Structural characteristics of JDZ6-20, 15R voltage transformer :JDZ6-20, 15R voltage transformer is a fully enclosed structure, which is made of epoxy resin vacuum cast in the user, and has the characteristics of arc resistance, ultraviolet resistance and aging resistance. The shape adopts the umbrella group, the surface creepage distance is large, and the secondary appearance terminal is sealed with a metal protective cover, which is rain-proof, dust-proof and corrosion-resistant. It is an ideal substitute for old-fashioned oil-immersed products.

Matters needing attention :

When the voltage transformer has a current, the secondary winding cannot be short-circuited, otherwise the transformer will be burned.

For the repeated power frequency withstand voltage of the primary winding, the test should be carried out under 80% of the specified test voltage value.
