VV difference YJV and power cables first quality control cable, the product name is different, represent different meanings: YJV insulation is XLPE insulation .VV is polyvinyl chloride. Secondly, both in the production equipment and manufacturing process also has the distinction of: VV is plastic power cables, YJV namely XLPE cables, the insulation performance is better than plastic power cables. YJV just on the insulating material made of a crosslinking treatment to improve the heat resistance temperature, and VV did not. YJV cable operating temperature up to 90 degrees control cable monopoly, while only 70 degrees VV control cable, with the cross-sectional area YJV cable carrying capacity. VV type cable conductor running maximum rated temperature of 70 degrees Celsius, when a short circuit (duration less than 5 seconds) the maximum temperature does not exceed 160 degrees Celsius. YJV class conductor running maximum rated temperature of 90 degrees Celsius, when a short circuit (duration less than 5 seconds) the maximum temperature does not exceed 250 degrees Celsius. YJV good in the long run (long life) than VV, but more expensive than the VV. The maximum allowed height from the short look: YJV 250 degrees, VV to 160,140. From the technical and economic indicators cold control cable, three cores are higher than the parameters YJV VV cable. Recommended for use in civil YJV, its carrying capacity larger than VV, more important is the electrical fire, because the insulation material does not contain chlorine, does not produce toxic gases when burned. That is so badly VV's environmental performance. VV has basically been YJV substituted in civilian nuclear power and other fields, but in many industrial enterprises, VV applications is very broad, because it's cheap.
