Single Core 19/33KV Medium Voltage Aluminum Wire Armoured Cable

The Single Core 19/33kV Medium Voltage Aluminum Wire Armoured Cable is designed for high-voltage power transmission applications. It features an aluminum conductor with a cross-sectional size suitable for 19/33kV systems, insulated with XLPE for excellent electrical properties and thermal performance. The cable is equipped with steel tape or wire armour to provide mechanical protection and a durable outer sheath for environmental resistance. This cable is ideal for underground and outdoor power distribution networks in industrial, commercial, and infrastructure projects, ensuring safety, reliability, and long-term performance.
