WDZ-YJY Low Smoke Zero Halogen Cable 3.6/6kV 6/10kV 12/20kV Multicore Cable

WDZ-YJY Low-Voltage Power Cable

WDZ-YJY is a low-voltage power cable specifically designed for indoor power distribution. Its low-smoke halogen-free (LSZH) performance effectively enhances fire safety. This cable features copper conductors, cross-linked polyethylene (XLPE) insulation, and a low-smoke halogen-free outer sheath system, suitable for installation in risers, shafts, corridors, equipment rooms, and high-density cable trays. WDZ-YJY is commonly used in commercial buildings, public facilities, transportation infrastructure support areas, and industrial buildings where strict requirements exist for reducing smoke concentration and corrosive gas emissions during fires.

For cross-border procurement, WDZ-YJY is a compliant low-voltage cable suitable for projects seeking a low-smoke halogen-free (LSZH) solution without additional armoring, balancing safety and installation efficiency.

Reasons the Buyer Chooses WDZ-YJY

• Low Smoke Halogen-Free Sheath, Creating a Cleaner Evacuation Environment Using a low smoke halogen-free cable system reduces smoke concentration and corrosive gases during a fire, thereby improving evacuation visibility and reducing equipment corrosion damage.
• Cross-linked Polyethylene (XLPE) Insulation, Ensuring Stable Thermal Performance The cross-linked polyethylene (XLPE) insulation provides reliable low-voltage distribution under continuous load, making it suitable for building feeders and distribution circuits.
• Practical installation suitable for cable trays, risers, and conduits. The unarmored construction provides sufficient flexibility for common building wiring routes while maintaining a robust insulation and sheathing system.
• Ideal for public buildings and projects with high compliance requirements. Commonly used in hospitals, schools, shopping malls, stadiums, transportation infrastructure areas, and high-rise buildings where regulations explicitly specify Low Smoke Halogen-Free (LSZH) requirements.
• Easy to procure, suitable for EPC and phased delivery. Universal configurations and reel designs facilitate Bill of Materials (BOQ) matching, repeat orders, and on-time delivery.

Typical Applications

• Main low-voltage feeders and branch feeders within buildings
• Cable trays, risers, shafts, corridors, and equipment rooms
• Switchgear, distribution panels, and service lines
• Commercial, residential high-rise buildings, and public utilities
• Industrial buildings requiring indoor wiring to meet Low Smoke Halogen-Free (LSZH) requirements

Process and Manufacturing Notes

1. Copper Conductor Production Copper is drawn and stranded into specified conductor grades to achieve stable resistance and suitable installation flexibility.
2. XLPE Insulation Extrusion and Crosslinking The insulation layer is extruded and crosslinked to form a stable electrical layer suitable for low-voltage distribution applications.
3. Core Identification and Wiring Cores are color-coded or numbered and stranded in specified numbers, with filler and binding tape added where necessary to ensure stable cable geometry.
4. LSZH Sheath Composite and Extrusion Extruded low-smoke halogen-free sheath composite systems provide line protection and specific fire resistance.
5. Routine Testing and Inspection Typical inspections include conductor resistance, insulation thickness, spark testing, voltage testing, and dimensional verification. Relevant documents can be provided according to project requirements.

Specifications

Selection Guide

• When your project requires low-smoke halogen-free low-voltage power, please select WDZ-YJY.
• Suitable for indoor building power distribution circuits, featuring a practical, unarmored structure.
• Select the number of cores based on the requirements of the neutral and protective earth (PE) conductors, and choose the cross-sectional area based on current, line length, wiring configuration, ambient temperature, and permissible voltage drop.
• For underground installations or environments with high mechanical risks, consider using armored low-smoke halogen-free (LSZH) cables. For outdoor environments, select a suitable sheathing system based on UV radiation and environmental conditions.

Frequently Asked Questions

• Applications of WDZ-YJY WDZ-YJY is used for indoor low-voltage power distribution, suitable for applications requiring low smoke halogen-free performance, including feeders and sub-feeders installed in cable trays, risers, shafts, and protected wiring.
• Why does the project specify the use of low smoke halogen-free cable? Low-smoke halogen-free systems reduce smoke concentration and the generation of corrosive gases during a fire, thereby improving evacuation visibility and reducing corrosive damage to electrical equipment.
• Is WDZ-YJY the same as PVC-sheathed XLPE power cable? No. WDZ-YJY typically uses a low-smoke halogen-free sheath compound system instead of standard PVC, designed to improve fire resistance in enclosed wiring.
• Can WDZ-YJY be used outdoors? Outdoor suitability depends on the sheath compound and environmental exposure. If long-term exposure to UV, humidity, or harsh weather conditions is anticipated, please specify the specific conditions for proper matching.
• What information is needed for an accurate quote? Core configuration, cross-section list, total length, required standards, installation route, packaging preferences, and destination.
• Can you provide export packaging and project documentation? Yes. We can provide packaging markings, batch traceability information, routine test records, and export packaging for EPC and distributor sourcing.
