Rated secondary current: 5A or 1A.
Rated insulation level£º12/42/75kV¡£
Structure and Feature
The 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.
