ZR-YJV Fire Retardant Cable 0.6/1kV To 33kV Heat Resistant Cables

ZR-YJV is a low-voltage copper core power cable with a flame-retardant design that helps limit the spread of flame along the cable's path, making it ideal for building wiring and industrial installations, especially in locations where fire safety requirements specify the use of flame-retardant cables. It typically features copper conductors, cross-linked polyethylene (XLPE) insulation, and a sheath system that meets the relevant standard flame-retardant rating requirements. ZR-YJV is widely used in locations where cable density is high and line safety is a priority, such as fixed installation environments like cable trays, conduits, cable ducts, risers, and equipment rooms.

For cross-border buyers, if a project requires a flame-retardant rating but does not want to use the Low Smoke Halogen-Free (LSZH) specification, ZR-YJV is a practical upgrade to standard YJV.

Typical Rated Voltage: 0.6/1 kV

Please confirm the flame-retardant rating required in your project's standards and Bill of Quantities (BOQ).

Availability depends on conductor grade and required flame retardant standard.

• Flame Retardant Performance for Line Safety

  Designed to help limit the spread of flame along cable lines, ensuring safety in risers, corridors, shafts, and high-density cable tray installations.

• XLPE Insulation for Stable Low-Voltage Distribution

  XLPE insulation provides reliable dielectric and thermal properties for continuous load building feeders and industrial power distribution.

• A More Cost-Effective Upgrade than Standard YJV

  Provides a higher fire safety rating while maintaining a familiar cable structure, facilitating efficient installation and termination by contractors.

• Suitable for commercial buildings and industrial sites

  Commonly used in hospitals, shopping malls, office buildings, factories, and public utility buildings where fire safety regulations require flame-retardant cables.

• Facilitates EPC procurement and repeat supply

  Standard configurations and common sizes support bill of materials matching, inventory planning, and phased project delivery.

• Low-voltage power distribution main and branch feeders
• Cable trays, conduits, cable trays, risers, and shafts
• Equipment rooms, switchgear rooms, and electrical corridors
• Commercial buildings, high-rise power distribution lines, and public facilities
• Industrial plants requiring flame-retardant cable lines

1. Copper Conductor Production

   Copper is drawn and stranded to meet conductor resistance and flexibility requirements.

2. XLPE Insulation Extrusion and Crosslinking

   XLPE insulation is extruded and crosslinked to ensure stable electrical and thermal properties in low-voltage applications.

3. Core Identification and Assembly

   After identification, the cores are laid in the specified number, using fillers and adhesives where necessary to maintain a stable geometry.

4. Flame-Retardant Sheath Formulation

   The selection and processing of the outer sheath compound system meet the flame-retardant rating requirements of relevant standards.

5. Sheath Extrusion and Finishing

   The sheath is coated with controlled thickness and surface quality, followed by printing and traceability marking.

6. Routine Testing and Compliance Checks

   Typical checks include conductor resistance, insulation thickness, spark testing, voltage testing, dimensional verification, and sheath integrity checks. Flame-retardant performance verification is performed according to the required rating.

1. When the tender requires the use of flame-retardant low-voltage power cables for building or industrial power distribution lines, please select ZR-YJV cables.
2. Please confirm the flame retardancy rating required in the reference standards to avoid test category mismatches.
3. Select the number of cores based on the power distribution scheme and neutral/protective conductor design.
4. Select the cross-sectional area based on current, distance, grouping, ambient temperature, and allowable voltage drop.
5. If your project requires low-smoke halogen-free performance, please select the LSZH model instead of the standard ZR sheathed system.
