PVC Insulation Performance: High dielectric strength, good chemical corrosion resistance, stable performance in environments ranging from -15℃ to 70℃, suitable for various global climate conditions.
Voltage Rating Matching Guidelines: 3.6/6kV suitable for residential building power distribution; 8.7/10kV suitable for underground cabling in industrial areas; 18/30kV-26/35kV suitable for tunnels and large-scale infrastructure projects.
Competitive Advantages of ZC-VV22 Medium Voltage Cables
Fire Safety: ZC flame retardant design effectively prevents the spread of fire, meets global building fire safety standards, and is ideal for high-density residential and commercial buildings.
Double Mechanical Protection: 22# double-layer steel tape armor resists soil compaction, construction impacts, and rodent damage, allowing for direct burial without additional protective conduits.
Cost-effective and durable: The PVC insulation layer offers excellent abrasion resistance and low maintenance costs, while the oxygen-free copper conductor ensures high conductivity and energy efficiency.
Global market access: Fully compliant with IEC 60502-1, CE (EN 50267), SASO (Saudi Arabia), KEBS (Kenya), and INMETRO (Brazil) standards—complete certification documentation ensures smooth customs clearance.
Suitable for various fire risk scenarios: Perfect for high-rise buildings, shopping malls, industrial workshops, subway tunnels, and urban underground power grids—meeting stringent fire safety requirements.

FAQ: ZC-VV22 Medium Voltage Flame Retardant Cables (Common Global Applications)
Question 1: What does "ZC" in ZC-VV22 cable represent? What is its flame retardant rating?
Answer 1: "ZC" refers to the Chinese flame retardant rating Class C (equivalent to IEC 60332-3-22 Cat. C), meaning that this cable can suppress flame spread for 90 minutes under fire conditions. It produces low levels of smoke and toxic gases, meeting global building fire safety standards (e.g., CE EN 50267 in Europe, GB/T 12666 in Asia), making it ideal for enclosed public spaces.
Question 2: What is the difference between ZC-VV22 and ZC-YJV22 medium voltage cables?
Answer 2: The main difference lies in the insulation material. ZC-VV22 uses PVC insulation (maximum operating temperature 70℃), offering high cost-effectiveness and good chemical corrosion resistance. ZC-YJV22 uses XLPE insulation (maximum operating temperature 90℃), providing higher temperature resistance and higher energy efficiency. ZC-VV22 is suitable for fire-risk scenarios with high budget constraints (e.g., residential buildings); ZC-YJV22 is suitable for high-temperature industrial environments.
Q3: Is ZC-VV22 suitable for the high-humidity coastal areas of Southeast Asia?
A3: Yes! We have customized ZC-VV22 for the coastal areas of Southeast Asia, using corrosion-resistant galvanized steel strips and moisture-proof PVC sheaths to effectively prevent rust and moisture intrusion. This product complies with the SIRIM/SNI certification of Malaysian/Indonesian coastal building standards. It is widely used in high-rise buildings and coastal industrial areas in Southeast Asia, balancing fire safety and moisture resistance.
Q4: What certifications are required for ZC-VV22 to enter the European market?
A4: ZC-VV22 has obtained CE certification (compliant with EN 50267 standard) and a flame retardant test report (compliant with IEC 60332-3-22 standard), making it suitable for the European market. RoHS compliance documents can also be provided upon request. We have warehouses in Europe (Germany, France) enabling local delivery within 2-5 days. Our professional technical team can assist with fire safety verification for projects to meet local building codes.
