We have a huge annual production capacity of more than 1.8million strings of 110kV composite insulators, which provides strong support for the requirement of the customer. We integrated the international and domestic advantaged technology to develop full range of composite insulators with 10 kV ~1000 kV AC, ±110kV~±1100kV DC voltage and 40kN ~1000kN mechanical strength, as well as various composite insulators in electrical railway contact networks.
There are 42 full-automatic injection molding machines and 9 crimping machines including 8000kN ones imported from Germany. 9 test labs subordinate to testing center, of which the high-voltage test room equipped with 1000kV power frequency test transformer and complete-set 1800kV steep front impulse voltage test equipment; the mechanical test room is equipped with 3000kN tension tester at the most.
It is a member company of Standardization Administration of People’s Republic of China and Standardization Administration in electric power industry. As one of the markers of national and industrial standards, it has taken part in the formulation of national and industrial standard for composite insulator for a long time.
It is the supplier of over 50% shares of composite insulators of the Yunnan-Guangdong diret current project which is the world first circuit with the highest voltage ±800kV.
It is the only composite insulator company in the world that has successfully set power grids in the area with the highest altitude (4300 meters) and operated for 20 years, making great contribution to the aging research in an environment at a high altitude and with strong ultraviolet exposure for China’s composite insulator industry.
It is the only enterprise that has studied natural aging (exposure test) of rubber ingredients in nine different climate conditions for 10 years and has stuck to research on improvement of the property of rubber ingredients, rods, hardware fittings and interface, making it a pioneer in the industry.
