A Minute To Take You To Understand The Difference between VV22 And YJV22

Difference one: the power cable outer skin packaging is different

W: is polyvinyl chloride insulated PVC sheathed power cable;

W22: is polyvinyl chloride insulated PVC sheathed steel belt armored power cable;

YJV: is cross-linked polyethylene insulated PVC sheathed power cable;

YJV22: is cross-linked polyethylene insulation polyvinyl chloride sheathed steel belt armored power cable.

Difference two: the power cable application range is different

VV22: laid indoors, tunnels and directly buried in the soil, the cable can withstand pressure and other external forces.

YJV22: suitable for fire resistance requirements when buried, not suitable for laying in the pipeline.

Extended information: The model number of wire and cable for electrical equipment and power cable consists of the following seven parts:

1. category

2. Use code.

3. Conductor code.

4. Insulation layer code.

5. Sheath code.

6. Feature code.

7. Armor layer code.

8. Outer sheath code.

Oil-filled power cable model consists of product series code and cable structure parts code; self-capacitating oil-filled cable product series code CY; outer sheath structure from inside to outside with the strengthening layer; armored layer; outer layer code combination; insulation type; conductor material; inner sheath code and the order of arrangement of the code and the product expression method is the same as 35kV and below power cable.
