WDZ-YJY23 LSZH XLPE STA Armored Power Cable 0.6/1kV for Underground Feeds Product Overview WDZ-YJY23 is a low-voltage copper core power cable designed for fixed installations, meeting two key requirements: Low Smoke Halogen-Free (LSZH) safety, reducing smoke and corrosive halogen gas emissions in fire scenarios; Steel Tape Armor (STA) protection, enhancing the cable's ability to withstand external stresses in underground or mechanically sensitive lines; WDZ-YJY23 is widely

The YJLHV22 is a steel-tape armored low-voltage aluminum alloy power cable designed for harsh laying environments, suitable for applications requiring mechanical protection and direct underground burial. It has a rated voltage of 0.6/1kV and utilizes high-quality AA8000 series aluminum alloy tightly stranded conductors, high-performance XLPE cross-linked polyethylene insulation, a steel tape armor layer, and a weather-resistant PVC outer sheath. As an upgraded armored version

WDZ-YJY23 is a medium-voltage, low-smoke, halogen-free steel-tape armored fixed-lay power cable with a rated voltage of 26/35kV. It employs a composite structure of all-copper conductor + XLPE insulation + double-layer steel tape armor + modified low-smoke, halogen-free inner padding layer + PE outer sheath, specifically developed for underground direct burial, cable trench, and urban integrated pipe gallery medium-voltage trunk power transmission.
