Semi-closed Dry Voltage Transformer

JDZ-10kV type are  single phase double coil,semi-enclosed indoor voltage transformer of epoxy resin casting full insulation structure.The core is made of high quality silicon steel sheet. All windings are cast by epoxy resin, which has characteristics of  good insulation, impact resistance, mechanical pressure resistance, and can protect the winding from moisture. 

The mark of the outlet terminal of primary winding is A, X; The marks of the terminal of the secondary winding lead wire are a and x, which are clearly marked on the pouring body next to the grounding mark on the clamp. The earthing bolt is provided for earthing and the lower bracket is provided for installation. The whole structure is compact and easy to use.

The voltage transformer is suitable for 12kV power systems to turn high voltage into low voltage and large current into small current for measurement or protection systems. In order to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.
