Product Overview
YJV22 Cable is a 0.6/1kV XLPE-insulated steel tape armored PVC-sheathed power cable manufactured to China's national standard GB/T 12706.1. Naming per Chinese convention: YJ = XLPE insulation, V = PVC sheath, 22 = double galvanized steel tape armor. YJV22 is the armored counterpart of YJV (unarmored) — both share the same XLPE/PVC construction, with the addition of a helical double steel tape for mechanical protection. It is the most widely specified armored cable in China's domestic construction and industrial markets, and the most commonly exported Chinese-standard armored cable for Belt & Road infrastructure projects.
YJV vs YJV22: Unarmored vs Armored in Chinese Standard
| Designation | Insulation | Armor | Sheath | Use |
