YJV and YJY are both models of power cables, and there are some differences in their structure and performance.
First of all, the structure of the YJV cable includes a conductor, an insulating layer, a filler layer, a metal shielding layer and an outer sheath from the inside out. The conductor is made of multi-strand copper wire, which has good electrical conductivity. The insulation layer is made of cross-linked polyethylene material, which has good electrical properties and heat resistance. The filler layer is located between the conductor and the metal shield, which reduces the stress of the cable when it bends. The metal shield is made of fine copper wire, which can effectively prevent electromagnetic interference and external mechanical damage. The outer sheath is made of polyvinyl chloride material, which is corrosion-resistant and waterproof.
In contrast, the structure of YJY cable is different. It also includes conductors, insulation, filler and outer sheath, but the metal shield is wrapped with copper tape. This structure provides better protection against electromagnetic interference and external mechanical damage.
In addition to the structural differences, YJV and YJY cables are also different in performance. YJV cable has high electrical performance and heat resistance, and is suitable for harsh environments such as high temperature, high humidity and high pollution with rated voltage of 6KV to 35KV. The YJY cable has a better ability to prevent electromagnetic interference and external mechanical damage, and is suitable for occasions that require higher protection requirements.
In practical applications, the choice of which type of cable should be decided according to the specific use environment and requirements. If you need higher electrical performance and heat resistance, you can choose YJV cable; If you need better protection against electromagnetic interference and external mechanical damage, you can choose YJY cables.
In short, there are some differences in structure and performance between YJV and YJY cables, which need to be selected according to the specific use environment and requirements.
