What is the difference between YJV and YJV22?
YJV refers to copper core polyethylene insulated polyvinyl chloride sheathed power cables, which are usually laid indoors, in tunnels, and pipelines. The cables cannot withstand pressure and mechanical external forces.
YJV22 refers to copper core polyethylene insulated steel strip armored polyvinyl chloride sheathed power cables. There are usually two types of cable armor layers, steel strip armor and steel wire armor. To put it more simply, armored cables are buried wires and cables that transmit electrical energy through power lines. The purpose of adding an armor layer to the cable is not only to enhance mechanical protection such as tensile strength and compressive strength, but also to extend its service life. Armor also has resistance to external forces and can prevent some mice from biting, so as not to cause power transmission problems through the armor. The bending radius of the armor should be large, and the armor layer can be grounded to protect the cable.
YJV22 cables are usually laid indoors, in tunnels, and directly buried in soil, and can withstand pressure and other external forces. In order to protect the integrity and electrical performance of the cable structure, and improve the service life of the cable, it is necessary to add an armor layer to the outer protective layer of the cable.
