一、Description
    The LZZ - 12W current transformer is afull enclosed and prop shape product.  It is used for metering electric energy and current, relay protection in the electric power system up to rated frequency 50Hz or 60Hz and rated voltage lOkV.  The transformers can be executed according to the standards IEC60044 -1 and GB1208.
二、Type designation

三、 Construction
  The type of current transformer is a full en - closed and prop shape product.  It is made by outdoor resin( made in Switzerland ciba, the type is CW5837).  The product has much merit, such as: electric arc resistances, ultraviolet ray and aging resistance, long working time, long creepage distance, little partial discharge and large caliber of resistance to over - voltage, etc.  The primary winding, secondary winding and core are made up together and poured in the cast. The primary winding's terminal, Pl and P2, is on the product, and the secondary winding's terminal, Sl and S2, is leaded out underside of the product.
