XLPE High Voltage Cable Compound

Description

1. Product Overview
This product is a high-performance cross-linked polyethylene (XLPE) compound engineered specifically for insulation in medium- to high-voltage power cables (up to 500 kV). It is primarily used by cable manufacturers and energy infrastructure projects to produce durable, thermally stable insulation layers. The key value proposition is its superior dielectric strength, long-term heat resistance, and resistance to water-treeing, which directly translates to longer cable life and lower total cost of ownership. Strategically, it is critical as global grid modernization and renewable energy expansion demand reliable, high-capacity transmission infrastructure.

2. Key Specifications & Technical Characteristics

• Chemical composition: Cross-linkable polyethylene base with organic peroxide initiator, anti-oxidants, and proprietary tree-retardant additives

• Purity grade: Ultra-clean grade (< 50 µm maximum foreign particle size, no gels)

• Physical characteristics:

  • Form: Solid cylindrical pellets (3–4 mm diameter)

  • Color: Natural translucent to off-white

  • Density: 0.922–0.928 g/cm³ (at 23°C)

  • Melt flow index (MFI): 2.0–4.0 g/10 min (21.6 kg, 190°C)

• Packaging options: 600 kg aluminum-lined octabins, 25 kg moisture-barrier bags, or bulk pneumatic truck delivery

• Shelf life: 12 months when stored below 30°C in original unopened packaging

3. Core Industrial Applications

• Primary industries: Power cable manufacturing, utility transmission & distribution, offshore wind farm inter-array cables, and underground rail power systems

• Specific use cases:

  • Insulation layer for 66 kV to 500 kV AC/DC extruded cables

  • Insulation for submarine power cables requiring water-blocking performance

• Why better than alternatives:

  • Outperforms paper-insulated lead-covered (PILC) cables with 40% lower dielectric losses

  • More consistent extrusion behavior than standard XLPE – reduces scrap rate by up to 15%

  • Superior tree-retardant formulation extends cable lifespan to 40+ years in wet environments

• Cost advantage: Lower maintenance frequency and higher ampacity reduce lifetime infrastructure cost by ~25% vs. traditional solutions

4. Competitive Advantages

• Quality consistency: SPC-monitored production with 100% inline filtration and dielectric screening – batch-to-batch CV of < 2% for critical properties

• Supply reliability: Dual manufacturing sites (Asia & Europe) with 50,000 MT annual capacity and safety stock held in three regional hubs

• Logistics capability: Just-in-time delivery to cable plants via rail or container – lead time as low as 14 days for repeat orders

• Price competitiveness: Tier-1 performance at 12–18% lower price than established Western European equivalents, without compromising on technical specs

• Sustainability: Manufactured using low-carbon peroxide crosslinking; compound is fully recyclable at cable end-of-life under IEC 60840 standards

• Technical support: Full documentation (CoA, MSDS, extrusion guidelines) plus on-site trial support from polymer engineers

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 metric tons (BULK 20MT) per shipment, combinable across up to two grades

• Loading capacity per container: 24 MT per 20-foot dry container (pallets removed for max density) or 26 MT per 20-foot bulk liner bag container
