Product Description

Integrated control system for wind, solar, and energy storage
A subsidiary of Chengming Metal Technology (Shandong) Co., Ltd. is a national high-tech enterprise focused on the development and utilization of new energy. The new energy development investment platform, Sunshine New Energy, focuses on the fields of photovoltaic, wind power, wind and solar energy storage, hydrogen charging, and multi energy integration, providing comprehensive solutions covering the entire lifecycle of new energy development, including system research and development, development investment, design and construction, and operation management. It is the world's largest developer of photovoltaic power stations.

As a leader in the field of new energy system technology, the company was one of the earliest to establish a new energy system technology research and development center in the industry, creating a unique PowMart smart energy solution group, constructing three core technology systems of "efficient power generation, system integration, and full life cycle optimization of power stations", leading the formulation of multiple industry standards, and possessing strong independent research and innovation capabilities.

We are a leading one-stop solution provider for distributed photovoltaic power station systems in China, dedicated to professional production factories in the research and development, production, and testing of photovoltaic module products. And it is a comprehensive service provider that integrates research and development of new energy products, investment in power stations, production, sales, design, installation, grid connection, and operation and maintenance, from photovoltaic products to intelligent solutions. It is the first one-stop centralized procurement and operation center for photovoltaic power stations. The company has multiple TUV certified intelligent automated photovoltaic module production lines.

This includes suppliers of photovoltaic module materials (Longi, JA, Jinko, Tongwei, Huawei, Sunshine, etc.), production equipment manufacturers, and terminal sales service providers, covering countries such as Southeast Asia, Europe and America, South America, and Africa. With the joint participation of professional elites and sectors, the entire industry forms complementarity, multi chain collaboration, highly concentrated industrial chains, and rapidly soaring industrial scale and quality, constantly innovating and leading industry progress.

In the future, Sunshine New Energy will uphold the mission of "allowing everyone to enjoy clean electricity", based on the vision of "becoming a global leader in new energy generation technology", deeply cultivate the field of new energy development, continue to promote technological progress in new energy systems, become a leading practitioner in building a new type of power system with new energy as the main body, provide economically efficient and sustainable new energy solutions for society, and strive to build the company into a world-class new energy enterprise. We are a professional team company that integrates the research and development, design, and construction of wind and solar energy storage intelligent integrated systems. Our design scope includes wind power generation systems, high and low voltage switchgear, automation devices, frequency converter control cabinets, boiler operation consoles, power distribution cabinets, equipment covers, stainless steel cabinet manufacturing, low-voltage distribution cabinets, frequency converter and soft start control cabinets, boiler operation consoles, and PLC automation integration. We provide customers with one-stop services, and various system solutions vary according to different building structures and user power generation demands. We provide effective solar energy comprehensive solutions for residential areas, hotels, schools, hospitals, factories, and agricultural fields. Provide project consulting, design, construction and other services to clients.



High-voltage switchgear is a crucial component of electrical power systems, used for switching, controlling, or protecting functions during power generation, transmission, distribution, and energy conversion. The voltage levels for high-voltage switchgear typically range from 3.6kV to 550kV.
High-voltage switchgear is a crucial component of electrical power systems, used for switching, controlling, or protecting functions during power generation, transmission, distribution, and energy conversion. The voltage levels for high-voltage switchgear typically range from 3.6kV to 550kV.



Key equipment within high-voltage switchgear includes high-voltage circuit breakers, isolators and earth switches, load switches, automatic reclosers and sectionalizes, as well as operating mechanisms. Additionally, high-voltage switchgear should have "five preventions" functions, which are safety measures to prevent incorrect closing or opening of the circuit breaker, closing with ground wire attached, entering live compartments by mistake, attaching ground wire while live, and pulling load break switches with load.

Environment condition

1.Temperature of ambient air: -5°C~+40°C; The average daily temperature shall not be higher than +35°C. In case of excess, the capacity shall be reduced according to the actual situation. 2.Altitude: ≤ 2000m. 3.relative humidity: the maximum temperature of +40°C is not more than 50%, at a lower temperature allowed to have a large relative humidity: such as +20°C is 90%, should take into account the temperature changes may occasionally produce the impact of condensation. 4.The mounting incline shall not exceed 5. and the whole group of cabinets is relatively flat (in line with GBJ232-82 standard). 5.Switchgear should be installed in places free from severe vibration and shock and not enough to cause undue corrosion of electrical components.
