PVC XLPE insulated power cable 25mm²
PVC XLPE insulated power cable:
PVC XLPE insulated power cables are suitable for transmission and distribution lines with AC rated voltage Uo / U not exceeding 0.6 / 1kV.
For outdoor and indoor installation in a humid and humid environment, it should be placed directly on the ground where there is excessive mechanical stress in the inclined and moving terrain, in a vertical or inclined place and in a position that is easy to slide.
The main types of power cables YJV22 / YJV32 indicate:
YJ: XLPE insulation
V: PVC insulation
V: PVC sheath
22: Galvanized steel tape armor
32: Galvanized steel wire armor
