ADVANCED TEST FACILITY
Laboratory Name: Nanjing Electric (Group) Co., Ltd. Testing Center
The testing center of Nanjing Electric (Group) Co., Ltd. was established in April 2009. In September 2019, it passed the review at the new manufacturing base of Nanjing Electric Technology Co., Ltd. located in the national high-tech development zone. It is mainly responsible for the quality of the product production process. Control, new material testing, product development and product identification testing, as well as product installation, repair, transformation and other quality inspections. In 2016, a new laboratory base was built in Xingang Development Zone, and we are currently discussing cooperation matters with KEMA laboratory.
Business scope: high-voltage line porcelain or glass insulator strings, strings and their components, high-voltage pillar insulators, high-voltage bushings, high-voltage insulators, high-voltage isolation switches and grounding switches, current transformers, voltage transformers and other high-voltage electrical equipment, AC overhead lines 8 series of rod-shaped suspension composite insulators. The product test AC voltage level ranges from 1kV to UHV 1200kV, and the DC voltage level ranges from ±10kV to ±2400kV.
The laboratory currently has 23 personnel, including 8 engineering and technical personnel, with fixed assets of 29.8 million yuan, a total construction area of 10,317 square meters, and 105 main inspection equipment. It is currently the most complete test equipment and the highest test voltage in East China. One of the high-pressure laboratories.
