WIRE & CABLE CERTIFICATED: Guarantee of Safety, Compliance and Market Competitiveness

In the global trade of electrical products, as the "capillaries" of the power system, wire’s certification are not only a symbol of technical strength but also the key to market access. Behind different certification systems lies a profound game of regional regulations, industrial and technology. At present, the regionalized matrices of the major global certification systems include UL in North America, VDE in Germany, JIS in Japan, and CQC in China, etc.



As a masterpiece of Underwriters' laboratories, UL standards have established a precise temperature grade pyramid. Its certification logic breaks the mold, replacing the long-term operating temperature of conductors with "rated temperature", and establishing a material life model based on the rate of change in elongation at break. This design enables UL cables to form a technical moat in the North American market, making it difficult for uncertified products to enter the procurement systems of companies like Walmart and General Electric.

The VDE certification, established with the German Association of Engineers, each link must be strictly tested. As cable H05Z-K , its rated temperature of 90℃ has been verified by the standard EN50525-3-41 , and it is required that the cross-linked low smoke zero halogen material maintain a service life of 25 years under 300/500V. Independently created by VDE Laboratory, the 18-item Test covers terminal pull-out force, flame retardancy, and mechanical strength and so on, making certified products synonymous with high-end manufacturing in Europe.

The JIS C 3406 standard, which originated from the Japanese automotive industry, is specifically designed for low-voltage cables in automobiles. It is required that the ethylene resin insulation layer can still withstand 1000V after being baked at 120℃ for 120 hours. Meanwhile, it needs to pass the low-temperature bending at -40℃, flame retardancy and oil resistance tests. This "extreme contrast" certification logic corresponds to the extreme environmental adaptability requirements of the Japanese automotive industry chain for cables.



As a national mandatory certification, the CQC certification serves as the "admission ticket" for entering the Chinese market. Its 70℃ temperature resistance may seem regular, but it has eliminated a large number of non-standard products.

In the cross-cultural dialogue among technical indicators, the differences in temperature requirement are reflected. The 105℃ grade in the UL standard is specifically designed for chemical corrosive environments, while the Japanese standard JIS C 3406 pays more attention to the thermal cycle shock (120℃→-40℃). This difference stems from their applications: the chemical industry in the United States is developed, the automotive electrical system in Japan is complex, and the industrial equipment in Germany pursues long-term stability.

The game in materials science: VDE certification favors the low smoke and halogen-free properties of cross-linked polyolefins (XLPO), which comply with European environmental protection regulations; The UL standard allows specific PVC materials to be used at temperatures below 105℃, embodying the American tradition of pragmatism. Behind the material selection lies the collision of regional values between environmental protection and cost control.



As a 36-year-old manufacturer of high-temperature resistant wires, HANSTAR adheres to the principle of putting customers at the center and prioritizing safety. As early as 1994, we obtained UL certification ahead of similar enterprises and became one of the first to acquire this international certification in China. Under the triple guarantee of safety, compliance and market competitiveness, we have successively obtained authoritative certifications such as VDE and CQC. As both the guardians of the safety bottom line and the "golden key" to expanding the global market, certification have become the DNA of an enterprise's competitiveness in today's increasingly complex electrical product market.
