1.5mm2-400mm2 Low Smoke Zero Halogen Cable WDZB-YJY PVC XLPE EPR Insulation

WDZB-YJY is a low-voltage power cable designed for indoor power distribution projects requiring low-smoke, halogen-free safety and reliable daily power supply. It features copper conductors and cross-linked polyethylene (XLPE) insulation, protected by a low-smoke, halogen-free outer sheath. This construction is commonly used in building cable installations where smoke control and minimizing corrosive gas emissions are critical, such as in risers, shafts, corridors, equipment rooms, and high-density cable trays.

WDZB-YJY is positioned as a compliant low-voltage cable suitable for contractors and EPC purchasers who must meet fire safety requirements while also considering ease of installation and procurement scale.

Supply availability varies depending on the standard and Low Smoke Halogen-Free (LSZH) composite system. Please confirm the specific configuration required for your bid.

• Low Smoke Halogen-Free (LSZH) Sheath, Creating a Cleaner Evacuation Environment
  Low smoke halogen-free composites are widely used to reduce smoke concentration and the generation of corrosive gases, thereby improving visibility and reducing secondary corrosion damage in fires.
• Flame Retardant Properties, Ensuring Cable Safety
  Flame retardant design helps limit the spread of flames along cable paths in shafts, risers, corridors, and cable tray systems.
• XLPE insulation provides stable thermal performance.
  XLPE insulation supports the reliability of low-voltage power distribution under continuous load, helping to maintain stable performance in compact building wiring.
• Suitable for public buildings and compliant projects.
  Commonly used in hospitals, schools, shopping malls, stadiums, stations, and large commercial venues where high fire safety requirements for cables are necessary.
• Facilitates EPC and phased supply procurement.
  Universal configurations and reel designs facilitate bill of materials matching, repeat ordering, and on-time delivery.

• Main low-voltage feeders and branch feeders within buildings.
• Cable trays, risers, shafts, corridors, and equipment rooms.
• Switchboards, switchgear rooms, and service lines.
• Commercial, residential high-rise buildings, and public utilities.
• Industrial buildings meeting Low Smoke Halogen-Free (LSZH) and flame-retardant requirements.

1. Copper conductor production.
   Copper is drawn and stranded into specified conductor grades to ensure stable resistance values ​​and consistent flexibility for easy installation.
2. Cross-linked Polyethylene (XLPE) Insulation Extrusion and Cross-linking
   The insulation layer is extruded and cross-linked to form a robust electrical layer suitable for low-voltage power distribution.
3. Core Identification and Wiring
   Cores are color-coded or numbered and stranded in specified quantities, using fillers and binding tape to maintain a stable geometry.
4. Low Smoke Halogen-Free (LSZH) Compounding and Sheath Extrusion
   Low smoke halogen-free sheath systems are extruded to provide line protection and meet flame retardant and smoke performance requirements.
5. Routine Testing and Inspection
   Typical inspection items include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional verification, and sheath integrity checks. Documentation is available upon request.

• Conductor: Copper
• Insulation: Cross-linked polyethylene (XLPE)
• Outer sheath: Low smoke halogen-free (LSZH) composite flame-retardant system (Class B mentioned in many specifications, depending on the standard)
