The newly completed high-temperature vulcanized silicone rubber workshop in Xinjin Base of Bluestar Chengrand Institute recently embraced a customer delegation composed of Siemens (China) Surge Arrester Company, and Siemens (Germany) Headquarters sales representatives and its customer TD HV Consult Company (Canada) representatives to review its quality control system and production process.

Because of the particularity of the power industry, customers require that the qualified rate of products must reach 100 percent to ensure the continuous and stable operation of the power system of downstream customers. German customers have always been famous for their strict professionalism. They have put forward specific requirements for the quality management system of Bluestar Chengrand Institute: products should have perfect quality control plans, product traceability, and advanced on-site management; and the product production and management process and quality control process should reach or even surpass the level of its foreign counterparts.

During the audit in the high-temperature glue workshop, the delegation consulted a series of process documents and conducted a production site audit. By reviewing the key quality control points and the inspection process of raw materials, intermediate products, and finished products in the production process of the division, the whole process of finished product inspection is strictly followed, fully affirming the quality system of Bluestar Chengrand Institute. The delegation agreed that the quality control and on-site management of the high-temperature glue division are effective and controllable, and the products are trustworthy, clearly expressing its intention for further cooperation. “Chengrand Manufacturing” is once again recognized by international high-end customers.

Siemens Surge Arrester Company mainly produces medium-voltage silica gel insulated surge arresters, insulators, and cage surge arresters. With its profound technical strength and brand influence, the products are favored by high-end customers and occupy a large share in the market of high-end surge arresters and insulators. It is reputed as a benchmark enterprise in the international power industry. After passing the quality audit of Siemens, Bluestar Chengrand Institute not only won an important customer in the international market but also will have a positive demonstration effect, bringing new opportunities for the focused development of silicone business in the power and electric market and further expansion of the international market.

Silicone rubber products produced by Bluestar Chengrand Institute have entered China's power transmission and distribution equipment market since the 1990s and gradually formed a silicone rubber product system with completely independent intellectual property rights and an in-store industry, covering a series of products from liquid silicone rubber to high-temperature vulcanized silicone rubber. Currently, the company has become an advanced supplier and technology leader of silicone rubber products in the domestic power industry and represented an important material-supporting enterprise for the development and export of UHV transmission technology in China.
