What is WDZ-BYJ cable? (Core knowledge, completely original)

WDZ-BYJ is a high-quality low-voltage (0.45/0.75kV) single-core halogen-free, low-smoke, flame-retardant building wire, specifically designed for terminal power distribution (lighting, sockets, low-power appliances) in residential and commercial buildings. Its optimized single-core structure ensures reliability and ease of use: 1/2-grade high-purity solid/stranded copper conductor (low resistance, stable power supply), halogen-free low-smoke XLPE insulation (environmentally friendly, fire-resistant, anti-aging, and high-temperature resistant core wire), and no outer sheath (streamlined design for easy conduit installation). "WDZ" stands for Halogen-Free (W), Low Smoke (DZ), and Flame Retardant—the gold standard for environmentally friendly and safe indoor wiring; "BYJ" stands for XLPE insulated building wire (single core, for terminal wiring). Its unique feature is that it combines the environmental safety of halogen-free materials with the practicality of single-core wiring, eliminating fire and environmental risks in indoor spaces, making it the preferred choice for modern green buildings.

Core Selling Points (SEO & GEO Optimization, New Content)

• Halogen-Free and Low Smoke Indoor Safety:

  Compliant with RoHS 3.0 and REACH standards, free of 10 hazardous substances. It does not produce toxic halogenated gases during combustion, and the smoke density (SDR≤12) ensures clear visibility at the scene of a fire—crucial for enclosed indoor spaces such as bedrooms, offices, and shopping malls, and easily passes global environmental testing.

• Flame Retardant, Preventing Fire Spread:

  Compliant with IEC 60332-1-2 and UL 1685 flame retardant standards (B/C level), it does not spread or drip flames when burning vertically. Preventing the spread of fire along electrical wires and protecting buildings and lives is a mandatory requirement in global residential and commercial building codes.

• Single-core flexible design for easy wiring:

  Available with solid/stranded copper conductors (solid conductors for long-distance straight wiring, stranded conductors for frequent bending). Minimum bending radius ≥ 6 times the cable diameter, easily passing through conduits, wall pipes, and ceiling cavities—saving up to 35% on wiring labor costs compared to rigid multi-core wires.

• All-weather durability (-30°C to 90°C):

  Halogen-free XLPE insulation with added antifreeze, UV resistance, and moisture-proofing agents. Resists the harsh winters of Northern Europe, the dry heat of the Middle East, the humid monsoons of Southeast Asia, and coastal Australia—suitable for all indoor/outdoor terminal wiring scenarios worldwide.

• Global multi-certification and cost savings:

  CE/RoHS 3.0 (EU), UL/cUL (North America 600V), SAA (Australia/New Zealand), SASO (Middle East and North Africa), and IEC 60228 (global). A single cable can meet the needs of multiple residential and commercial markets, avoiding the costs of duplicate certifications. The sheathless design reduces material costs by 15%, while the easy installation method significantly reduces labor costs.

Frequently Asked Questions (Hotly asked questions by overseas buyers, 100% brand new)

• What is the difference between WDZ-BYJ and BV cables?

  WDZ-BYJ is a halogen-free, low-smoke, flame-retardant cable with XLPE insulation (operating temperature 90℃); BV is a PVC-insulated cable (operating temperature 70℃) and does not have halogen-free, low-smoke characteristics. WDZ-BYJ is more environmentally friendly and suitable for indoor use, while BV is a general-purpose cable. WDZ-BYJ is a mandatory cable for green buildings, while BV is suitable for foundation engineering.

• Can WDZ-BYJ be used for outdoor terminal wiring?

  Yes. Its halogen-free XLPE insulation layer has UV resistance and moisture resistance. For long-term outdoor use (e.g., garden lighting), we recommend installing protective conduits; our WDZ-BYJ-W weather-resistant cable (with UV-resistant insulation) is also suitable for direct outdoor use.

• Does it comply with the latest EU RoHS 3.0 indoor air quality standard?

  Fully compliant. All WDZ-BYJ cables fully comply with RoHS 3.0 (2015/863/EU) and EN 50575 indoor air quality standards, and do not release volatile organic compounds (VOCs). We provide official test reports for bulk orders to ensure compliance with EU market access requirements.

• What is the difference between solid and stranded conductors in WDZ-BYJ?

  Solid conductors (Category 1) are suitable for long-distance straight wiring (e.g., ceiling lighting wiring); stranded conductors (Category 2) are more flexible and suitable for frequent bending (e.g., socket wiring in narrow wall conduits). Both have the same fire resistance – please choose according to your wiring needs.

• Is WDZ-BYJ suitable for high-density residential buildings?

  Yes. Its flame-retardant and halogen-free properties make it ideal for high-density residential buildings (apartments, apartment buildings). It effectively prevents the spread of fire between units, avoids the accumulation of toxic fumes in public corridors, and complies with global high-density building fire safety codes.

• What is the lead time for bulk orders?

  The lead time for standard bulk orders (in-stock specifications) is 5-10 business days; the lead time for customized specifications (cross-section/conductor type) is 12-18 business days. We offer worldwide fast shipping services, including DHL/FedEx/sea freight, and provide door-to-door service.
