Recently, Nanjing Testing Center passes CNAS laboratory renewals of certificate review with examine site and reviewing the acceptance by panel of CNAS, and obtains Laboratory accreditation certificate of CNAS laboratory by China National Accreditation Service for Conformity Assessment.

    Nanjing Electric (Group) co., LTD. Testing Center (lab) in 2009 by the Accrediting Commission for Conformity Assessment in China national laboratory accreditation, obtain approval certificates issued by CNACL.

    From June 3 to June 4, 2017, the group of experts from the National Accreditation Committee came to the company to conduct a three-year renewal review of the state-level laboratory-company testing center.

    The two experts of the expert group conducted a serious, responsible, rigorous and detailed on-site audit on the testing scope and capability of the testing center of Nanjing Electric Technology Co., Ltd. in the new plant of Nanjing Xinxindong Road. Insulators, composite insulators, AC transformers and other products for product testing capability verification and assessment of the test center quality management system according to "laboratory accreditation criteria review" were reviewed.

    Evaluation experts on the company's testing center quality management system and testing capabilities to make a fair and objective evaluation, while affirming the performance, but also made the rectification requirements. After completing the rectification on schedule and passing the examination and acceptance, the Company obtained the new national laboratory accreditation certificate on August 23, 2017.

    According to Fan Jianer, director of the company's testing center, the testing center of the company currently mainly meets the needs of national UHV construction, urban and rural power grid construction, and undertakes the quality control, new material testing, product development and product qualification testing during the production of power products. Product installation, repair, alteration and other quality inspection work. Lines of business include high-voltage line porcelain or glass insulator string, string and its components, high-voltage pillar insulators, oil immersion, plastic dip and dry high voltage bushing, high voltage insulators, high voltage current transformer, voltage transformer and other high voltage electrical equipment, exchange Overhead lines with rod suspension composite insulators and other products.

    AC voltage levels from 1000V to 1000kV UHV, DC voltage levels from ± 1000V to ± 1100kV UHV .In order to implement the national "One Belt and One Road" strategy, the laboratory has conducted friendly cooperation with such key laboratories as the China Electric Power Research Institute and other internationally acclaimed authoritative experimental research institutes, such as KEMA Laboratory and Cairo University. In the international market, especially in Asia and Africa, we have conducted extensive international cooperation and carried out experimental research on various types of products.

    To meet the needs of national and international power development, the company built a UHV shielding laboratory (73m * 40m * 40m) in Nanjing New Electric Technology Industrial Park, Xianxin East Road, adding 1500kV test transformer, 1500V standard capacitor and 4400kV impact Voltage measurement system, upgradeable ± 2400kV / 30mA DC test equipment, digital partial discharge meter, capacitor bridge and other equipment and instruments; new 1000kN heat machine, 1000kN Rally machine and other major equipment; composite insulator laboratory (48 m * 38 m * 22.6 meters), adding 500kV AC and DC test transformers and other major test equipment. The new laboratory area of over 10,000 square meters, more than 100 new test equipment. With high and low voltage insulators, high and low voltage electrical appliances, power transmission equipment and other product testing conditions, is currently the most complete test equipment, the highest test voltage one of the laboratories.

    According to the national power construction and enterprise development needs, the company will strengthen the training of testing personnel, the introduction of further improve the detection technology to better meet the domestic and foreign high and low voltage technology research and construction needs.
