LZW-24 Current Transformer
Summary
The supporting-type current instrument transformers LZW-24 are fully enclosed and cast in epoxy resin. The transformers are designed for electric power systems of rated frequency 50Hz/60Hz and rated voltage o f 35kV. They are used for outdoor mounting. The performances of the products meet standards IEC60044-1 and GB1208-2006. The products are applied to metering electric energy, voltage controlling and relay protection.
