"Three Old and Two New"
The "Three Firsts and Two New" recognition system in Jiangsu Province serves as a pivotal policy tool for advancing the research, development, and application of new technologies and products within the province. Its primary objective is to motivate enterprises to make breakthroughs in key core technologies and expedite the commercialization of their research outcomes. Specifically, the "Three Firsts" encompass the first set of equipment, the first batch of new materials, and the first version of software. Notably, the first set of equipment refers to high-end equipment that fills a domestic or provincial gap. The "Two New" refers to new technologies and products, excluding those covered by the "Three Firsts," that exhibit innovation and possess market potential.

In recent years, driven by both market forces and policies, the new energy industry has experienced explosive growth, leading to an increasing demand for system voltage. Coupled with the challenging operational environment, this poses unprecedentedly stringent challenges to the performance of circuit breakers. The contradiction between high specifications and low costs, emphasis on research and development and rapid iteration, as well as the tension between high power and miniaturization, has become a persistent bottleneck hindering the development of the new energy industry.
To address the pain points in the new energy industry, the Changshu Switchgear R&D team has successfully developed the "CM6S-400, 630HU, CM6SDC-400, 630HU, CM6SDC-400, 630HHU plastic case circuit breakers" and "CW3MGDC-1600HU/2 DC disconnectors" after multiple trial productions and rigorous experiments. The successful inclusion of these products in Jiangsu Province's 2025 "Three Firsts and Two New" Proposed Technical Product List is undoubtedly an authoritative certification of Changshu Switchgear's innovation capabilities and market applications.

As a pioneer in the domestic low-voltage electrical apparatus field, Changshu Switchgear has leveraged over 50 years of technological accumulation to establish a product matrix encompassing components, complete cabinets, and systems. These products are widely utilized in various sectors, including industry, electricity, machinery, transportation, petrochemicals, construction, nuclear power, and new energy. Owing to their stable quality and excellent performance, Changshu Switchgear has consistently made breakthroughs in the high-end market.
Facing the future, Changshu Switchgear will take its inclusion in the "Three Firsts and Two New" as an opportunity to continue adhering to the development direction of "specialization, refinement, uniqueness, and innovation". It will further enhance its research and application capabilities in key technologies, boldly lead the way, and fully contribute to the innovative development of the low-voltage electrical equipment industry.
