GTB series adopts the new technology of coil winding epoxy vacuum
pouring and CD type iron core. Comparing with the same kind of oil
immersed transformer, it obviously reduces the weight and volume,
improves the insulation strength and the anti humid range in the
quality, and effectively weakens the magnetic leakage. The
transformer is strong enough to withstand short-circuit current
This series of devices are suitable for the power system and the
electric power users to test the insulation performance of various
electrical equipment in the field, or working as high voltage
Small and light, with compact structure, no oil leakage, no
maintenance , simple wiring.
The input voltage of this series of products is 200V (400V). By
changing the input voltage according to the need of electromagnetic
induction principle, the output high voltage can be continuously
adjusted from zero volt to the highest rated value.In the DC
withstand voltage and leakage current test, as long as the high
voltage . silicon stack is rotated in the high voltage output
terminal, the input voltage can be
changed, thus obtaining different values of DC high voltage output
This series of products is shown in Figure 1 in detail.
When used as cascade, its connection is shown in Figure 2.
