Stranded Conductor

XLPE Insulation

Cross-Linked Structure

Protective Outer Sheath

YJV is the abbreviation for "copper conductor XLPE-insulated PVC-sheathed power cable", manufactured to GB/T 12706 series, with rated voltages of 0.6/1 kV, 8.7/15 kV and 26/35 kV. It is the dominant MV/LV power cable in urban grids, building distribution and industrial power supply. "YJ" stands for cross-linked polyethylene (XLPE) insulation; "V" for PVC sheath. Compared with traditional VV (PVC-insulated) cable, YJV allows 90 ℃ continuous operation, offers higher ampacity and longer service life.

Find answers to common questions about YJV power cables, including specifications, applications, installation, and customization.

YJV is one of the most widely used MV/LV power cables in China's distribution network. "Y" = polyethylene insulation, "J" = cross-linked (XLPE), the second "V" = PVC sheath. Because cross-linking raises XLPE to 90 ℃, YJV offers ~30% higher ampacity than traditional VV, with excellent electrical, mechanical and chemical-resistance properties. It is used in 0.6/1 kV to 35 kV transmission and distribution systems — the "vascular network" of urban grids, high-rises, industrial plants and renewable energy farms.
