After the on-site review by the expert team of the National Accreditation Commission and the review and acceptance of the rectification project, the Nanjing Electric Testing Center recently passed the national laboratory recertification review and obtained the new CNAS laboratory accreditation certificate issued by the China National Accreditation Service for Conformity Assessment.

The testing center (laboratory) of Nanjing Electric (Group) Co., Ltd. passed the laboratory accreditation of the China National Accreditation Service for Conformity Assessment in 2009 and obtained the accreditation certificate issued by the National Accreditation Service. From June 3 to 4, 2017, the National Accreditation Commission expert team came to the company to conduct a three-year renewal review of the national laboratory-the company's testing center. The two experts of the expert group conducted a serious, responsible, rigorous and meticulous on-site audit of the testing scope and capabilities of the testing center of Nanjing Electric Technology Co., Ltd. in the new plant area of ​​Xianxin East Road, Nanjing. Type insulators, composite insulators, AC transformers and other products have been verified and assessed for product testing capabilities, and the quality management system of the testing center has been reviewed in accordance with the "Laboratory Qualification Evaluation Criteria". The review experts made a fair and objective evaluation of the company's testing center quality management system and testing capabilities. While affirming the work results, they also put forward relevant rectification requirements. After completing the rectification on schedule and after review and acceptance, the company obtained a new national laboratory accreditation certificate on August 23, 2017.

According to Fan Jianer, director of the company’s testing center, the company’s testing center currently mainly meets the needs of national UHV projects, urban and rural power grid construction, and undertakes quality control, new material testing, product development and product appraisal testing during the production process of power products, and Product installation, repair, transformation and other quality inspection work. The business scope includes high-voltage line porcelain or glass insulator strings, string sets and their components, high-voltage pillar insulators, oil-impregnated, glue-impregnated and dry-type high-voltage bushings, high-voltage insulators, high-voltage current transformers, voltage transformers and other high-voltage electrical equipment, AC Rod-shaped suspension composite insulators for overhead lines and other products. The AC voltage level ranges from 1000V to 1000kV UHV, and the DC voltage level ranges from ±1000V to ±1100kV UHV.

In order to implement the national “One Belt One Road” strategic policy, the laboratory has established friendly cooperation with state key laboratories such as the China Electric Power Research Institute, as well as internationally renowned and authoritative experimental research institutions-KEMA laboratory, Cairo University and other units. The international market, especially the Asian and African markets, have requirements for power products, and extensive international cooperation has been carried out to conduct experimental research on various products.

In order to meet the needs of national and international power development, the company built a UHV shielding laboratory (73 meters * 40 meters * 40 meters) in the new area of ​​Nanjing Electric Science and Technology Industrial Park, Xianxin East Road, and added 1500kV test transformers, 1500V standard capacitors, and 4400kV shocks. Voltage measurement system, upgradeable ±2400kV/30mA DC test equipment, digital partial discharge meter, capacitor bridge and other equipment; newly added 1000kN heat engine, 1000kN tension machine and other major equipment; composite insulator laboratory (48m*38m* 22.6 meters), add major test equipment such as 500kV AC and DC test transformers. The laboratory area in the new area is more than 10,000 square meters and more than 100 new test equipments have been added. With high and low voltage insulators, high and low voltage electrical appliances, power transmission and transformation equipment and other product inspection conditions, it is currently one of the domestic laboratories with the most complete test equipment and the highest test voltage level.

According to the needs of national power construction and enterprise development, the company will strengthen the training and introduction of testing talents, further improve the level of testing technology, and better meet the needs of high and low voltage technology research and engineering construction at home and abroad.
