ZR Flame Retardant Advantages: Complies with IEC 60332-3-22 flame retardant standards, effectively suppressing flame spread and reducing toxic fumes, crucial for enclosed spaces such as high-rise buildings and power plants.
XLPE Insulation Performance: High dielectric strength, excellent thermal stability (long-term operation at 90℃), strong aging/moisture resistance, suitable for various climates and industrial environments worldwide.
Voltage Rating Matching Guidelines: 3.6/6kV suitable for residential/commercial building power distribution; 8.7/10kV suitable for industrial plant power supply; 18/30kV-26/35kV suitable for power plant auxiliary systems and urban main power grids.
Competitive Advantages of ZR-YJV Medium Voltage Cables
Superior Fire Safety: The ZR flame-retardant design complies with global fire safety regulations, minimizing fire risks in densely populated or critical facilities, making it ideal for high-rise buildings, hospitals, and data centers.
High-efficiency power transmission: Utilizing cross-linked polyethylene (XLPE) insulation and oxygen-free copper conductors, it reduces power loss by 35% compared to traditional polyvinyl chloride (PVC) cables, thereby lowering long-term operating costs for energy-intensive projects.
Wide environmental adaptability: Operates in a temperature range of -40°C to 90°C, resistant to moisture, chemical corrosion, and UV radiation, suitable for diverse climates in Europe, Africa, Southeast Asia, and the Middle East.
Global market access: Fully compliant with IEC 60502-1, CE (EN 50267), SASO (Saudi Arabia), KEBS (Kenya), and INMETRO (Brazil) standards, providing complete certification documentation to ensure smooth customs clearance.
Diverse application scenarios: Suitable for commercial buildings, industrial workshops, power plants, urban underground pipe networks, and renewable energy auxiliary systems, meeting stringent fire protection and energy efficiency requirements.

Frequently Asked Questions: ZR-YJV Medium Voltage Flame Retardant Cable (Global Application FAQs)
Q1: What does "ZR" mean in ZR-YJV cable? Q: What are its flame retardant properties?
A1: "ZR" stands for flame retardant (Zǔ Rán), conforming to IEC 60332-3-22 standard. It can inhibit the spread of flames along the cable for 90 minutes after a fire starts, with low smoke concentration and low emissions of toxic gases. The flame retardant rating is equivalent to the European Class C flame retardant standard, meeting CE EN 50267 requirements, and is safe for use in enclosed public and industrial locations.
Q2: What is the difference between ZR-YJV and ZR-VV medium-voltage cables?
A2: The main difference lies in the insulation material. ZR-YJV uses XLPE insulation (capable of long-term operation at 90℃), offering higher temperature resistance and energy efficiency. ZR-VV uses PVC insulation (maximum 70℃), which is more economical but has lower thermal stability. ZR-YJV is suitable for high-temperature industries and high-energy-efficiency projects; ZR-VV is suitable for low-temperature environments with tighter budgets.
Q3: Is ZR-YJV suitable for the low-temperature regions of Northern Europe?
A3: Yes! We can customize ZR-YJV insulation with low-temperature resistant XLPE insulation (-40℃) for the Nordic region. It effectively prevents embrittlement and cracking in low-temperature environments, meeting the EN 50267 low-temperature standard. This product has obtained CE certification and is widely used in Nordic city power grids and industrial plants. We have a local warehouse in Germany to ensure fast delivery within 2-5 days and provide timely technical support.
Q4: What certifications are required for ZR-YJV to enter the African market?
A4: For the African market, ZR-YJV has obtained KEBS (Kenya), SONCAP (Nigeria), and SABS (South Africa) certifications, fully complying with local standards. It also complies with the IEC 60502-1 global standard. We provide complete test reports and customs clearance documents. We have warehouses in Kenya and South Africa, providing 3-7 day local delivery and on-site installation guidance for large projects.
