The 6/6–26/35kV XLPE Insulated Power Cable is a medium-voltage (MV) power cable designed for reliable transmission and distribution of electrical energy in utility grids, substations, industrial facilities, and large-scale infrastructure projects. It adopts cross-linked polyethylene (XLPE) insulation, known for its high dielectric strength, low electrical losses, and excellent thermal endurance, ensuring stable performance under continuous load. A typical construction includes a copper or aluminum conductor, conductor screen, XLPE insulation, insulation screen, metallic screen (copper tape or copper wires), and an outer sheath (PVC/PE/LSZH optional). For more demanding installation environments, the cable can be supplied with armoring (STA/SWA) to enhance mechanical protection, making it suitable for use in underground ducts, tunnels, cable trenches, and direct burial systems where long service life and operational safety are essential.
1) Proven Electrical Reliability for the 6/6–26/35kV Voltage Class
Medium-voltage networks require strong insulation integrity and effective electric field control to ensure long-term reliability. This cable is engineered to operate safely across the 6/6–26/35kV range, supported by high-quality XLPE insulation and a complete screening system. The conductor screen and insulation screen help smooth the electric field, while the metallic screen provides additional control and improves safety in MV operation. This design helps reduce electrical stress concentration and lowers the risk of partial discharge—one of the key contributors to MV cable aging. For customers, the benefit is clear: fewer unplanned shutdowns, higher grid stability, and a product that is well suited for critical feeders, industrial power distribution, and substation connections where reliability is non-negotiable.
2) High Thermal Endurance and Efficient Power Transmission Under Heavy Load
XLPE insulation delivers excellent heat resistance and strong thermal aging performance, enabling the cable to maintain stable output under continuous loading conditions. In practical project environments—such as high ambient temperatures, crowded cable routes, or industrial plants with heavy current demand—thermal performance is a major factor affecting service life and safety. XLPE’s low dielectric loss supports efficient power transmission by reducing internal energy loss, helping minimize unnecessary heat build-up over long distances. This translates into improved operational efficiency, better temperature stability, and reduced risk of overheating-related failures, making the cable a strong choice for projects that demand both high performance and long-term cost effectiveness.
3) Durable, Project-Flexible Construction with Options for Harsh Environments
Different projects require different installation methods, safety requirements, and environmental protections. This MV XLPE cable can be supplied in multiple configurations—Cu or Al conductors, single-core or three-core, and various sheath materials such as PVC for general use, PE for enhanced moisture and chemical resistance, or LSZH for applications requiring low smoke and halogen-free performance (e.g., tunnels, metros, public buildings). Optional armoring (STA for multi-core / SWA for single-core) increases resistance to crushing, impact, and external mechanical stress, improving suitability for direct burial and harsh jobsite conditions. This flexibility helps buyers match the cable to local standards and site conditions, optimize total installed cost, and reduce maintenance risk—while still ensuring long service life and reliable MV performance.
