High capacity high accuracy, low loss factor. 10 years Japan Fuji supplier relationships Standard:GB1208-2006 and IEC 660044-1
Discription
This series of current transformer is introduction of German technology, designed structure same as AS12 series, and the use of advanced materials and technology, applicable to indoor current, power measurement and relay protection in rated voltage 10kV and below power system with rated frequency 50Hz-60Hz.
This product is the new generation of high accuracy, high dynamic thermal stability and high capacity. According to various requirement, It can be 2~4 windings, and are suitable for
KYN28A-12 (GZS1) high voltage drawer-type cubicle switchboard and other GZS.
construction
Current transformer is epoxy resin fully enclosed casting post type, has a good ability of anti-pollution and moisture proof, Also suitable for hot and humid regions.
The secondary windings of transformer consists of one amorphous alloy core for measurement and one or two Japan imported coiled silicon steel core for protection.
Each front and two side have a hole for secondary circuit, and has preventing electricity-stolen shield, make it safe and reliable.
