BV wire is a common wire material that is widely used in domestic, commercial and industrial fields. Identifying the voltage level of a BV wire is essential for electrician installation and maintenance. This article will introduce some quick ways to identify the voltage level of BV wire to help readers better understand and use this wire.


1. Observe the cable label

BV wires are usually printed with a logo on the outer skin, which contains the voltage level of the wire. Common voltage level marks are 220V, 450V, 750V and so on. By carefully observing the mark on the surface of the wire, you can quickly understand the voltage level of the wire.

2. Check the cross-sectional area of the cable
The cross-sectional area of the BV wire is related to the voltage level of the wire. In general, the larger the cross-sectional area, the higher the voltage level of the wire. You can initially determine the voltage level by measuring the cross-sectional area of the wire. In general, the cross-sectional area of the BV wire is between 0.5mm² and 10mm².

3. Reference wire color
In China, the color of the BV wire is also related to its voltage level. Generally speaking, the color of BV wire is red, yellow, blue, black, green, and so on. Among them, red represents the 220V voltage level, yellow represents the 450V voltage level, blue represents the 750V voltage level, black represents the 1000V voltage level, and green represents the 1500V voltage level. By referring to the color of the wire, you can get a preliminary idea of the voltage level of the wire.

4. Ask technical personnel to check
If you still have questions about the voltage level of the wire, or need a more accurate judgment, it is recommended to ask technical personnel to check. An electrician or wire supplier can identify the voltage level of a BV wire with specialized equipment and experience.

In SUMMARY:
Identifying the voltage level of a BV wire is essential for electrician installation and maintenance. You can quickly and accurately determine the voltage level of the BV wire by observing the wire identification, checking the wire cross-sectional area, referring to the wire color, and asking the technical personnel to check. When using BV wires, make sure you choose the right wire based on its voltage level to ensure a safe and reliable power supply.
