Product technical parameters and structure dimensions



Product features and scope of use 
Current transformer have the whole-sealed structure with epoxty resin as its main insulation. Its core adopts the crystallitic alloy or excellent silicon steel sheets to enwind becoming annular, then secondary leads are enwinded on it evenly. Primary conducts are winded by insulation belt to avoid short circuit between conducts. There are earth bolts and holes suitable for mounting on the bottom of the product suitable the mounting
