For 27 years since starting his business in Lanzhou, Jin Yinqiang has maintained a consistent habit: whenever he has a spare moment, he walks into the production workshops to communicate with employees about processes and technologies, listening to their new ideas and needs.

On a morning in early summer, at a factory located beside Zhongbang Avenue in Anning District, Lanzhou, the chairman of Lanzhou Zhongbang Wire & Cable Group Co., Ltd., Jin Yinqiang, was seen discussing detailed improvements to production techniques with workers on the shop floor.

"Product quality is our livelihood; every detail must be handled with utmost care," Jin Yinqiang stated. Behind him, on a beam in the workshop, a banner read: "Do it right the first time, do it well the first time, earn respect through quality."

The key to Zhongbang Wire & Cable's success in selling across China and entering international markets such as Central Asia lies in its quality.

In the corporate culture exhibition center, a series of products including power cables, mining cables, special cables, and photovoltaic cables are displayed, resembling a "cable kingdom."

One ultra-high voltage power cable is as thick as an adult's wrist. Upon closer inspection, its cross-section consists of five equal fan-shaped segmented conductor blocks, meeting the requirements for long-distance, high-capacity, and low-loss power transmission in 110 kV grids. As early as 2012, Lanzhou Zhongbang overcame this technical challenge.

A low-smoke, zero-halogen, flame-retardant household wire with a cross-section of only 2.5 square millimeters is positioned as a high-end safety product due to its low smoke emission, flame retardancy, and absence of harmful gas release when exposed to fire. This innovation earned Lanzhou Zhongbang the second prize of the Gansu Provincial Science and Technology Progress Award in 2014.

A reel of PV1-F photovoltaic cable, certified by Germany's TÜV Rheinland, is exported to international markets including Central Asia. The confidence in this product's robust quality stems from the irradiation room put into operation by Lanzhou Zhongbang in 2010—one of only five such facilities in the province—effectively enhancing cable weather resistance and extending product lifespan.

Jin Yinqiang acknowledged that these are practical innovations achieved through the diligent efforts of employees, with many effective methods originating from grassroots staff directly driving the company's quality improvement and efficiency gains. In his view, Zhongbang's future lies in innovation and creation.

Over the years, Lanzhou Zhongbang has earned numerous honors, including "China Well-Known Trademark," "National Inspection Exemption," and the "Gansu Provincial People's Government Quality Award," and has been repeatedly listed among the "Top 20 Most Competitive Enterprises in China's Wire and Cable Industry." Its solid quality has won market recognition, with products entering the procurement lists of enterprises such as State Grid, China Southern Power Grid, PetroChina, and China Huadian.

Quality stems from technological innovation as well as strong market awareness.

In August 1999, during the Lanzhou Investment and Trade Fair, Jin Yinqiang, who was passing through Lanzhou, visited the venue and discovered that there were no private cable enterprises in Lanzhou at the time. Having been engaged in cable sales and production in Zhengzhou for over a decade, he identified a potential business opportunity and decided to invest in building a factory in Lanzhou.

On October 18, 1999, Zhongbang Wire & Cable Company broke ground. By the end of that month, Jin Yinqiang visited Lanzhou Public Transport Company, proposing to invest 1 million yuan to place advertisements on 1,800 buses in Lanzhou for one year, pioneering bus advertising in the city.

On March 26, 2000, 157 days after the factory construction began, Zhongbang's wire and cable production line, designed with an annual capacity of 100 million yuan, was completed and put into operation. By then, the advertising slogan "Zhongbang Cables, short by one meter, compensate tenfold" had become a household phrase in Lanzhou.

Twenty-seven summers later, the company's designed annual production capacity has reached 10 billion yuan. However, Jin Yinqiang's commitment to product quality remains unchanged.

He firmly stated, "It's still the same today: Zhongbang Cables, short by one meter, compensate tenfold."

True to this promise, Jin Yinqiang's demand for product quality reflects a resolute determination.

Once, due to localized oil leakage from equipment, a batch of cables developed quality flaws. Jin Yinqiang immediately decided to scrap the entire batch, valued at 6 million yuan, and shut down the production line for a comprehensive seven-day rectification.

"Quality first, integrity to customers" is the fundamental principle for Zhongbang. For the sake of the company's enduring legacy, Zhongbang would rather pay some "tuition fees" than damage its brand. Jin Yinqiang remarked, "The best service is service that requires no after-sales service."

The company's quality, brand, and development opportunities also stem from clear strategic judgment.

From the outset, Jin Yinqiang was determined to focus deeply on the power equipment sector, with wire and cable as the main business. He noted that coal, oil, and natural gas are non-renewable resources, while Gansu and many regions across China were already developing new energy power. Over the past 27 years, Zhongbang has not only seized the historical opportunity of the Western Development Strategy but also capitalized on initiatives such as "West-East Power Transmission," "Dual Carbon" goals, and "Energy Low-Carbon Transition." It has achieved mutually beneficial collaboration with provincial enterprises like Jinchuan Group and Jiugang Group in copper and aluminum raw materials.

In March 2026, Jin Yinqiang was awarded the honorary title of "Outstanding Entrepreneur of Gansu Province" by the provincial Party committee and government.

"We always follow the Party's guidance, actively integrate into the overall development of the nation and the times, unwaveringly pursue the path of quality and branding, and build a century-old Zhongbang," Jin Yinqiang expressed with determination and confidence as the interview concluded.
