JDCF series oil-immersed electromagnetic voltage transformer

Product Introduction:

JDCF series oil-immersed electromagnetic voltage transformer is a voltage transformer with transformer oil and insulating paper as the insulating medium. It protects the measuring instrument and relay in the power system, and miniaturizes and standardizes the secondary equipment. It is an indispensable power equipment in the substation.

Product features:

It has the characteristics of rapid transient response. Meet IEC 61869-3, CFE NRF-026, IEEE57.13 and other technical standards. Single-stage electromagnetic voltage transformer, the upper part is an expander component, the middle part is a porcelain sleeve component, the bottom is a fuel tank, and the body parts are placed inside. The body of the device comprises a winding and a capacitor voltage balancing plate, and the winding and capacitor voltage balancing plate are wrapped into one body. Product size is small, light weight, large load, dielectric loss stability.
