In a recent news article written by Liuyang, Linan, Dalian Insulator Co. was featured as having developed internally and manufactured insulators for a 1000KV transmission project. The South Jindong – Nanyang – Jinmeng Super High Voltage A.C. test project was put into operation. Our country reached its peak of international high voltage transmission technology! Since Dalian Insulator products were used on this project, the State Grid Authority sent a special acknowledgement letter stating “the important role played by Dalian Insulator Co. in the self-development, innovation and domestication of this project.” This high voltage insulator was a great contribution to the self-sufficiency of China’s insulator industry, reducing costs and breaking the overseas monopoly in these products.
Dalian Insulator Co. develops and manufactures super high voltage and high strength suspension insulators which is an important part of the 1000KV transmission heavy equipment construction projects during the eleventh “Five Year Plan.” In 2006, Dalian Insulator Co. Ltd. developed Super High Voltage 420kN double and triple disc and 550kN single disc type suspension insulators which have been approved by the authorities at the China Electric Enterprise Union.
The Authorities agree that the three products reach international standards in their technology parameters and specifications, two of which filled domestic gaps and one filling global gaps.
In the last five years, Dalian Insulator Co. Ltd has further improved its Super High Voltage product range which has laid the foundation for the construction of National one million volt A.C. & D.C. transmission lines and introducing new products into both the domestic and overseas markets. For its next step, Dalian Insulator Co. will fulfill its new plans with development projects for static power station Static Power Stations, Pole Line Hardware, Transformers and Surge Arrestersto expand the company’s product range.
