High-precision oxygen-free copper
Copper purity reaches up to 99.9%. Power cord conductors are in use at Ø8.0.
Oxygen-free copper rod undergoes multiple wire drawing, stranding, and annealing processes, resulting in an elongation of over 23%. Annual copper procurement exceeds 5,000 tons.
Environmentally friendly, we adhere to the ROHS 2.0 standard and have a comprehensive HSF toxic and hazardous material management system. All materials undergo regular third-party ROHS, REACH, and other environmental testing reports.
After 30,000 flex cycles, the core wire withstands a water-immersion voltage of 1.5K for 5 minutes without breakdown. It withstands 80±2°C for 168 hours without change.
The temperature rise is less than 30K after applying 1.25 times the current. After 16 hours in a -15±2°C freezer and a 2000g impact, the plug shows no change.

Q: Can you customize Power Cord with special specifications?
A: Of course. We can customize power cords with different lengths, plug shapes and power carrying capacities to meet the needs of your special industrial equipment or electrical products, such as customizing plugs with special locking devices for specific equipment.
Q: How do you ensure product quality?
A: In production, the purity and cross-sectional area of the conductor material are strictly tested, the insulation material must pass the voltage resistance, wear resistance and aging resistance tests, and the plug and socket interface part is tested for plug-in life. Only products that pass all tests will be packaged and shipped.
Q: What are the characteristics in customer service?
A: We provide professional pre-sales consulting services, and accurately recommend the most suitable power cord products based on the information provided by the customer on the power of the electrical equipment, usage scenarios, target markets, etc. For example, if the customer is an export-oriented enterprise, we will help understand the power cord standards of the target country and provide solutions. In terms of after-sales, if the customer finds quality problems with the power cord, we will respond quickly, provide replacement or repair services in a timely manner, and record and analyze customer feedback in detail, continuously improve product quality and production processes, and improve customer satisfaction.
Q: What are your Power Cord's environmental protection measures?
A: We attach great importance to environmental protection. In the production process of power cords, we try to use environmentally friendly materials, such as recyclable insulation materials and conductor coatings that meet environmental standards. At the same time, we are constantly optimizing production processes, reducing energy consumption and waste emissions, ensuring that our products meet customer needs while also complying with current environmental requirements and trends, and contributing to sustainable development.
