Rated voltage 6/6-26/35KV cross-linked polyethylene insulated power cable

The 6/6–26/35kV XLPE Insulated Power Cable is a medium-voltage (MV) cable engineered for secure and efficient power transmission and distribution in utility grids, substations, industrial facilities, and major infrastructure projects. It uses cross-linked polyethylene (XLPE) insulation, delivering high dielectric strength, excellent thermal endurance, and strong resistance to electrical aging. A standard MV cable design typically 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 installations that require additional mechanical protection—such as direct burial, tunnels, and harsh jobsite conditions—the cable can be manufactured with armoring (STA/SWA) to improve impact and crush resistance. With balanced electrical performance and durable construction, this cable is widely used in power distribution networks, renewable energy collection systems, and industrial power supply lines where long service life and operational reliability are essential.

1) Strong Insulation System for Stable MV Operation and Higher Safety

This cable is designed specifically for the 6/6–26/35kV class, where insulation performance and electric field control are the most critical factors affecting service life. XLPE insulation provides high dielectric strength and stable insulation characteristics over time, helping the cable withstand the electrical stress typical of medium-voltage networks. The conductor screen and insulation screen help create a smoother electric field distribution, while the metallic screen further improves safety by providing controlled shielding and helping manage fault currents. This complete insulation and screening structure supports reduced risk of partial discharge and insulation deterioration, contributing to improved long-term reliability—especially important for substations, industrial feeders, and distribution lines where downtime, repairs, and replacement are costly.

2) High Thermal Endurance with Low Loss for Efficient Power Delivery

XLPE insulation offers excellent heat resistance and strong thermal aging performance, allowing the cable to operate reliably under continuous load and in challenging thermal environments. In real installations, cables may be placed in ducts, tunnels, or crowded trenches where heat dissipation is limited; thermal stability becomes essential to maintaining safe operation and preventing accelerated aging. XLPE also features relatively low dielectric loss, which helps reduce internal energy loss and unnecessary heat build-up during transmission—an advantage for long-distance routes or high-load circuits. For end users, these benefits translate into more stable current-carrying performance, improved efficiency, and reduced risk of overheating-related failures over the cable’s working life.

3) Durable Construction and Flexible Configurations to Match Project Requirements

Different markets and projects require different structures, materials, and safety standards. This MV XLPE cable can be supplied with copper or aluminum conductors, in single-core or three-core constructions, and with sheath options such as PVC for general applications, PE for improved moisture and chemical resistance, or LSZH for projects requiring low-smoke and halogen-free performance in enclosed or public spaces. Optional armoring (STA for multi-core / SWA for single-core) increases resistance to crushing, impact, and external mechanical stress, making the cable more suitable for direct burial or jobsite environments with higher mechanical risk. This flexibility helps customers choose the most cost-effective and compliant solution for their installation method, site conditions, and local standards—while maintaining durability, safety, and long service life.
