Product introduction
MOV is the core element of metal oxide arrester. Its performance directly determines the performance of arrester. Based on the quality management policy of ”quality first, pursuit of excellence”, GCEC has been making continuous technical improvement, equipment introduction and process improvement since the production of MOV in 1994. At present, the production capacity of MOV and quality are at the leading level in China.
1.Production capacity of MOV: The diameter of MOV produced is 28 ~136mm, and about 8 million pieces of MOV were produced every year.
2.Quality assurance: GCEC uses increasingly perfect quality management system to control MOV.
3.Standard: according to IEC60099-4.
