In recent years, we have applied test certification from recognized certification authorities from home and abroad, such as National Quality Supervision and Testing Center for Cable and Wire, Quality Inspection and Test Center for Equipment of Electric Power (Wuhan) and so on. We have got the type test report and 

220kV pre-identification test report from KEMA (We have passed the type test for 1kV, 10kV, 35kV, 110kV and 220kV grade). Also, we have got the ISO9001 Quality Management Certification, ISO14001 Environment Management Certification and OHSAS18001 Occupational Health and Safety Management Certification.

With the optimization and improvement of our cable accessories, we also become a studying team which will promote talent development and cultivate our employees as a high qualified team. We have developed five new types of power transmission and distribution products in two series and applied 31 patents. Our 

110kV cable terminal for 2500mm2 has filled the international gap and contributed for peak carbon dioxide emissions of high energy-consumption enterprise. Our 1kV~110kV cable accessories have passed qualification and sales performance certificate, prequalification of State Grid, and become a core supplier.
