一、Description
        The outdoor current Uansfonner is an en - closed, post type and outdoors product.  It is used for mete-
ring electric energy and current, relay protection up to rated frequency 50Hz or 60Hz and rated voltage
35kV.  The transformers can be executed accordinl; 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 res-
in( made in Switzerland ciba, the type is CW5837). The product has much merit, such as: electric arc re-
sistances, ultraviolet ray and aging resistance long working time, long creepage distance, little partial dis-
charge 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 from the hermetic leading - out
box under the product.
