Medium Voltage Power Cable Manufacturers in China: What Buyers Should Know

China is a global leader in medium voltage (MV) power cable manufacturing, producing cables rated from 6 kV to 35 kV per IEC 60038 for industrial, utility, and infrastructure projects. Buyers must evaluate manufacturers for quality, compliance, and reliability to ensure safe and efficient power distribution. 

1. Overview of China's MV Power Cable Market

China's MV power cable market is driven by rapid industrialization, urbanization, and renewable energy growth, with a projected market size of $25 billion in 2025. Key clusters include Jiangsu, Zhejiang, and Henan Province, offering advanced R&D and supply chains. Manufacturers produce XLPE- or EPR-insulated cables with SWA armoring for applications in manufacturing, mining, and utilities, complying with IEC 60502-2. Buyers benefit from competitive pricing but must prioritize quality to avoid counterfeit issues.

2. Criteria for Selecting MV Power Cable Manufacturers

Buyers should evaluate manufacturers based on the following criteria:

• Certifications: Compliance with IEC 60502-2, TUV, UL, CCC, or CE, verified by accredited bodies.
• Production Capacity: Ability to scale for large projects (e.g., 50,000 m/month).
• Quality Control: In-house testing for insulation resistance (>1000 MΩ/km), partial discharge (<10 pC), and flame-retardant properties (IEC 60332-3).
• Customization: Tailored options (e.g., conductor size, insulation type, armoring).
• Reputation: Export history, customer feedback (e.g., ≥96% on-time delivery), and trade show participation (e.g., Elektro 2025).
