Medium Voltage XLPE Power Cable (6kV-20kV)

Medium Voltage XLPE Power Cable (6kV-20kV)

Copper core aluminum core XLPE insulated PVC sheathed powerand mainline cables. Copper cross-linked polyethylene power cables are suitable for fixed installations in distribution networks or industrial equipment with rated voltages of 1.8/3kV, 3.6/6kV, 6/10kV, 8.7/15kV, 12/20kV and below.

The Medium Voltage XLPE Power Cable (6kV-20kV range) is engineered for reliable and efficient power transmission in medium-voltage distribution systems. It is widely utilized in industrial substations, utility networks, renewable energy plants, and critical infrastructure power grids.

By utilizing advanced XLPE (cross-linked polyethylene) insulation through a triple-layer extrusion process, this Low Voltage Power Cable ensures excellent dielectric strength, superior thermal stability, and an extended service life under continuous electrical load. We offer both copper and aluminum conductor options, providing flexible cost-performance solutions for diverse engineering requirements.

Conductor: Number of conductors 1 or 3. The conductors shall comply with the requirement given in IEC.

Insulation: XLPE (Cross-linked Polyethylene) according to IEC.

Sheath: PVC (Polyaluminium Chloride) according to IEC.

Metal Screen: Copper Tape Screen.

Characteristics:

Conductor Temperature: Maximum conductor temperature in normal use: 90°C.

Installation Temperature: Ambient temperature under installation shall not be below 0°C.

Minimum Bending Radius: For Three Core Cable: ≥15D. For Single Core Cable: ≥20D. (D = Diameter of cable)

Key Performance Advantages:

- Reliable Medium Voltage Transmission: Designed for stable operation in 6kV-20kV distribution networks, ensuring safe and continuous power delivery.

- Excellent Electrical Insulation: XLPE insulation provides strong resistance to electrical stress and minimizes partial discharge risk.

- High Thermal Resistance: Supports a continuous working temperature of up to 90°C, making it ideal for heavy-load industrial environments.

- Low Energy Loss: Optimized conductor design reduces electrical resistance, improving transmission efficiency over long distances.

Application Scenarios:

- Industrial Power: Distribution networks for manufacturing plants and heavy industry.

- Utility Grids: Urban medium-voltage distribution and substation feeder systems.

- Renewable Energy: Main collection and transmission cables for solar and wind farms.

- Infrastructure: Power supply for transport systems, tunnels, and large-scale public facilities.

- Underground Installations: Optimized for direct burial or duct-based transmission lines.

Built for Reliable Bulk Supply & Engineering Projects:

- Stable Quality for Large-Scale Deployment: Each production batch undergoes strict control to ensure consistent electrical and mechanical performance across long cable runs.

- Compliance with International Standards: Manufactured strictly according to IEC 60502-2, ensuring seamless compatibility with global medium-voltage power systems.

- Flexible Conductor Options: Copper - Higher conductivity and lower energy loss. Aluminum - A cost-effective solution for large-scale utility projects.
