YJV Cable Medium-Voltage Related Knowledge
Medium-Voltage Range: YJV focuses on cables in 3.6/6kV, 8.7/10kV, 18/30kV, and 26/35kV grades, designed for distribution applications with extremely high stability and efficiency requirements.
Advantages of Oxygen-Free Copper Conductors: Resistance ≤0.017241Ω·mm²/m at 20℃, minimizing energy loss and voltage drop, ensuring stable power supply to critical loads.
Advantages of XLPE Insulation: Withstands long-term operation at 90℃ and short circuit at 250℃ (5 seconds), moisture-resistant, chemically resistant, UV-resistant, and anti-aging, suitable for extreme industrial and outdoor environments.
Grade Matching to Application Scenarios: 3.6/6kV suitable for industrial machinery; 8.7/10kV suitable for urban core power distribution; 18/30kV-26/35kV suitable for critical infrastructure (airports, railways, data centers).
Competitive Advantages of YJV Medium Voltage Cables
Ultra-High Conductivity: Oxygen-free copper conductors have 30% higher conductivity than aluminum cables, reducing energy loss and improving transmission efficiency, crucial for energy-saving projects.
Excellent Heat Dissipation: The inherent thermal conductivity of copper prevents overheating during full-load operation, thereby extending cable life and reducing maintenance costs.
Comprehensive Environmental Adaptability: XLPE insulation can withstand temperatures from -40°C to 90°C, humid environments, acid and alkali corrosion, and UV radiation, making it suitable for indoor, outdoor, overhead, and underground installations.
Global Compliance Certifications: Certified by IEC 60502-1, CE (EN 50267), SASO (Saudi Arabia), KEBS (Kenya), and INMETRO (Brazil), it easily clears customs in Europe, Africa, and Southeast Asia.
Reliability in Critical Projects: Low failure rate in high-risk scenarios (such as hospitals and data centers), easy to maintain, and a service life exceeding 30 years, thus reducing long-term operational risks.

Frequently Asked Questions (FAQs)
Q1: Why is YJV the preferred choice for critical infrastructure such as data centers?
A1: Data centers require zero-interruption power. YJV uses oxygen-free copper conductors, ensuring ultra-low resistance and minimal voltage drop, thus providing stable power. Its XLPE insulation layer has excellent heat dissipation performance and a service life of over 30 years, with a low failure rate, perfectly meeting the high reliability requirements of data centers and other critical facilities.
Q2: What are the differences between YJV and YJV22 under different installation methods?
A2: YJV is an unarmored cable suitable for indoor, overhead, or underground installation, but requires additional protection (e.g., using cable conduits). YJV22 features double-layer steel tape armor and can be directly buried without additional shielding. YJV is suitable for environments with minimal mechanical impact; YJV22 is suitable for harsh underground environments requiring strong protection.
Q3: Can YJV cables be customized for the tropical climate of Southeast Asia?
A3: Absolutely! We customize YJV cables with a UV-resistant PE sheath to withstand strong tropical sunlight and upgrade moisture-proof insulation for high-humidity environments. An optional anti-oxidation copper coating prevents corrosion. All tropical-specific YJV cables are SIRIM/SNI certified and fully compliant with Malaysian, Indonesian, and Thai standards.
Q4: What certifications are required for YJV cables to enter the African market?
A4: Key certifications for entering the African market include SONCAP (Nigeria), KEBS (Kenya), and SASO (Saudi Arabia), as well as IEC 60502-1 compliance. We offer complete certification solutions and assist you with the local registration process. Our YJV cables meet all regional quality and safety standards, ensuring smooth customs clearance and entry into the African market.
