The 6/6–26/35kV XLPE Insulated Power Cable is a medium-voltage (MV) power cable designed for reliable energy transmission and distribution in utility networks, substations, industrial plants, and large-scale infrastructure projects. It features cross-linked polyethylene (XLPE) insulation, which offers high dielectric strength, low electrical losses, and excellent thermal endurance, ensuring stable performance under continuous load conditions. A typical MV XLPE cable structure 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 installations such as tunnels, direct burial, and harsh jobsite environments, the cable can be supplied with armoring (STA/SWA) to provide enhanced mechanical protection. With strong electrical stability and durable construction, this MV XLPE cable is widely used in power distribution systems, renewable energy projects, and industrial power supply lines where long service life and operational safety are essential.
1) Enhanced Electrical Stability and Long-Term Reliability in MV Applications
Medium-voltage systems place high demands on insulation integrity and electric field control. This cable is engineered for the 6/6–26/35kV voltage range with a complete insulation and screening structure designed to support stable MV performance over time. The XLPE insulation provides strong dielectric strength and stable electrical characteristics, while the conductor and insulation screens help smooth the electric field, reducing stress concentration points that can accelerate insulation aging. The metallic screen adds an additional safety layer by supporting controlled shielding and improving fault management capability. Together, these features help reduce the risk of partial discharge and insulation deterioration, which are major causes of MV cable failure—delivering higher service reliability, lower maintenance frequency, and improved network stability for utilities and industrial users.
2) High Thermal Endurance with Low Loss for Efficient Power Transmission
XLPE insulation is well known for its superior heat resistance and strong thermal aging performance, making it suitable for circuits that operate under continuous load or experience peak-demand conditions. In practical installations such as ducts, tunnels, or densely packed cable routes where heat dissipation can be limited, thermal stability directly affects service life and operational safety. XLPE also provides relatively low dielectric loss, helping reduce internal energy loss and unwanted heat generation during transmission. These advantages support stable current-carrying performance and improved energy efficiency—particularly valuable for long-distance distribution lines, renewable energy collection systems, and industrial feeders where consistent performance and reduced overheating risk translate into real operational savings.
3) Durable Construction and Configurable Options to Match Different Project Requirements
This MV XLPE cable can be tailored to diverse installation environments and regulatory requirements. Customers can choose Cu or Al conductors, single-core or three-core designs, and sheath materials such as PVC for general applications, PE for enhanced moisture and chemical resistance, or LSZH for low-smoke, halogen-free performance in public areas or enclosed spaces. Optional armoring (STA for multi-core / SWA for single-core) further improves resistance to impact, crushing, and external mechanical stress, making the cable well suited for direct burial or rugged job sites. This flexibility allows contractors and utilities to optimize for installation method, safety level, and total project cost—while still maintaining a robust design focused on long service life, mechanical durability, and dependable medium-voltage performance.
