    Structure feature

    The product has a leg type.totally-enclosed structure and its ring core,primary winding and secondary winding are casted resin nsulated. Reinsforced insulation makes it workable uner humidity condensation nd pollution Il.Three wiring ways are for your choise(A.B.C).


    The outlet marks of the product are:primary P1 to P2,the secondary current from S1 to S2 through outside returncircuit. High voltage appears if secondary return circuit opens while primary current is flowing by.
