of one or more conductors (such as copper or aluminum wires) and may have an external insulation layer. Its structure is relatively simple, usually consisting of a single conductor. A cable, on the other hand, is made up of a group of conductors, which are wrapped in multiple layers of insulation and protective materials, making its structure more complex. A cable may contain multiple wires, shielding layers, and protective sheaths. In terms of usage, wires are primarily used for single current transmission in homes or industries, typically for simpler applications such as installing sockets, lights, etc. They are more flexible, easy to bend, but are only suitable for light loads. Cables, however, are widely used in more complex scenarios, such as long-distance power transmission, high-voltage power systems, or applications requiring protection from external interference (such as underground power lines, communication lines, etc.). Their structure is more robust, capable of handling large currents and higher pressures, but they are less flexible for bending. |
