China composite insulator manufacturer
Xiangyang Guowang Composite Insulators Co., Ltd. (Formerly known as Xiangfan Guowang Composite Insulators Co., Ltd.)，who is top manufacturer for silicone rubber polymer long rod insulator and composite post insulator， was located in High & New Tech Park of Xiangyang City (Formerly name is Xiangfan City). She was established in 1988 while the company name was Xiangfan Electric Power Equipment Plant, and in 1997, the company was incorporated and registered as Xiangfan Guowang Composite Insulators Co., Ltd. In 2012, the company was merged in Nari Group Corporation.
In the early 1980’s, the company has taken the lead in researching and developing composite insulators in China, and introduced her series products of TONLY™ composite insulators to utilities. All its products for various voltage applications were firstly passing tests and accredited with national level in China, and its 500kV AC and DC, 800kV DC and 1000kV AC composite insulators were firstly served in the power grid of China.

Sheds and sheath of polymer insulator
The Sheds and sheath is the outer insulating part of the composite insulator. Its function is to make the composite insulator have sufficiently high external insulation performance against moisture flashover and pollution flashover to protect the core rod from the external atmosphere... more details >>
PROJECTS
Changji-Guquan ±1100 kV UHV project(China)
Changji-Guquan ultra high voltage(UHV) Power Transmission Line applied a voltage of ±1100 kV, which is highest voltage in the world. Also it has the largest transmission capacity and fastest transmission distance.
India 500kV power transmission line
The Southwest Inter-tie transmission Project (SWIP) applied 500 kV silicon suspension insulators from White Pine Generating Station to the Midpoint substation in south central Idaho.
Kenya 400kV power grid
Loiyangalani-Suswa 400KV Transmission Line Project apllied composite insulators with a voltage of 400 kV manufactured by GW, and proved to have a reliable quality during these years of operation.
Three Gorges (Sanxia) Dam
Three Gorges (Sanxia) is the top 1 hydropower station in the world. China’s largest construction project since the Great Wall and the biggest dam in the world in terms of installed capacity. After used composite insulators, the flashover accidents decliend much less.
The Baihetan Dam (China)
