With the development of wire and cable production technology, more wires and cables with different functions are constantly pouring into the market. There are many types of cables, but the most basic can be divided into low-voltage cables and high-voltage cables. How should the two be distinguished? What?
First, you can look at the structure. There are many layers of high-voltage cables, and there are armor, shielding layers, insulating layers, conductors, etc. inside the stripped outermost layer. Low-voltage cables generally pull out the outermost layer, and the inside is the insulation layer or wire.
Second, the high-voltage cable insulation layer is relatively thick, and the low-voltage cable insulation layer is relatively thin. The insulation layer of low-voltage cables is generally within 3 mm, and the insulation layer of high-voltage cables is generally above 5 mm.
Third, you can see the nameplate on the outermost layer of the cable. Generally, the relevant parameters of the cable are printed on the outermost layer of the cable, including the cable model, cross-sectional area, rated voltage, length and other parameters.
Low voltage cable: low voltage 0.6kV copper core XLPE insulated PVC sheathed steel tape armored three-core 70 square cable (YJV22-0.6/1kV-3*70)
The structure of low-voltage cables is different from that of high-voltage cables with conductor shielding layer, insulating shielding layer, and metal shielding layer. The difference is mainly due to the difference in insulation capacity of different voltage levels. The electric field capacity of low voltage 0.4KV is much weaker than that of 10KV. Air penetration or insulation breakdown.
Three, the difference in usage:
High-voltage cables can only be used after the cable heads are made according to a strict manufacturing process, while low-voltage cables are not mandatory to make cable heads. The laying requirements of high-voltage cables and low-voltage cables are also different.
