LSZH flame retardant cable XLPE insulation and polyolefin sheath industrial power

Toxic smoke and uncontrolled flame spread from cable fires can cause irreversible damage to commercial and industrial projects worldwide. WDZB-YJY halogen-free low-smoke Class B flame-retardant cable addresses these issues with its dual-core protection design. This cable uses high-quality XLPE insulation and a halogen-free polyolefin sheath, releasing no toxic halide gases during combustion and exhibiting extremely low smoke density (SDR ≤15), facilitating personnel evacuation. Its Class B flame-retardant design effectively prevents flame spread in a 40-minute vertical burning test, while its robust construction can withstand extreme temperatures of -35°C (Northern Europe), 58°C (Middle East), and humid monsoon climates (Southeast Asia). This product has obtained certifications from the EU (CE/RoHS 3.0), North America (UL/cUL), Australia (SAA), and the Middle East and North Africa (SASO), making it an ideal environmentally friendly and safe power solution for global business centers, industrial parks, and infrastructure projects.

WDZB-YJY is a high-performance, low-voltage (0.6/1kV), halogen-free, low-smoke Class B flame-retardant power cable, designed for general-purpose critical power distribution applications in commercial and industrial settings where environmental safety and fire protection are priorities. Its scientifically layered structure ensures stability and safety: it employs two types of high-purity stranded copper conductors (low resistance, high-efficiency power supply), XLPE insulation (anti-aging, high-temperature resistant, low transmission loss), halogen-free low-smoke filler (moisture-proof, environmentally friendly), and a halogen-free polyolefin outer sheath (Class B flame retardant, corrosion-resistant, UV-resistant, scratch-resistant). "WDZB" represents halogen-free (W), low-smoke (DZ), and Class B flame retardant (B)—balancing environmental protection and fire safety; "YJY" indicates the use of XLPE insulation and a halogen-free polyolefin sheath. Its uniqueness lies in its balance of high flame retardancy, environmental friendliness, and cost-effectiveness, avoiding the overuse of fire-resistant cables in non-emergency critical circuits, making it a universal choice for commercial and industrial projects worldwide.

Note: All specifications are in stock (fast shipping within 3 days). Bulk orders can be customized in terms of core count (up to 5+1 cores) and cross-sectional dimensions (1.5~240mm²), and complete environmental and flame-retardant certifications are guaranteed.

WDZB-YJY cables are designed to meet the commercial and industrial power distribution needs of global projects, covering the following application scenarios with high compliance requirements:

• EU Market: Green commercial skyscrapers, non-emergency power lines for data centers, power supply for production lines in industrial parks, power supply for public areas in airport terminals (compliant with CE/RoHS 3.0 standards, meets EN 50200 and LEED green building standards)
• North American Market: Power distribution for industrial manufacturing plants, non-critical power circuits in medical institutions, power supply for lighting and air conditioning in shopping malls, power supply for warehouse logistics centers (UL/cUL certified, compliant with NFPA 70 NEC standards)
• Australia and New Zealand: Coastal commercial complexes, auxiliary power for mining areas, power supply for educational institutions, power supply for public areas in residential communities (SAA certified, resistant to inland high temperatures and coastal salt spray)
• Middle East and North Africa Market: Desert commercial centers, auxiliary non-hazardous areas of oil and gas fields, power supply for smart city public infrastructure, power supply for high-end resorts (SASO certified) (Certified) Certified, heat-resistant and sand-proof
• Global commercial/industrial applications: General power supply for retail chains, food processing plants, water treatment plants, and textile production lines (environmentally friendly and safe, flame-retardant, suitable for general industrial/commercial environments)

What is the difference between WDZB-YJY and WDZBN-YJY?

WDZB-YJY has Class B flame retardancy + halogen-free low-smoke function (prevents flame spread, no toxic fumes); WDZBN-YJY adds fire protection function (maintains power supply during fire). WDZB-YJY is suitable for non-emergency critical circuits, while WDZBN-YJY is suitable for emergency power supply—choose according to whether you need to maintain uninterrupted power supply during a fire.

Can WDZB-YJY be used for outdoor power distribution?

Yes. Its halogen-free polyolefin sheath is resistant to UV rays and moisture. For long-term outdoor use in harsh climates (e.g., Middle Eastern deserts, Southeast Asian monsoon regions), we recommend the enhanced weather-resistant version (WDZB-YJY-W), featuring a reinforced sheath for UV resistance and corrosion protection.

Does it meet Australian SAA and AS/NZS 3013 standards?

Fully compliant. Our WDZB-YJY (SAA certified) version fully complies with AS/NZS 3013 flame retardancy and environmental safety standards. We provide official SAA certification and test reports for all orders to ensure smooth inspection for Australian projects.

What is the minimum bending radius for installation?

For multi-core WDZB-YJY: ≥15 times the cable outer diameter; for single-core (e.g., custom): ≥20 times the cable outer diameter. The flexible type (WDZB-YJYR) has a smaller radius (≥10 * outer diameter) and is suitable for narrow spaces such as machine connections and wall conduits.

Is WDZB-YJY suitable for food processing plants?

Yes. It uses halogen-free, low-smoke materials, does not release harmful substances, and the outer sheath is easy to clean, meeting food industry hygiene standards (ISO 22000). It is widely used in power supplies and auxiliary equipment for food processing plant production lines.

How do you guarantee the quality of bulk orders?

We implement a strict four-step quality control process: raw material inspection (copper, XLPE, sheath material) → flame retardancy testing during production → finished product smoke density testing → pre-shipment certification and verification. All bulk orders come with a complete quality inspection report.
