QINGDAO COSINE Electrical Equipment specializes in supplying various kinds of insulator and pole line hardware. With high speed of power construction in China and oversea country, QINGDAO COSINE has grown into a leader of exporting of insulator in China.
Our products range from10KV-500KV polymer insulator, 40KN-420KN porcelain insulator and various kinds of pole line hardware. All the insulators have been produced by modern equipment, For example,500KV polymer insulator has been produced by high volume injection machine, which can finish two pieces 500KV at one time. Mention to the porcelain insulator, the vacuum pug mill has been imported from Germany in order to control the quality from blank.
