YJV cable is a common type of cable used in power lines, and its name means cross-linked polyethylene insulated overhead PVC sheathed power cable. It is widely used in power engineering and construction projects. The main features of YJV cable include: the use of cross-linked polyethylene insulation material, which makes the cable's insulation performance more stable, while also improving heat resistance and voltage test capability; the use of PVC sheathing material, which gives the cable better waterproof, acid and alkali resistance, and corrosion resistance; the cable has certain temperature resistance properties and performs well in different environments; through special processing techniques, the cable has strong mechanical properties and tensile strength
