10KV Current transformer
Model:
LZZBJ10-10(A,B,C)
1. Description
The current transformer of the type LZZBJ10-10(A,B,C) is casting resin and fully enclosed 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 10kV.The current transformer has the character of small volume,light weight,superior insulation,high accuracy, high dynamic multiple and so on.We also can produce every kinds of products according to the consumers’ requirements.It,s flexible.The transformers can be executed according to the standards IEC44-1:1996 and GB1208-1997.
