VV22 cable is an armored cable, which has better mechanical properties and stronger resistance to external forces than VV22-4 35 cable. Therefore, VV22 cables are usually used in occasions that need to withstand certain mechanical pressure and external forces, such as high-rise buildings, tunnels, bridges, etc.
The VV22-4 35 cable is a four-core 35 square millimeter PVC insulated PVC sheathed power cable, which is mainly used for low-voltage power lines, such as power supply lines in residential quarters, commercial buildings, factories and other places. Compared with VV22 cable, VV22-4 35 cable is more affordable, so it is also often used in some more sensitive occasions.
In addition to the above two types of cables, there are many other cable types and specifications, such as YJV, ZR-KVV, etc. Each cable has its own unique characteristics and applications, so when choosing a cable, you need to choose according to the actual situation.
When choosing a cable, you need to consider its voltage level, conductor material, insulation material and other factors. At the same time, it is also necessary to consider the installation environment, laying method, use temperature and other factors of the cable. Only by taking these factors into account can we select the right cable and ensure that it is safe and reliable during use.
In conclusion, VV22 cable and VV22-4 35 cable are two different types of cables, each of which has its own unique characteristics and application occasions. When choosing a cable, you need to choose it according to the actual situation to ensure that it is safe and reliable during use.
