Time tempers craftsmanship, and standards define an industry. Coinciding with the milestone of Kunming Cable Group's 90th anniversary, the Technical Specification for Construction Quality and Acceptance of Building-Integrated Distributed Photovoltaic Engineering in Yunnan Province (DBJ 53/T-187-2025), approved and released by the Department of Housing and Urban-Rural Development of Yunnan Province, was officially finalized and came into full effect on April 1, 2026.
As a core contributing unit, Kunming Cable Group's Kungong Electric Cable Co., Ltd. participated deeply in the entire compilation process. Two key experts from the Group—Chief Engineer Xi Youjian and Deputy General Manager of the New Energy Company, Hui Shuhua—were listed among the principal drafters of the specification, leveraging their professional expertise to set rules, define benchmarks, and establish bottom lines for building-integrated PV engineering in Yunnan.
From ninety years of deep cultivation in the wire and cable industry to a concentrated push into the green energy, Kunming Cable Group Co., Ltd. has always stayed true to its original aspiration as "the cradle of China's wire and cable industry," focusing on three major tracks: standard leadership, technological innovation, and industrial synergy. Kungong Electric Cable, with its expertise in cable R&D and manufacturing, has embedded its electrical engineering know-how into core provisions of the specification—covering PV cable selection, laying, and grounding—thereby solidifying the electrical safety foundation of PV projects. Meanwhile, Kunming Cable Group New Energy Co., Ltd., rooted in the frontlines of PV EPC contracting, project construction, and on-site acceptance, has translated years of hands-on experience into regulatory clauses, filling the gap in provincial standards for building PV construction and acceptance.
One expert has dedicated himself to cable technology; the other to PV engineering. One upholds the foundation of industrial manufacturing; the other rides the tide of green energy. Together, they have co-authored the specification, pooling their wisdom—a testament not only to their individual professional caliber but also to the tripartite synergy of Kunming Cable Group, Kungong Electric Cable, and the New Energy Company.
Ninety years of glory, a legacy passed down; sailing with standards as the canvas, steering towards green energy. This collaboration in drafting a provincial-level technical specification is a resounding testament to Kunming Cable Group's 90-year heritage of craftsmanship—and a reflection of its commitment to empowering the dual-carbon goals, driving standardized development in the PV industry, and serving as a responsible leader rooted in Yunnan. Looking ahead, the Group will continue to be guided by standards innovation, supported by technical talent, and integrated across the full industrial chain of cable manufacturing, PV engineering, and green energy, writing a new chapter for a century-old Kunming Cable in the wave of the new-era energy transition.
