Dry Type Testing Transformer
I.Product Introduction
This series transformer uses advanced production equipment, and new technology of coil
winding epoxy vacuum pouring and CD-type iron core, which obviously reduce weight and
volume, improve insulating strength and humidity resistance level, effectively weaken
leakage magnet resulting in greatly enhance the ability to withstanding impact of testing
short circuit current of transformer.
This series products 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 products 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.
