SYGG's glass inaulators so far has the best shattering rate in the industry with its digitally control glass roughening manufacturering process. There are more than 30 millions of SYGG's glass insulators are in operation world wide. The SYGG's glass inulators passed type/design tests per ANSI C29-2B, CSA 411-1-16, and IEC 60383.
The voltage ratings up to: 1000kV AC, +-1100kV DC
The mechnical ratings up to: 840kN
