Composé isolant XLPE pour câbles moyenne tension

XLPE Insulation Compound (crosslinkable polyethylene insulation compound) is a premium-grade, high-performance insulation material specifically developed for medium-voltage (MV) power cables rated up to 35 kV. Manufactured from high-purity polyethylene resin, dicumyl peroxide crosslinking agent, and advanced antioxidant additives through a precision closed-system plasticizing granulation process, this compound delivers exceptional electrical, thermal, and mechanical properties essential for reliable long-term cable performance.

Key Features and Benefits

• Outstanding Electrical Performance: Extremely low dielectric dissipation factor and high volume resistivity ensure minimal power loss and superior insulation integrity.
• Excellent Mechanical Strength: High tensile strength (22.5 MPa) and elongation at break (540%), with minimal variation after accelerated aging.
• Superior Thermal Stability: Rated for continuous operation at 90°C, with excellent hot set performance and low impurity content for reduced risk of defects.
• Clean and Consistent Quality: Produced using Loss-in-weight Feeder technology in a closed system, guaranteeing stable formulation and minimal contamination.
• High Crosslinking Efficiency: Achieves 86% gel content for robust long-term thermal and mechanical endurance.

This XLPE insulation compound is ideal for both single-core and multi-core MV cables used in underground, overhead, and industrial power distribution systems.

Recommended Processing Conditions

The compound is designed for conventional single-screw or three-layer co-extrusion lines (L/D ratio 20:1 to 30:1). Suggested temperature profile:

• Feeding Section: 90–100°C
• Compression Section: 100–110°C
• Homogenization Section: 105–115°C
• Model Section: 110–120°C

Actual parameters should be optimized according to equipment and line speed.

Packaging and Storage

• Packaging: 500 kg per package in corrugated cartons with tray base and inner sealed plastic film bag for maximum protection.
• Storage: Store at room temperature in a clean, dry, and well-ventilated area. For best performance, use within six months from the date of manufacture.

XLPE Insulation Compound for MV Cable Up To 35kV offers cable manufacturers a reliable, high-quality solution that meets stringent international standards for medium-voltage power cable insulation.
