YJLV 3×50+2×25 is a 0.6/1kV aluminum core XLPE insulated PVC sheathed 5-core low voltage power cable, manufactured in accordance with GB/T 12706.1 standard. It adopts high-purity stranded aluminum conductor, including 3 main cores with 50mm² cross-sectional area and 2 auxiliary cores with 25mm² cross-sectional area. The insulation layer is XLPE, with a long-term operating temperature of 90℃ and a maximum short-circuit temperature of 250℃. The outer PVC sheath is wear-resistant, moisture-proof, aging-resistant and anti-mechanical damage, with light weight, convenient laying and outstanding cost performance, suitable for medium and high power, long-distance power distribution scenarios. This cable is a standard three-phase five-wire aluminum core cable. The 3 cores of 50mm² are used as phase wires (yellow/green/red), and the 2 cores of 25mm² are used as neutral wire (blue) and protective earth wire (yellow-green bicolor) respectively. The core specification matching is scientific, with large ampacity, stable insulation performance and high safety. It is widely used in high-power equipment power supply of industrial plants, main power distribution lines of buildings, main municipal engineering wiring, outdoor long-distance power transmission, power distribution of large-scale building groups and other scenarios. It is suitable for indoor and outdoor fixed installation, conduit embedding and overhead laying, and is the preferred cost-effective aluminum core cable for medium and high power low-voltage power distribution.
