JDCF-66W Series 72.5kV Voltage Transformer

Our JDCF-66W series voltage transformers feature single-phase porcelain insulation with limited-position sealing, delivering stable insulation and strong anti-ferroresonance capability for 72.5kV systems.

• Rated voltage ratio of 66/√3/0.1/√3/0.1√3/0.1/3kV with insulation level of 72.5/140/325kV.

• Accuracy combinations of 0.2/0.5(3P)/3P(6P) with rated output up to 75/100/100VA and thermal limit output of 1000VA.

• Low magnetic flux density ensures excellent excitation characteristics; low partial discharge and dielectric loss for reliable operation.

• Anti-pollution design with creepage distance of 2700mm, suitable for demanding outdoor environments.

• Fast delivery, reliable quality, responsive service, and extensive project experience backed by our company.
