Single Core 19/33KV Medium Voltage Unarmoured Cable

The Single Core 19/33kV Medium Voltage Unarmored Cable is designed for high-performance electrical power transmission at medium voltage levels. It features a single conductor, typically made of copper or aluminum, insulated with high-quality XLPE (cross-linked polyethylene) to ensure excellent dielectric strength, thermal stability, and environmental resistance. The unarmored construction provides flexibility, ease of installation, and cost-effective deployment, making it suitable for indoor, outdoor, and underground applications where mechanical protection is not a primary concern. This cable is ideal for industrial facilities, urban power distribution, and infrastructure projects requiring reliable, efficient, and safe medium voltage electrical connectivity.
