一、Description
    The current transformers are casting resin, fully enclosed, busbar and wall - through type product
They are used for metering electric energy and current, relay protection in the electrical system up to rated freque,ncy 50Hz or 60Hz and rated voltage 10 kV.  The transformer can be executed according to the standards IEC60044l and CB1208.
二、 Type designation
 

三、construction
       The LM25 - 10 current transformer is busbar and wall - through type product with insert contact box.
       Th8 current transformer is insert - construction if concerted with the contact box for a special purpose of CH28 -10Q type.It can change the current transformers of different current easily; furihermore it needn't changing and adjusting the contact box. It can be installed, used and repaired easily.
    The LM25 - 10Htype current transformer is casting resin insulated and wall through construct.  It is insert - construction if concerted with the contact box for a special purpose of CH28A - lOQ type.  The terminal PI of the primary winding is as the static contact of the switch cabinet and placed inside the epoxyresin insulation cavity.
