This series of testing transformer uses advanced production equipment, adopts the new technology of coil winding epoxy vacuum casting and CD type iron core. Compared with similar oil-immersed transformers, it significantly reduces the weight and volume, improves the insulation strength and humidity resistance, and effectively weakens the magnetic flux leakage and greatly strengthens the transformer's ability to withstand the impact of the test short-circuit current.

This series of testing transformer can also make DC high voltage test by using a matched high-voltage silicon stack.

This series of testing transformer have features of light weight, small volume, beautiful appearance, stable performance, convenient usage and carrying, especially suitable for site operation, are new generation high voltage testing transformer used for AC and DC in China.

This series of testing transformer are applicable to power system and all power users to detect on site the insulating performance test of all electrical equipment, high voltage power sources of all appliance's voltage system or equipment with DC high voltage small current.
