Do you know the difference between YJY and YJV?

26-04-2024

YJY and YJV are both common wire and cable products in engineering construction, used for power transmission lines, but what is the difference between them?

YJY - cross-linked polyethylene insulated polyethylene sheathed power cable. The power cable made of polyethylene material has excellent thermomechanical properties, superior flame retardant performance, better carrying capacity than ordinary YJV power cable, and also improves the cable's Electrical performance and heat resistance characteristics. Purpose: It can be laid indoors, in pipes or in loose soil, provided it cannot withstand tension and pressure; it can be used on distribution networks or industrial installations with voltage levels of 1-1000kV and above, such as power stations, urban lighting lines, and high-voltage towers. Power transmission, basement power transmission and other places.

YJY cable has a simple structure, moderate hardness and softness, and is easy to transport, but it is not resistant to compression, so be careful when storing or transporting it.

YJY

YJV cable is also called cross-linked polyethylene insulated PVC sheathed power cable. YJY has better water resistance and low temperature resistance than YJV, while YJV has better flame retardancy than YJY.

YJV

YJV cable has excellent thermomechanical properties, excellent electrical properties and chemical corrosion resistance. It also has the advantages of simple structure, light weight, and no restriction on laying height. It is currently widely used in urban power grids and mines.
