Application
HOFR NBR rubber ultra-flexible pure copper welding cable is mainly used for secondary high current connection of automated or handheld metal arc welding machines. It is particularly suitable for assembly lines, conveyor systems, machine tools, automated welding production lines and spot welding equipment. It can maintain excellent electrical and mechanical properties under extremely harsh and high-intensity use conditions and is an ideal choice for professional welding equipment.

Feature

HOFR NBR rubber extra flexible pure copper welding cable is a high-performance welding cable designed for high-current connections. The cable uses high-conductivity bare soft copper conductors (category 5 and 6 conductors in accordance with IEC 60228 and DIN VDE 0281 standards) to ensure excellent electrical performance and excellent flexibility. The insulation layer is made of oil-resistant and wear-resistant NBR nitrile rubber material, which has excellent heat resistance, oil resistance, and mechanical wear resistance. The rated voltage is 600V, the test voltage is up to 2500V, and it can work stably in a wide temperature range of -30℃ to +90℃.
Certification
UL certification is a safety standard widely recognized in the North American market. It complies with UL and other relevant specifications, allowing welding cables to smoothly enter the US, Canadian and other international markets, and enhance the global competitiveness of products. UL certification not only means that product quality meets international standards, but also enhances customer confidence, enhances the market influence of the brand, and enables enterprises to stand out in industry competition
