The year of 2025 is a year of harvest. Chongqing South Flameproof Wire and Cable Co., Ltd., by virtue of excellent product quality and all-round service, has successfully won the bidding for the supply project of various types of wires and cables of RMB 50 million by the Project Department of 28 Work Area of Phase I Project of Jinan Rail Transit Line 4 of China Railway 15th Bureau Group Co., Ltd., and won the title of "Excellent Cooperative Supplier". It has become a model of "Quality+Service" double benchmark in the field of rail transit construction.
As a national high-tech enterprise, NANFANGZURAN cable industry has been under cultivation for 27 years, and a whole-process quality control system from R&D to testing has been established. With high-precision oxygen-free copper as the core conductor, the product has passed 5000+times of eccentricity and insulation resistance tests, with excellent conductivity and low resistance, meeting the simultaneous operation requirements of multiple high-power equipment. In view of the rail transit scene, the environmental protection flame-retardant cable independently developed by the enterprise adopts halogen-free insulation material, which is non-toxic and free of smoke and corrosive gas during combustion. The carbonization length is strictly controlled within 2500mm, which conforms to the national flame-retardant standard and provides a key guarantee for the safe escape of passengers.

More than 20 types of products supplied this time, including power cables, fireproof cables and intelligent cables, have passed the ISO three management system certification and 3C compulsory certification, and the technical indicators have reached the domestic leading level. During the implementation of the Project, the Company established a special service team to track the whole process from demand docking, production scheduling to logistics distribution. In view of the characteristics of tight construction period and high technical requirements of Jinan Rail Transit Line 4, the enterprise shall complete the capacity allocation 30 days in advance, and dispatch technical personnel to the site for support, so as to ensure that the 12 types of customized cables are delivered on time. The "7 × 24 hour emergency response mechanism" was highly evaluated by the Project Department: in the critical period of shield section construction, the enterprise completed the emergency supplement order within 48 hours to ensure the project progress.
The cooperation is that after serving Guangzhou Metro, Southern Flame Retardant has again won the order of national rail transit project. At present, the Company has more than 650 sales agents nationwide, and the products are widely used in electric power, construction, metallurgy and other fields, with a total of 120 patents and 103 national construction methods. The project leader of China Railway 15th Bureau Group Co., Ltd. said: "With the delivery standard of" zero defect "and the service response of" zero delay ", Southern Flame Retardant has set a new benchmark for the supply chain cooperation of major projects." In the future, Southern Flame Retardant will continue to deepen the concept of "science and technology first, quality oriented", and provide a better cable solution for national infrastructure construction such as rail transit with innovation-driven development.
