Glass insulator is a special insulation component used in overhead transmission lines to provide insulation and support for wires.
Jiangxi Huayao Electric Co., Ltd., which is located in Shangbu Town Industrial Park, Luxi County, Pingxiang City, Jiangxi Province,China is one of the leading glass insulator manufacturers in China. The registered capital of the company is 120 million yuan, covering an area of 47 acres, with a total construction area of 17200 square meters and more than 150 employees.
Huayao advantage products are glass insulators with a capacity of 40kN-550kN, which can meet the requirements of 10kV-500kV ultra-high voltage and extra high voltage transmission and transformation lines.
Huayao control the quality starting from the careful screening of raw materials and automatic batching, every link follows a strict technological process, from melting to pressing, from uniform tempering to cold and hot impact, homogenization treatment, to subsequent gluing, maintenance, inspection and packaging, until the final product leaves the factory.
Structural composition:
The product consists of an iron cap, tempered glass parts, and steel feet, and is integrated with cement adhesive. This product adopts the most advanced cylindrical head structure internationally, characterized by small head size, light weight, high strength, and large creepage distance. Can save metal materials and reduce line costs. To meet the needs of live working, traditional domestic structural shapes are used on the brim of the hat.
Main types of glass insulator
Glass insulator is including standard type, pollution resistant type, DC type, spherical type, aerodynamic type, ground wire type, and contact network for electrified railways.
Jiangxi Huayao electric Co.,ltd produce standard type glass insulator 40-550Kn, Pollution resistant type 70-400Kn, mutil-umbrella type 120-330kN, Glass insulator aerodynamic type 120-300kN, ground wire type.
