Anhui Huanrui Heating scales self-regulating heating cables to 260 C

Anhui Huanrui Heating Manufacturing says it has moved its self-regulating heating cable line to 260 C series production, adding momentum to orders and signaling a new stage in its push to replace imports. The Feidong, Anhui-based company also highlights major gains in patents, certifications and overseas sales as local policymakers back tech-driven manufacturers.

Why it matters: - Anhui Huanrui Heating Manufacturing has moved from low-end cable heating to high-temperature, self-regulating products used in major industrial and transportation systems. - The company’s progress shows how a county-level industrial policy push can support a specialized manufacturer’s upgrade from domestic substitute to global supplier. - The shift to 260 C series production expands the company’s addressable market in energy, infrastructure and heavy industry.

What happened: - Huanrui Electric Heating, based in Feidong county in Hefei, Anhui province, says it began mass production of self-regulating heating cable products with heat resistance up to 260 C at the start of this year. - Founder and chairman Ji Chengzhi said the new production run has driven a fresh increase in orders. - The company says 110 C heating cables produced at its plant were used in Fuxing high-speed trains, including the CR450 model, at the end of last year. - The cables help keep water tanks, drain pipes and other equipment operating in extreme cold.

The details: - Self-regulating heating cables generate heat after power is applied, then automatically reduce output as ambient temperature rises to keep temperature within a set range. - Huanrui Electric Heating says the cables are used in petrochemicals, high-speed rail, infrastructure construction and other sectors. - Before 2014, domestic Chinese electric heating materials generally did not exceed 85 C in heat resistance, and key components were dominated by foreign suppliers. - In 2014, Ji set a new mission for the company: replace imports with in-house technology and serve global industry with Chinese solutions. - The company later formed an Anhui “115” innovation team and established a postdoctoral research station and an engineering technology research center for high-performance self-regulating heating cables. - In 2018, Huanrui Electric Heating says it achieved breakthroughs in material design, production technology, testing and integrated thermal control systems, completing import substitution. - The company says it shifted from a single-product supplier to an EPC provider covering design, manufacturing, installation and after-sales service. - In 2023, the company launched full-scale mass production of high-performance self-regulating products with heat resistance up to 200 C. - That same year, Huanrui Electric Heating says it won its first framework tender from China National Offshore Oil Corp. for heating materials. - In 2025, the company raised the heat resistance of its mass-produced high-performance self-regulating products to 260 C. - Huanrui Electric Heating says it holds 1 international invention patent and 16 Chinese national patents. - The company also says it has built a digitalized workshop and its testing center has CNAS accreditation, covering quality control from raw materials to finished products. - The company says its products have passed EAC, CE, BV and CSA certifications. - Huanrui Electric Heating says it now serves more than 50 countries and regions, including Russia, the UK, Poland, Finland and Brazil.

Between the lines: - The company’s timeline tracks a broader industrial playbook in China: move from basic manufacturing to higher-value, standards-driven products with export potential. - Feidong county appears to be using funding, policy support and recognition programs to concentrate resources around specialized and innovative firms. - The combination of patents, certifications and EPC capability gives Huanrui Electric Heating a stronger position in markets where reliability and compliance matter more than price alone.

What's next: - Huanrui Electric Heating is likely to keep pushing higher-temperature products and broader system-level offerings as it competes in industrial heating markets. - Feidong officials say they will focus next on key industrial sectors, leading enterprises and cluster development across upstream and downstream supply chains. - The county will also continue supporting independent innovation and industrial upgrading through policy tools and subsidies. - Over the past three years, Feidong county says it provided 10.58 million yuan in awards and subsidies to 66 companies for technical centers and industrial design centers, 14.15 million yuan to 105 companies for brand development, specialization and new-product development, and more than 53 million yuan to 357 companies for loan interest subsidies. - Feidong’s industry bureau says it provided Huanrui Electric Heating 1.224 million yuan in subsidies over the past three years, including 224,000 yuan for loan interest support.
