The price of X90 orange circular cable with the same specifications and models is slightly higher than that of V90 orange circular cable, which may be the reason why V90 orange circular cable is still alive. However, the X90 orange circular cable has a longer service life, is more resistant to high temperatures, and is safer. In terms of long-term and safety factors, using YJV cable is more cost-effective.
It is recommended to choose X90 orange circular cable for residential projects, which is safer and more environmentally friendly. If the budget is really limited, you can choose to use V90 orange circular cable in non residential areas and places with low voltage and temperature requirements. In summary, the general trend is that X90 orange circular cables are gradually replacing VV cables.
X-90 orange circular cable is better than V-90 orange circular cable in the long run (with longer service life, etc.), but more expensive than V-90 orange circular cable. From the maximum height allowed for short circuit: X-90 orange circular cable is 250 degrees, V-90 orange circular cable is 160 degrees, 140 degrees.
From the perspective of technical and economic indicators, the X-90 orange circular cable with 3 cores has higher parameters than the V-90 orange circular cable, such as 4c e orange circular, 4mm 2 core and earth orange circular cable, 6mm 2 core and earth orange circular 16mm 4 core and earth orange circular. It is recommended to use X-90 orange circular cable in civil buildings, which has a higher current carrying capacity than VV. More importantly, in the event of an electrical fire, due to its insulation material not containing chlorine, it will not produce toxic gases during combustion. So that means the environmental performance of the V-90 orange circular cable is inferior.
In civil, nuclear and other fields, V-90 orange circular cable has been basically replaced by X-90 orange circular cable. However, in many industrial enterprises, V-90 orange circular cable is still widely used because of its low price. Some people also say that there is not much difference. Simply put, X-90 orange circular cable is used by nobles, while V-90 orange circular cable is used by civilians. The use effect of X-90 orange circular cable is slightly better than V-90 orange circular cable, mainly in terms of insulation. The insulation of X-90 orange circular cable is better than that of V-90 orange circular cable, and its aging resistance is higher. For example, X-90 orange circular cable has been used for 30 years, while V-90 orange circular cable has been used for 28 years, which is the difference.
