Certification
UL3239 24AWG silicone rubber insulated wire has been rigorously tested and certified to UL's high-voltage wire standards. It meets requirements for dielectric strength, insulation thickness, flame retardancy, and high-temperature resistance, ensuring safe operation in harsh environments. The silicone insulation has passed the UL VW-1 vertical flame test, demonstrating flame retardancy. Both the conductor and insulation materials are RoHS-compliant, ensuring they contain no hazardous substances such as lead or mercury. These certifications not only demonstrate safety and reliability, but also make it suitable for global markets requiring compliance with international safety and environmental standards.
Package
Our Package
The cables are neatly wound onto paper, wooden or plastic drums, with appropriate specifications and support strength selected according to customer needs.
Provide outer box packaging, pallet loading and reinforcement measures according to the logistics requirements of different destinations to ensure the safe arrival of cables
The cables will be neatly coiled and placed in sturdy cardboard or wooden boxes, supplemented with moisture-proof and shock-proof materials to ensure that they remain intact and safe during packing and transportation.
Production Line
Our production lines are equipped with advanced automated equipment, covering the entire process from high-purity copper wire drawing, precision stranding, silicone or PVC insulation extrusion, to cabling, sheathing, testing and packaging. Each step is completed under strict quality control to ensure that the cables meet international standards in terms of conductivity, flexibility, temperature resistance and safety, providing customers with reliable, stable and high-performance cable products.
