A few days ago, Shanghai Zhongtian Aluminum Wire Co., Ltd. made a major breakthrough in the area of ​​large cross-section heat-resistant aluminum alloy wire. The company successfully delivered 1440 mm2 large-section heat-resistant aluminum alloy wire JNRLH60/G1A-1440/120 for a power user in Guangxi. It indicates that Chinese manufacturers have the ability to stably provide large cross-section heat-resistant wire products.
At the end of February 2006, Shanghai Zhongtian Aluminum Wire Co., Ltd. received a call from a power user in Guangxi asking if it could urgently produce a large cross-section heat-resistant aluminum alloy wire of 1440 mm2 for substation power lines. And the time requirement is to supply it within one week of signing the contract. Upon receiving this information, Shanghai Zhongtian Aluminum Wire Co., Ltd. immediately convened an emergency meeting of the departments of production, technology, quality and logistics to study the feasibility of its supply. After analysis, this kind of wire is a special technical wire with high technical content. It is difficult to produce. There is no production record for Zhongtian Aluminum wire in the past. At present, there is basically no factory capable of production, but the key technology is solved and the maturity and production are With regard to equipment configuration, process, production, and quality control capabilities, the company already has the ability to produce 1440 mm2 large-section, 60% IACS heat-resistant aluminum alloy wires. At the same time, the company is providing 60% IACS heat-resistant aluminum alloy wire to meet the 2008 Beijing Olympics power grid renovation project, has accumulated a lot of experience. Taking into account the special circumstances, although the company's own production tasks are very heavy, in order to solve the urgent needs of users, the company decided to undertake the project.
After the signing of the contract, the company organized a special project emergency team, and after intense joint research, some technical problems that may arise in the production of this type of large-section, heat-resistant wire, through adjustment of process parameters, stranding equipment and molds, and improvement The detection method and frequency form a careful production plan. Through the special project emergency team and the staff's efforts, we have finally produced products that meet the technical requirements. After strict inspection, all the indicators of the products meet the design requirements and are delivered to users within the specified time. The users stated that Shanghai Zhongtian Aluminum Wire, as the mainstream manufacturer of the company's basic positioning for producing special wires, is a service that people really have to admire.
Shanghai Zhongtian Aluminum Wire Co., Ltd. succeeded in developing the heat-resistant aluminum alloy and high-strength heat-resistant aluminum alloy with 60% conductivity last year after successfully passing the product appraisal and technical appraisal jointly organized by the Shanghai Science and Technology Commission and the Shanghai Economic Commission. 1440mm2 large section wire, and successfully delivered to the user. The successful production of this wire represents that Shanghai Zhongtian Aluminum Wire Co., Ltd. has become one of the few domestic wire manufacturers that can produce 1440 mm2.
