420kN insulators U420B stain-resistant Suspension Electrical Glass Insulator

420kN stain-resistant disc suspension glass insulator U420BP 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. 
Huayao's glass insulators and electrical equipment can withstand the test of various complex environments, operate stably and reliably, and show strong adaptability and excellent performance. Whether in hot and rainy tropical areas, desert areas with harsh climate, or mountainous areas with complex terrain.

Compared with other types of insulators, such as ceramic insulators, tempered glass insulators have the following main advantages:

1. High mechanical strength: Tempered glass insulators can withstand greater tension and pressure, which makes them more reliable in applications such as high-voltage power lines.
2. Good pollution resistance: The surface of the glass material is not easy to accumulate pollution, which reduces the flashover accident caused by pollution and improves the safety of the power system.
3. The self-explosion rate is relatively low: When the tempered glass insulator fails during use, it often shows self-explosion. This failure mode is easy to be found and located, which is conducive to timely maintenance and replacement.
4. The production process is relatively simple: The production process of tempered glass insulators is relatively simple, which helps to reduce costs and improve production efficiency.
5. Beautiful appearance: Tempered glass insulators are usually transparent or translucent, and the appearance is beautiful and generous, which to a certain extent enhances the overall image of power facilities.

The Production process flow:

The production process of glass insulators in Jiangxi Huayao Electric Co.,Ltd is as follows:
Mix raw material=>melt glass liquid=>press to glass insulator shape=> tempering treatment=>cold and shock test=> Glue assembly=> routine test and other test=> Finished products package.
