After 25 years of development, the company has grown into a specialized, innovative "little giant" enterprise and has been designated a "High-Tech Enterprise" for nine consecutive years. In 2023, the company achieved revenue of 345 million yuan and an annual production capacity of 54,000 kilometers, enough to more than circle the Earth. Its products cover the energy, transportation, and engineering sectors, serving the entire nation and selected international markets.

1. Deeply Engaging in the Cable Industry, Setting an Industry Benchmark

Guizhou Tianhong Zhiyuan Wire and Cable Co., Ltd. (hereinafter referred to as "Guizhou Tianhong") was established in 1999 and settled in the Huishui County Economic Development Zone, Guizhou Province, in 2012. After 25 years of development, the company has grown into a specialized, innovative "little giant" enterprise and has been designated a "High-Tech Enterprise" for nine consecutive years. In 2023, the company achieved revenue of 345 million yuan and an annual production capacity of 54,000 kilometers, enough to more than circle the Earth. Its products cover the energy, transportation, and engineering sectors, serving the entire nation and selected international markets.

2. Core Technology Breakthrough: Dual Innovation in Safety and Durability

Fire-Resistant Cable Technology
To address the flammability and heat resistance of traditional cables, Guizhou Tianhong has developed mineral-based fire-resistant cables. Using specialized materials such as mica tape and ceramic silicone rubber to coat the conductor, the cables can sustain power for over three hours in flames of 950°C to 1000°C and withstand short-term temperatures of up to 1083°C, providing critical power support for fire rescue operations. This technology fills a gap in the domestic market for fire-resistant and high-temperature cables, with orders for related products exceeding 12 million yuan in the first quarter of 2024.

Precision Processing Enhances Performance
Through improved wire drawing processes, copper conductor diameters can be reduced to 0.12 mm (close to the thickness of a human hair), and twisting technology enhances flexibility. The insulation eccentricity of medium and high voltage cables is controlled at 3%-8%, exceeding the national standard of 15%, significantly reducing the risk of electrical leakage.

Environmentally Friendly Materials
The company's low-smoke, halogen-free series cables utilize environmentally friendly materials such as polyolefins to replace traditional PVC. They emit no toxic gases and generate low smoke during combustion, making them widely used in public settings such as hospitals and schools.

III. Green Intelligent Manufacturing: A Practical Example of Energy Saving and Carbon Reduction

Guizhou Tianhong integrates green development concepts throughout its entire production process:

Resource Recycling: Investment in a cooling water circulation system saves an average of 150 tons of water per month; the use of energy-saving motors reduces monthly electricity consumption by 22%.

Process Optimization: Through the development of aluminum alloy cables, aluminum replaces copper, and combined with a compacting process, the fill factor is increased to 93%, achieving a balance between lightweight and high performance.

Green Product Development: The company develops environmentally friendly products such as photovoltaic cables and new energy vehicle cables, achieving provincial "Green Factory" certification in 2021 and TÜV Rheinland certification.

IV. Collaborative Innovation between Industry, Academia, and Research to Drive Industrial Upgrading

The company has established two R&D teams and collaborates with universities such as Harbin University of Technology and Guizhou University on technical research. They have been granted 17 utility model patents and 3 invention patents. Their ultra-flexible fire-resistant cable, which utilizes Category 5 conductors and elastomeric materials, combines high load-bearing capacity with flexibility and has been used in applications such as elevator shafts.

V. Serving National Strategies and Enabling Major Projects

As a Tier-1 material supplier for State Grid and China Southern Power Grid, Guizhou Tianhong's products are widely used in landmark projects such as the Three Gorges Dam, Guiyang Longdongbao International Airport, and the Guiyang-Huangshan Expressway. The company has also established long-term partnerships with state-owned enterprises such as China Railway Construction and China Huadian.

Future Outlook

Guizhou Tianhong will continue to be guided by market demand, deepen its intelligent and green transformation, and promote technological iteration in niche areas such as aluminum alloy cables and new energy cables, injecting innovative momentum into the development of new industrialization.
