WDZ-YJY 8.7/15kV LSZH XLPE Insulated Non-Armored MV Power Cable

WDZ-YJY 8.7/15kV is a high-performance, low-smoke, halogen-free medium-voltage power cable designed for high-standard public infrastructure, enclosed spaces, green energy, and high-fire-risk industrial projects worldwide. This cable features high-quality cross-linked polyethylene (XLPE) insulation and a halogen-free thermosetting sheath, combining low-smoke, halogen-free, and flame-retardant properties with a completely non-toxic and environmentally friendly material formulation. Its integrated three-layer co-extruded shielding structure achieves uniform electric field distribution, ultra-low partial discharge suppression, and excellent resistance to water treeing, ensuring stable dielectric performance during continuous operation of a 15kV system.

Unlike traditional PVC-sheathed cables, WDZ-YJY releases virtually no toxic gases, corrosive fumes, or dense smoke during combustion, thereby improving evacuation visibility and reducing equipment corrosion in fire emergencies. Its lightweight, unarmored construction allows for flexible protective installation and fully complies with global environmental regulations, green building standards, and international electrical codes. It is the preferred low-carbon, safety-oriented solution for EPC contractors, facilities engineers, and bulk purchasers, focusing on fire safety, environmental protection, and long-term system stability.

Designed specifically for high-safety, enclosed, and demanding engineering scenarios:

• Urban tunnels, subways, underground utility tunnels, and enclosed municipal facilities
• High-rise buildings, hospitals, schools, shopping malls, and densely populated public buildings
• Data centers, rail transit, airports, and key national infrastructure
• Petrochemical, pharmaceutical, and industrial sites with high requirements for protection against toxic and corrosive gases
• Solar power plants, wind power plants, and green new energy low-carbon supporting power systems
• Indoor cable trenches, enclosed ducts, overhead protective laying, and non-mechanical damage situations

1. Superior Fire Safety and Environmental Performance

   The completely halogen-free formula effectively eliminates toxic and corrosive gases generated during a fire. Low smoke density ensures clear escape visibility, minimizes secondary disaster losses, and protects personnel and precision electrical equipment from chemical corrosion.

2. Stable Medium-Voltage Dielectric Properties

   High-purity cross-linked polyethylene (XLPE) insulation material optimizes electric field balance, effectively suppressing partial discharge and insulation aging, adapting to long-term peak and variable load operation, and reducing the risk of medium-voltage line breakdown and insulation failure.

3. Low Carbon and Environmentally Friendly

   LSZH environmentally friendly materials comply with global low-carbon policies, green building certifications, and EU environmental requirements, helping international projects pass environmental assessments and sustainable building standard certifications.

4. Lightweight design, high construction efficiency

   The unarmored, compact design reduces the overall weight and outer diameter of the cable, simplifying transportation, handling, and conduit routing, shortening the construction cycle, and controlling overall project installation costs.

5. Excellent anti-aging and weather resistance

   The special low-smoke halogen-free sheath has extremely strong heat resistance, moisture resistance, and climate adaptability, resisting long-term temperature fluctuations and the corrosive effects of indoor humid environments, thereby extending its service life.

• Laying Restrictions

  Unarmored structures are only suitable for protected installations; not suitable for direct burial, areas subject to heavy crushing, impact, or rodent infestation. Armored types should be selected for harsh mechanical working environments.

• Material Performance Differences

  WDZ low-smoke halogen-free flame retardant materials prioritize smoke suppression and non-toxicity, not fire resistance. For fire-resistant circuitry, dedicated fire-resistant cables should be used.

• Site Matching Requirements

  Low-smoke halogen-free materials have unique physical properties; engineers must use matching halogen-free accessories, terminals, and sealing materials to ensure the overall fire safety performance of the system.

• Project Code Applicability

  Priority should be given to enclosed spaces and high-density public buildings; compliance with international fire codes and local safety regulations is required to ensure project acceptance.

1. Global Authorized Certifications

   We possess complete CE, RoHS, and third-party fire safety test reports, fully complying with international IEC standards, supporting cross-border customs clearance, EPC bidding, and official acceptance of global projects.

2. Strict Raw Material and Production Control

   We use imported high-performance low-smoke halogen-free compounds and oxygen-free copper conductors. Automated co-extrusion production + 100% partial discharge and high-voltage routine testing ensure consistent batch quality.

3. B2B Customization Support

   We can customize conductor cross-sections, core structures, and special low-smoke flame retardant ratings according to regional project specifications, bidding standards, and individual engineering needs.

4. Factory Direct Sales Cost Advantage

   Direct supply from the manufacturer reduces intermediate costs, providing high cost-effectiveness for large-scale green infrastructure and public facility medium-voltage power projects.

5. Professional Medium-Voltage Technical Services

   We provide professional cable selection guidance, current carrying capacity verification, installation specifications, and after-sales technical support, efficiently solving on-site matching problems for global engineers and procurement teams.
