GFJDZX9-33SG 0.2/3P CLASS SINGLE POLE 33KV INDOOR VOLTAGE TRANSFORMER
INTRODUCE
GFJDZX9-33SG is one dry type indoor service voltage transformer. The core is encapsulated with type B epoxy resin which provides excellent internal dielectric properties and mechanical strength, ensuring a long mechanical and electrical life. The voltage transformer is maintenance free.
The core is built with high permeability grain oriented silicon steel laminations for low losses. The windings are copper wire with copper plate double isolation. The concentric distribution of the coils prevents magnetic flux leakage, achieving greater accuracy and higher capacity to withstand mechanical stresses in adverse operating conditions.Its limiting therminal Output can reach 800(VA)It has excellent short circuit and thermal withstand capabilities.
All of our indoor voltage transformers are strictly comply IEC60044-2, IEC61869-1,3, IEC60186, ANSI/IEEE C57.13, BS 7729, GB1207-2006, GB/T 20840.3-2013, GB/T 22071.2-2017, GB/T 20840.102-2020.
