Dongguan Gaoneng Electric Co., Ltd.

Dongguan Gaoneng Electric Co., Ltd., a high tech enterprise established in 1994, specializes in the manufacture of composite insulators for electric power and electrified railways. Through 17 years development, our company has been developing into one of the largest composite insulator manufacturers in China and the sales value for 2010 was about RMB 290 million (USD42 million).
The products cover 10kV/70kN to 1,000kV/530kN AC and 500kV 660KV, 800kV and 1000KV DC composite insulators , also including differnt lever composite insulators for electrified railways.
Upto December 2010, over 4 million pieces of composite insulators have been in operation in china and abroad. Of the 4.3 million pieces insulators, over 250,000 pieces are extra-high voltage composite insulators (500kV and above), which make us the No.1 in China and even in the world in this term. We have supplied our insulators for almost all national key projects of electric power transmission of China such as Three Gorge Project, d.c. power transmission projects and power grid inter-connecting project etc. State Grid Co. of China is now constructing its 1000kV transmission line which will be the first 1000kV transmission line for commercial operation worldwide. In 2007, our company won 2 of the 4 packages for the 1000kV composite insulators which amounted to 3600 pieces. In addition, we have supplied over 4500 pieces of 800kV d.c. composite insulators to China Southern Power Grid, which is now building the first 800kV d.c. transmission line of the world. In 2007, we supplied 2080 pieces of 750kV composite insulators to State Grid Co. of China for its exampling project.
Our company was also the first company whose composite insulators were used for electrified railways in China as earlier as 1998. There are now over 160,000 pieces of insulators operating on electrified railways across China.
Our company has always attached great importance to the research and development of composite insulators. Besides the normal type tests on the 10kV to 1000kV a.c and 500kV and 800kV d.c. insulators, we have also done lots of other research tests, including 5000 hours ageing test at KEMA lab, pollutant accumulation tests, electric field distribution tests, ice-covering tests, accelerated weathering tests, salt fog pollution withstand tests, long-term mechanical performance tests, hydrophobicity recovery tests, bonding between core rod and rubber tests, and high-pressure washing test etc.
Particularly worth mentioning is that in 2005 we conducted pollution withstand test under full voltage (826kV d.c) on our 800kV d.c composite insulators of full length (about 8750mm) at STRI lab in Sweden, which was the first and the only test even in the world as of today. Through this test we got the fundamental dimensions for 800kV insulators such as creepage distance, arc distance and weather shed profile etc. This test also provided some important data and information for the design of the first 800kV d.c. transmission line in China, of which the construction is under way.
The inspection centre of our company has been furnished with complete inspecting and testing facilities such as 3,600kV steep wave impulse voltage generator, 1,500kV power frequency testing facility, 15mx2200kN tension load machine, 25kNx5m bending and torsional testing machine and a well-equipped physical and chemical test laboratory etc. We have strict quality-monitoring and inspection procedures for manufacturing process and for final products, and our company has been strictly implementing and maintaining a quality management system of ISO 9001 since 1998.
Our products have now been exported to over 20 countries covering Europe, America, Africa, Asia and Australia. In 2007 we supplied nearly 14,000 pieces of 400kV composite insulators to Power Grid Co. of India Ltd, which was the first time that composite insulators were used on extra-high voltage transmission line in India.
