一、 Description

    The current transformers are casting resin insulated, wall through and multi turn type product. It is used for metering electric energy and current.relay protection in the electrical system of rated frequency 50Hz or 60Hz and rated voltage lOkV.

三、 Construction
    This current transformer is semi enclosed and wall through type. The primary and secondary windings are both of resin casting insulation. The sheet iron piled core and fixing board are gripped on the casting resin body. The hoard has nameplate, and fixing holes for the wall - through type fixing in the switch cabinet.
