WDZ-BYJ LSZH House Wiring Cables 450/750V Copper Flame Retardant

WDZ-BYJ is a low-smoke, halogen-free, flame-retardant single-core building cable designed for safer indoor power distribution and fixed wiring. It uses copper conductors and halogen-free cross-linked insulation, helping to reduce the concentration of corrosive gases and smoke in a fire while providing stable electrical performance for everyday building loads. WDZ-BYJ is ideal for modern commercial buildings, public facilities, transportation hubs, and industrial buildings with extremely high safety regulations and evacuation requirements.

The low-smoke, halogen-free construction helps reduce dense smoke and corrosive gases, ensuring safer evacuations and reducing secondary damage to equipment.

The flame-retardant design helps limit the spread of flames along wiring lines, ensuring the safety of riser, shaft, and cable tray systems.

Cross-linked insulation supports stable operation and improves the heat resistance of building wiring for long-term use.

Single-core specification contributes to neat distribution panel wiring and clear circuit layout; multiple colors are available, simplifying phase sequence and circuit marking.

High-frequency building wiring suitable for contractors, distribution panel repair shops, and electromechanical engineering, ideal for inventory management and repeat purchases.

• Enhanced Fire Safety in Buildings and Public Spaces
• Provides Flame-Retardant Protection for Cable Lines
• Cross-Linked Insulation Ensures Reliable Power Supply
• Neat and Professional Installation and Easy Identification
• Strong Distributor and Project Needs

The common rated voltage for WDZ-BYJ building wiring is 450/750V.

Some project standards may specify different rated voltages; please select according to tender requirements and local regulations.

• 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm², 35 mm², 50 mm², 70 mm², 95 mm², 120 mm², 150 mm², 185 mm², 240 mm²

• 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm², 35 mm² mm²

• Small sizes are typically solid or stranded (depending on market/specification)
• Medium and large sizes are typically stranded for ease of handling and termination

• Building distribution panels and sub-distribution lines
• Riser, shaft, trunking, and conduit cabling (fixed installation)
• Public buildings: airports, hospitals, schools, shopping malls, stadiums
• Equipment rooms and machine rooms requiring reduced corrosive gases
• Industrial buildings and utilities with higher fire safety requirements

• Conductor: Copper (solid or stranded, depending on size/specification)
• Insulation: Halogen-free cross-linked compound (LSZH/HFFR type, depending on specification)
• Cable Form: Single-core building wire (typical BYJ structure without outer sheath)
• Installation Method: Fixed installation in conduits, trunking, trays, protective layers, or enclosed wiring

• If your project requires low-smoke, halogen-free, flame-retardant building wiring for indoor fixed installations, select WDZ-BYJ.
• Select the cross-sectional area based on load current, line length, grouping, and allowable voltage drop.
• Using a multi-color scheme can speed up commissioning and reduce maintenance errors.
• If you require an outer sheath, mechanical armor, or resistance to outdoor environments, select a sheathed or armored cable series that matches the environment.
