Productbeschrijving
WDZA-YJY 0.6/1kV is a Class A low-smoke halogen-free flame-retardant low-voltage power cable conforming to GB and IEC LSZH standards.
Model Description: WDZA = Low-smoke halogen-free + Class A high-grade flame retardant; YJY = XLPE insulation + LSZH outer sheath. All insulation and sheathing are made of halogen-free environmentally friendly polymer materials, without added halogen raw materials.
Structure: High-purity dense copper conductor + XLPE insulation layer + environmentally friendly halogen-free filler + low-smoke halogen-free outer sheath, no flame-retardant inorganic coating layer, no metal armor.
Market Positioning: Suitable for mandatory wiring in confined spaces, large public buildings, and high-standard new energy projects with strict requirements for smoke and toxic gas control; mainstream bidding cables for airports, subways, integrated pipe corridors, high-end hospitals, and landmark commercial complexes; widely exported to high-standard infrastructure procurement markets in Europe, Southeast Asia, and the Middle East.
Raw Materials: ≥99.97% electrolytic copper, conforming to IEC60228 standard; Two options: Category 1 solid round copper, Category 2 tightly stranded copper
Core Wire Combination: 1C/2C/3C/4C/5C/3+1C/3+2C seven-core structure
Cross-section Range: Standard stock: 1.5mm²～300mm²; Extra-large custom specifications: 400～630mm², suitable for special high-current projects
Quality Control: The DC resistance of the finished conductor is strictly lower than the standard upper limit to suppress long-term circuit power loss.
XLPE Insulation: Long-term allowable operating temperature 90℃, short-circuit instantaneous withstand temperature up to 250℃, low thermal deformation, maintaining stable insulation performance even under high-density bundled heat accumulation.
Inner Filler: Halogen-free, low-smoke, environmentally friendly filler material, low water absorption, maintains cable roundness under open flame and does not release toxic fumes.
Outer Sheath: Special low-smoke, halogen-free modified polyolefin sheath, applicable ambient temperature: -30℃～+70℃, with excellent anti-aging, moisture-proof, and mild chemical corrosion resistance, zero halogen content.
Rated Voltage: U0/U=0.6/1kV
Factory Power Frequency Withstand Test: 3.5kV/5 minutes without breakdown
Fire Resistance: Class A flame retardant + low-smoke, halogen-free characteristics; smoke density and toxicity index meet national authoritative testing standards for low-smoke, halogen-free materials.
When exposed to open flame, it produces only a small amount of light smoke, not dense black smoke; ensuring visibility in fire evacuation areas such as enclosed tunnels, underground alleys, and dense cable shafts, significantly improving the safety of personnel escape.
The raw materials do not contain halogen elements such as chlorine and bromine; it does not release toxic or corrosive halogen gases during combustion, avoiding equipment corrosion and personnel poisoning, and meeting high standards of environmental protection and fire protection regulations.
Class A flame retardant performance effectively prevents the vertical spread of flames along the cable trunk line; under conditions of dense multi-row bundled laying, it effectively limits the spread of fire, superior to ordinary ZB/ZC grade flame retardant cables.
XLPE insulation performance is superior to PVC insulated cables, with low dielectric loss, making it suitable for densely stacked cabling in enclosed cable shafts with poor natural heat dissipation.
The entire cable contains no harmful halogens or heavy metal additives, meeting international green building material certification requirements and making it an ideal choice for LEED green building projects.
The unarmored streamlined structure offers moderate bending performance, facilitating pre-embedded conduit installation and high-rise vertical shaft cabling, reducing on-site labor input.
The LSZH sheath incorporates antioxidant and UV-resistant formulations, achieving a nominal design service life exceeding 35 years under standardized installation conditions, reducing subsequent renovation costs for project owners.
Scenario: Public power distribution circuits in subway stations, general power cabling in underground public tunnels, power supply for subway auxiliary equipment; WDZA-YJY cables are mandated by design institutes for enclosed spaces.
Scenario: Public lighting in airport terminals, auxiliary power distribution in waiting halls, conventional power loops in underground passages; LSZH Class A flame-retardant cables are commonly used in large transportation infrastructure.
Scenario: Public power supply for inpatient wards, auxiliary power distribution cabling for medical equipment, fixed laying of underground cable trenches in hospitals; medical buildings have strict regulations for controlling toxic gases in case of fire.
Scenario: Public power trunk lines in super high-rise office buildings, power distribution circuits in shared areas of large shopping malls, fixed cabling within green-certified commercial real estate.
Application Scenarios: Non-emergency auxiliary power circuits for energy storage containers; indoor centralized power distribution wiring for ground-mounted photovoltaic power stations; low-smoke, non-toxic cables are required for enclosed equipment rooms in new energy parks.
Grade Selection Standards: WDZA complete cable set is used for enclosed tunnels, underground pipe corridors, Class A hospitals, and core areas of super high-rise buildings; for open-air ordinary factories, WDZB/YJY can be downgraded to optimize project costs. Our technical team provides free consultation services on matching local fire protection regulations.
Laying Construction Restrictions: Minimum bending radius ≥ 12 times the outer diameter of the finished cable; during cable pulling, prevent sharp pipe ends from scratching the low-smoke, non-toxic cable sheath.
Dense Shaft Laying Tips: When laying in multiple layers of bundles, maintain a fixed heat dissipation gap; the manufacturer provides current carrying capacity data tables for different laying methods for engineers to calculate loads and select cables.
Reasonable Model Division: Strictly distinguish between enclosed, sealed spaces and open, general spaces; configure WDZA-YJY only for enclosed high-fire-risk areas, and select standard YJV for open, non-critical areas to reduce duplicate procurement costs.
Phased Construction and Delivery: Support phased delivery according to project construction progress, reducing on-site warehousing costs and capital tied up for the buyer.
Customized Upgrade Services: For coastal high-salt-spray environments, salt-spray-resistant enhanced LSZH sheaths can be customized before formal ordering.
Domestic Qualifications: CCC mandatory certification, national authoritative third-party LSZH and flame retardant full-type test reports, low smoke toxicity test certificate.
International Compliance: Complies with IEC60332 and IEC61034 international LSZH testing standards, meeting the green building bidding requirements of the EU, Southeast Asia, and the Middle East.
Bidding Assistance: Complete certification materials can be compiled into formal bidding documents, assisting buyers in successfully passing government bidding qualification reviews and overseas high-standard EPC project assessments.
The local EPC contractor procured 82 kilometers of mixed-specification WDZA-YJY series cables, ranging in size from 3×6mm² to 4×185mm², for indoor public power distribution in the terminal building. Local aviation construction strictly adhered to Low Smoke Non-toxic (LSZH) fire safety standards; all products passed third-party on-site smoke density testing. A long-term annual framework cooperation contract was signed after project acceptance.
The municipal rail transit procurement department centrally procured 67 kilometers of WDZA-YJY series multi-core cables for conventional power distribution inside the tunnel. The tunnel environment was enclosed, requiring the cables to have low smoke and non-toxic characteristics. All testing indicators passed the construction quality supervision and acceptance.
A new energy company purchased 43 kilometers of WDZA-YJY cable for the auxiliary power circuit of the energy storage equipment room; low-smoke halogen-free cables were used in the indoor enclosed equipment room, and the entire project was successfully completed and connected to the grid as planned.
