Featuring XLPE insulation and a PE sheath, it's especially suitable for high-fire-risk areas such as high-rise buildings, subways, and industrial plants. Compliant with IEC, CE, and GB standards, it's suitable for projects worldwide from 3.6/6kV to 26/35kV. Enjoy zero toxic smoke, superior heat resistance, and long-term reliability. Flexible minimum order quantities, global shipping, and professional technical support ensure smooth project execution.

• Halogen-Free and Low-Smoke: Does not produce toxic or corrosive fumes when exposed to fire, protecting human health and equipment safety, making it an ideal choice for enclosed spaces such as subways and high-rise buildings.
• Class A Flame Retardant: Effectively prevents the spread of fire, meeting the stringent fire safety standards for critical infrastructure projects.
• XLPE Insulation: Excellent heat resistance (long-term operating temperature up to 90℃), anti-aging properties, and superior electrical insulation performance.
• Global Compliance: Certified by IEC 60502-1, CE, and GB/T 12706, and compliant with local standards in Europe, Southeast Asia, the Middle East, and North America.
• Wide Applications: Suitable for power distribution in industrial plants, commercial buildings, subway systems, hospitals, and data centers.

1. Q1: What does WDZA-YJY in the cable specification represent?

   A1: WDZA = Halogen-Free (W), Low Smoke (D), Class A Flame Retardant (ZA); YJY = Cross-linked Polyethylene (XLPE) Insulation (YJ) + Polyethylene (PE) Sheath (Y). This is a high-safety cable designed specifically for fire-resistant and enclosed environments.

2. Q2: Can WDZA-YJY cables be used in high-temperature environments?

   A2: Yes. The XLPE insulation layer allows for long-term stable operation at 90°C and can withstand short-circuit temperatures up to 250°C (duration ≤5 seconds). Suitable for high-temperature industrial areas and harsh working environments.

3. Q3: What certifications are available in the North American market?

   A3: For the North American market, we offer UL and CSA certifications that comply with NEC standards. This cable meets UL 94 V-0 flame retardant rating and IEEE 1202 smoke density standard, ensuring smooth market entry.

4. Q4: Can the conductor material or length be customized?

   A4: Of course. We offer customization services for conductor materials (copper or aluminum), cross-sectional area (25mm² to 630mm²), length (up to 1000 meters per roll), and flame retardant rating (WDZB/WDZC). Please contact our team for customized solutions.

5. Q5: How to properly store WDZA-YJY cables?

   A5: Store in a dry, well-ventilated warehouse (temperature -5℃ to 40℃, humidity ≤70%). Avoid direct sunlight, rain, and contact with oil/chemicals. Cable reels should be laid horizontally to prevent deformation. With proper storage, the shelf life can reach 8 years.

6. Q6: What after-sales services do you provide?

   A6: We offer a 3-year warranty against manufacturing defects. We also provide free technical consultation, on-site installation guidance, and 24/7 after-sales support. If any quality issues arise, we will promptly provide free replacement or repair services.
