The JDZ11-36 is a 36kV indoor single-phase voltage transformer featuring a fully enclosed epoxy resin casting insulation structure. The primary winding, secondary winding, and annular core are all coated within the epoxy resin, enhancing resistance to dirt and moisture. This model incorporates an umbrella skirt design, which increases the external insulation creepage distance for improved safety and reliability.
Widely used indoors, the transformer is suitable for measuring current, electric energy, and protective relaying in isolated neutral systems operating at frequencies of 50Hz or 60Hz, with a highest equipment voltage rating of up to 40.5kV. It complies with IEC 60044-2:2003 and IEC 61869-1 standards to ensure high performance and safety.
