Great Wall Central Asia Electrical Appliance Co., Ltd.

Since our company was founded in ***5, our company covers a total area of about 3,**0 square meters and 2,**0 square meters of production area, and continues to contribute to the field of electrical contacts in China. As an elite in the manufacture of electrical contacts, our company has nearly *0 years of rich experience in the production of high-voltage switch contacts. In terms of new product development and process improvement and innovation, our company is always at the forefront of the industry, leading the development trend of copper- and tungsten-based medium- and high-voltage contact technology. Its main products - tungsten-based contacts, copper-based contacts, silver-based contacts and other products of powder metallurgy - are widely favored by the fields of power transmission and transformation equipment, national defense and military industry, aerospace and nuclear power due to their excellent wear-resisting, heat-resisting and corrosion-resisting properties. The company also provides a large number of high-quality and highly reliable contacts for domestic and foreign high-voltage and super (special) power products from *0Kv to ***0kV, making outstanding contributions to the development of China's electric power industry. In terms of production technology, the company is equipped with two specialized production workshops for powder metallurgy and finishing, with more than *0 sets of advanced production and testing equipment. Through the introduction of CNC machine tools to replace the traditional machine tools, as well as vertical sintering and other advanced technologies to innovate the traditional process, the company has comprehensively enhanced the level of specialized digital equipment, significantly improving the production efficiency and quality of products. The application of advanced technologies such as high-frequency welding, laser welding, etc. has significantly reduced the material cost and scrap rate, providing better guarantee for the quality of the company's products. After nearly *0 years of development, the company's products have been widely used in the country's major power engineering projects. From ***0kV extra-high voltage AC transmission projects to ±***0kV DC transmission projects, to **0kV and **0kV ultra-high voltage AC transmission projects, etc., our electrical contact products have won wide recognition in the market for their excellent performance and stability, durability, and so on. Looking ahead, our company will continue to make in-depth layout in tungsten-based, copper-based and silver-based industries, and deeply plow into the metal alloy smelting industry and high-voltage contact field. The company will devote itself to the research of advanced copper-tungsten powder metallurgy process, the application of new copper-tungsten contact materials and other metal alloy smelting technologies, to provide customers with more excellent solutions, and to promote China's electrical contact industry to a new peak.
