Dry Type Hipot Tester,
150kV Hipot Tester
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 impact.
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 source.
Small and light, with compact structure, no oil leakage, maintenance unnecessary, simple wiring
