400V 4C 50mm² 4C70mm² 4C95mm² XLPE/CU/PVC Power Cable Summary​ The 400V 4-core power cables, available in 50mm², 70mm², and 95mm², feature a robust XLPE/CU/PVC construction, making them ideal for reliable power transmission in industrial, commercial, and residential settings. The core design combines tinned copper (CU) conductors for excellent conductivity, cross-linked polyethylene (XLPE) insulation for high thermal resistance, and a polyvinyl chloride (PVC) outer sheath for mechanical protection and flame retardancy.​ Rated for 400V, these cables efficiently handle low to medium voltage power distribution, ensuring stable electricity supply for machinery, building complexes, and infrastructure projects. The 4-core configuration supports three-phase power systems, with the fourth core serving as a neutral or earth, enhancing safety and operational flexibility.​ Available in 50mm², 70mm², and 95mm², the cables cater to varying current loads: 50mm² for moderate applications like commercial buildings, 70mm² for industrial machinery, and 95mm² for heavy-duty use in power plants or large-scale facilities. XLPE insulation resists high temperatures (up to 90°C) and chemical corrosion, while the PVC sheath withstands abrasion, moisture, and UV exposure, ensuring durability in harsh environments.​ Compliant with international standards, these cables meet SEO-driven keywords such as "high-performance power cable," "industrial grade wiring," and "flame-retardant 4-core cable," making them a trusted choice for professionals seeking safe, efficient, and long-lasting power solutions.
